FORCED AIR SYSTEMSFORCED AIR SYSTEMS

FORCED AIR SYSTEMS

On all forced air models, an air circulating

fan draws air from across the evaporator and

directs it to the fresh food and freezer com-

partments. A carefully measured amount

of chilled air is directed into the fresh food

compartment through a baffle to maintain

the desired fresh food compartment tem-

perature. The greater part of chilled air is

directed into the freezer compartment to

maintain freezer temperature. Forced air

models use a fan cooled condenser. De-

pending on the model, the evaporator is

automatically defrosted every eight hours

of compressor run time. Defrosting is ac-

complished by a defrost heater activated by

a timer. The accumulated moisture is

drained into a defrost pan located in the

compressor area of the cabinet.

AIR FLOW - FORCED AIR SYSTEMSAIR FLOW - FORCED AIR SYSTEMS

AIR FLOW - FORCED AIR SYSTEMS

The airflow balance between the fresh food

and freezer compartments is an important

factor in maintaining proper compartment

temperatures in a forced air refrigeration

system. A baffle is used to regulate the

amount of chilled air directed into the fresh

food compartment. If a colder freezer com-

partment temperature is desired, the baffle

is adjusted so that less air is directed into

the fresh food compartment. This causes

the compressor to run longer since the ther-

mostat sensing element is located in the

fresh food compartment. Cold air is drawn

across the evaporator and into the fan. A

portion of the air is deflected into the fresh

food compartment where it absorbs heat

and returns to the fin and tube evaporator

1-3

The following general information explains

several methods for checking operation of

the refrigeration system. This information

applies to all systems covered in this

manual. The correct operation of a refrig-

eration system is dependent upon the

proper function of each of the parts com-

prising the system.

If the system does not operate properly

(long run periods, warmer than normal tem-

peratures), the trouble may be caused by

one of the following conditions:

(1) - Restricted Capillary Tube(1) - Restricted Capillary Tube

(1) - Restricted Capillary Tube

The opening of a capillary tube is about the

same diameter as the period at the end of

this sentence. Because of this, it is easy to

restrict the tube. Extra precautions should

be taken when any service procedure in-

volves moving or touching the capillary

tube. The slightest kink can cause a com-

plete tube restriction.

Restrictions of the capillary tube may be

caused by: (1) moisture freeze-up, (2) for-

eign particles lodged in the tube, or (3) a

bend or kink.

If the capillary tube is restricted, there will

be a noticeable lack of frost on all cooling

surfaces; the compressor may operate for

a short period of time and cycle on the

overload. Because some models can hold

the entire charge in the condenser, the com-

pressor may run continuously and a defi-

nite vacuum will be noticed in the low side.

When moisture freeze-up causes a restric-

tion, it usually occurs at the outlet end of

the capillary tube. Normally, frost buildup

can be detected in this area.

dryer, use low heat. Never use a torch.

At the discharge end of the capillary, apply

heat. If there is enough head pressure, and

if the restriction is caused by moisture

freeze-up, you will be able to hear a gurgling

noise as the heat releases the refrigerant

through the tubing.

It is possible that this moisture will be ab-

sorbed by the drier and remedy the trouble.

However, if the freeze-up reoccurs, you

must replace the drier.

A kink in the capillary tube will reveal the

same symptom as a moisture freeze-up,

except for the accumulation of frost. Where

possible, check the capillary tube and

straighten any kinks to relieve the restric-

tions. Check the unit operation. If the con-

dition persists, replace the defective part.

If the freeze-up condition does not exist and

there is not a kink, you can assume that a

foreign particle is causing the restrictions.

The only remedy in this case is to replace

the restricted part.

(2) - Partial Restriction In Low Side(2) - Partial Restriction In Low Side

(2) - Partial Restriction In Low Side

Tubing Tubing

Tubing

Bent tubing, foreign matter, or moisture in

the system may cause a partial restriction

in the low side tubing. This is usually indi-

cated by frost-free tubing between the re-

through the return opening in the divider.

However, most of the air moving across the

evaporator is blown through the freezer air

tunnel and circulated throughout the freezer

compartment. It then circulates back across

the fin and tube evaporator where it begins

another cycle.

striction and the capillary tube and by frost-

covered tubing between the restriction and

the suction line. The restriction acts like a

second capillary tube, increasing the pres-

sure ahead of it (warming) and decreasing

the pressure beyond it (cooling). To con-

firm the existence of a restriction in the low

side tubing, perform operational pressure

checks.

(3) - Slow Leak In System(3) - Slow Leak In System

(3) - Slow Leak In System

On forced air models, long run time will be

noticed during the early stages of a leak. As

the refrigerant continues to escape, both

compartments will gradually warm up and

the compressor will run continuously. The

freezer will probably warm up first.

4) - Incorrect Refrigerant Charge4) - Incorrect Refrigerant Charge

4) - Incorrect Refrigerant Charge

The sealed unit may have too much refrig-

erant (overcharged system) or too little re-

frigerant (undercharged system). The para-

graphs below will inform you on how to

recognize a system with these defects.

An overcharged system may have a frost

back condition appearing on the suction

line. When the compressor stops, the frost

melts and drips on the floor. A heat ex-

changer separation will also cause this

symptom.

An undercharged system, depending on the

degree of undercharge, will operate with

temperatures above normal and the com-

pressor run time will be increased. The

greater the undercharge, the higher the tem-

perature will be and the longer the run time.

An undercharged system must be purged,

evacuated, and recharged with the proper

amount of refrigerant. Before recharging,

test for refrigerant leaks.

Leak detectors compat-

possibility of contaminating the sealed sys-

tem with moisture, using soap bubbles can

cause problems, especially if drawn into a

of moisture entering the system, the use of

wet rags or towels to cool a brazed joint

should be avoided.

Any time a sealed sys-

ferent, using a new desiccant which pro-

vides system compatibility and proper

moisture absorption. Use of the old type

drier on new R134A systems would result

in a repeat sealed system failure. Part num-

Additionally, "unsoldering" a joint, rather

than the score and break method, is not ac-

to the atmosphere until you are ready to

braze it into place. Before installing a new

compressor, pull a plug to be sure the unit

is still pressurized. If no pressure exists, do

not use the compressor. If pressure exists,

reinstall the plug to ensure non-contamina-

tion during the service procedure.

SYSTEM FLUSH - SYSTEM FLUSH -

SYSTEM FLUSH -

Flushing of the system

is required whenever there has been a low

side leak, plugged capillary tube or com-

pressor replacement. This is a procedure

in which R134A refrigerant is flushed

through the system and into the recovery

system to remove moisture and non-

condensables which may have entered the

open system. The compressor must be

isolated during the flush procedure, in or-

der to prevent contaminants from being ab-

sorbed into the ester oil, resulting in a con-

taminated system.

The system flush procedure will be done

in two parts. First, the condenser, including

the yoder loop, will be isolated by means

of process tube adapters and flushed with

4 ounces of R134A. After the drier has been

replaced, the entire sealed system, minus

the compressor, will also be flushed with 4

ounces of the refrigerant. This second step

can take about 15 minutes in order to circu-

late the refrigerant through the condenser,

the drier, the capillary tube, the evaporator

and out the suction line into the recovery

equipment. During this 15 minutes, the old

compressor can be removed and the re-

placement set into place, mounted and pre-

pared electrically. The compressor is to-

tally installed except for the final brazing of

the suction and discharge lines.

All refrigerators cool by removing heat

from the cabinet rather than pumping in cool

air. In a conventional refrigerator, liquid re-

frigerant enters the evaporator and vapor-

izes (boils) due to the low pressure, creat-

ing a very cold surface which removes heat

from inside the cabinet. This causes the re-

frigerant to boil (evaporate) into a vapor

state and be drawn into the compressor.

The compressor pressurizes the vapor and

pumps it into the condenser. The hot va-

por in the condenser gives off the heat into

the room. As the vapor cools, it condenses

back into a liquid and returns to the evapo-

rator to start the process over again. The

system continually soaks up the heat inside

the refrigerator and deposits the heat back

into the room.

• The compressor compressor

compressor compressor

compressor of the refrigeration sys-

tem serves two purposes: it ensures

movement of the refrigerant throughout

the system and it increases the pressure

and temperature of the vapor received

from the suction line and pumps the re-

frigerant into the discharge line. The

condenser receives this high tempera-

ture, high pressure refrigerant and al-

lows the heat to be released into the

cooler surroundings. This heat removal

"condenses" the refrigerant vapor into a

liquid.

pressure, a temporary access valve can be

installed on the compressor process tube.

To remove the valve after repair, a pinch off

tool may be used to seal the tube while the

valve is removed and the hole brazed shut.

To check high side pressure, a temporary

access valve should be installed on the dis-

charge line. When the high side valve is in-

moved upon completion of repair. Make

sure the gauges which are used to check the

operating pressures are accurately cali-

brated. When not connected to a system,

the gauge pointer should indicate zero pres-

to diagnose sealed system problems. Nor-

mal low side pressure will range from be-

low zero to about six pounds of pressure,

depending on several factors such as refrig-

erator model, ambient temperature, load

and customer usage. Normal high side

pressure is also dependent on external fac-

tors but will range in the 100 to 125 p.s.i.g.

range. Wattage and pressure figures will

vary based on the model and age of the re-

frigerator. Refer to the performance data

Diagnosisiagnosis

iagnosis

- Separated capillary tube. The

capillary tube must be connected to the suc-

tion line to provide proper heat transfer.

Without this transfer, liquid refrigerant in the

capillary tube enters the evaporator at a

slightly higher temperature thereby lessen-

ing the ability to remove heat from inside

the refrigerator. The customer complaint

would be long run time, slow ice produc-

tion, warmer fresh food temperature, in

general, poor overall performance. Another

symptom of a separated capillary tube

could be moisture on the floor behind the

refrigerator. The heat from the capillary tube

is utilized by the suction line to ensure that

vapor rather than liquid refrigerant is re-

turned to the compressor. If liquid is

present in the suction line, frost or moisture

forms on the outside of the line and even-

tually drips to the floor.

Once it has been determined through

proper diagnosis that a leak is present in the

sealed system, attempt to find the leak be-

fore opening the system if possible. To

check the high side for leaks, be sure that

the compressor is running. During run time

the high side pressure is greater. To increase

the pressure slightly, stop the condenser

fan blade or block the air flow through the

condenser. To check the low side for leaks,

stop the compressor. During off times, the

low side pressure will increase to equalize

with the high side. By warming the evapo-

rator, this pressure will increase. If too much

refrigerant has leaked out to create enough

pressure to locate the leak, add 4 ounces of

the proper refrigerant to the system and

proceed with the test procedure.

The presence of oil around a tubing joint

usually indicates a leak. Care must still be

taken to pinpoint the exact location. Re-

member that a leak detector compatible

with R134A refrigerant must be used. A

sealed system component, such as the

evaporator or yoder loop, should not be

condemned unless a non-repairable leak is

confirmed. This should be determined by

either locating the actual leak or by isolat-

ing the component from the rest of the sys-

tem and determining if it holds pressuriza-

tion or a vacuum - whichever method is

chosen.

Drier

Whenever the sealed system is entered, the

drier must be replaced. For R134A refrig-

erant systems, use a 13900-113900-1

13900-113900-1

13900-1 drier. This

drier has the proper desiccant suitable for

the refrigerant. The drier is stamped with

an arrow which indicates the direction of re-

frigerant flow. The drier inlet has two lines -

one connects to the yoder loop and the

other will be used as a process tube through

which the system sweep and final charge

will be made. The drier outlet will be con-

nected to the capillary tube. Care should

be taken to ensure that the capillary is not

inserted too far into the drier to make con-

tact with its internal screen, yet in far enough

to prevent restricting the small diameter

capillary tube opening with the solder alloy.

CondenserCondenser

Condenser

The condenser is a long folded tube which

receives the hot, high pressure vapor from

the compressor. While the most common

problem is keeping the condenser clean

from lint and dirt buildup which prevents

proper airflow and the required transfer of

the heat to the surroundings, it is possible

that due to an unrepairable leak or a non-

removable restriction, the condenser could

require replacement. As with any R134A

sealed system repair, the key to success is

the limiting of the time of atmospheric ex-

posure. Do not remove the plugs on the

condenser inlet and outlet tubes until the

new condenser is mounted in place and

made ready for brazing. The inlet side will

connect to the compressor discharge line

and the outlet to the yoder loop.

The evaporator is a long aluminum tube

folded or coiled within the freezer compart-

ment. If a leak is present in the evaporator,

it is not repairable and must be replaced.

On R134A systems, whenever the evapo-

rator is replaced, the heat exchanger must

also be replaced as well as the compres-

sor. The replacement evaporator will come

with the heat exchanger attached. Leave the

caps in place on the opposite end of the heat

The compressor is the "heart" of the refrig-

a "pump" sealed inside a steel case. The

pearance as the compressor used with R12

not to be interchanged,

otherwise system failure will result. Diag-

nostic procedures will be the same as with

the R12 refrigerant systems, except that the

high side pressure will be slightly higher and

the low side pressure will be slightly lower.

If a new compressor is to be installed, pull

one of the plugs to ensure that it is prop-

erly pressurized. If no pressure is observed,

do not use the compressor. If unit is pres-

surized, reinstall the plug and keep the com-

pressor sealed until it is installed and ready

for solder connections. Whenever the com-

pressor is replaced on a R134A refrigera-

tor, the sealed system must be flushed

(see(see

Before accessing the sealed system, it is

necessary to determine that the problem

is actually a sealed system problem by

utilizing a wattmeter, thermometer, visual

and touch indicators. Once it has been

determined that the problem is in the

The sweep charge is a method of purging

the sealed system of moisture, air and po-

tential contaminants. Also during this pro-

cedure, the system may be checked for

leaks before the final charge. If this proce-

dure is followed as outlined, it will allow for

the capture of 90-95 percent of the available

refrigerant, thereby ensuring that the sys-

tem will operate as designed.

The sweep procedure for R134a refrigerant

systems is made after the system has been

repaired and/or flushed. Three (3) ounces

of refrigerant R134a is added to the system,

circulated by the compressor for 5 minutes

and recovered. Since a new drier - part

Overload ProtectorOverload Protector

Overload Protector

The overload protector prevents the com-

pressor from burning out its electrical wind-

ings in the event the compressor becomes

overheated or draws too much current. The

overload trips, opening the circuit to the

compressor. If it does this repeatedly, the

compressor is said to be cycling on the

overload.

Cycling on the overload may be caused by:

1. Insufficient air circulation around the

compressor and condenser.

2. Pull-down on the compressor, caused

by a large quantity of warm food

placed in the refrigerator.

3. Compressor stalling due to lack of pres-

sure unloading.

PTC STARTING DEVICE AND RUNPTC STARTING DEVICE AND RUN

PTC STARTING DEVICE AND RUN

CAPACITORCAPACITOR

CAPACITOR

The PTC solid state starting device is a push-

on component mounted to the start and run

terminals of the compressor. This device

is connected in parallel with the run capaci-

tor and is in series with the compressor start

windings. This will produce a short circuit

across the run capacitor during the com-

pressor starting sequence and full current

is applied to the start windings as well as

the main winding. Since the PTC device is

temperature sensitive, a variance in its tem-

perature causes a change in its resistance.

When current is first applied to the com-

pressor, the PTC device's low resistance

shorts out the run capacitor; thus produc-

ing adequate motor starting torque.

As the compressor motor approaches run-

ning speed, the current through the PTC

device causes the temperature and resis-

tance of the PTC device to increase to where

it appears to be an open circuit. The com-

pressor continues to operate on the run

winding in parallel with the series combina-

tion of the run capacitor and start winding.

The refrigerator has two temperature

controls:

1. Fresh Food Compartment -Fresh Food Compartment -

governs the compressor operation

accordingly.

2. Freezer Compartment - Freezer Compartment -

Freezer Compartment - Freezer Compartment -

Freezer Compartment - The freezer

compartment control adjusts the

damper door which regulates the

amount of air allowed to enter the fresh

food compartment.

Turning the freezer temperature control to

the coldest settings reduces the flow of

chilled air to the fresh food compartment.

The fresh food temperature control uses a

sensing element that must be cooled suffi-

ciently before stopping the compressor.

The reduced air flow causes longer com-

pressor run time and colder freezer tem-

peratures, while maintaining the required

fresh food compartment temperatures.

Conversely, by turning the freezer tempera-

ture control to the warmest setting, you in-

crease the flow of air into the fresh food

compartment and decrease the flow to the

freezer. This cools the fresh food tempera-

ture control sensing element faster, result-

ing in shorter compressor run times and

warmer freezer compartment tempera-

tures. The fresh food compartment will

stay near the recommended fresh food tem-

perature, unless the freezer temperature is

turned to an extreme temperature. The dif-

ferential between cut-in/cut-out tempera-

ture will vary approximately 100F.

DEFROST TIMERDEFROST TIMER

DEFROST TIMER

The freezer evaporator defrosting system

is actuated by an electric timer. The timer

is mounted in the control housing located

in the fresh food compartment.

1st Click -1st Click -

1st Click - The timer turns off the compres-

sor and freezer fan circuit for approximately

23 minutes, and it energizes the defrost

heater. Once the temperature of the defrost

termination thermostat reaches the cut-out

point, the termination thermostat will open

the circuit to the radiant heater. However,

the compressor circuit remains open for the

duration of the defrost interval.

2nd Click -2nd Click -

2nd Click - The timer switches off the de-

frost circuit and starts the compressor,

freezer fan, and the condenser fan motor.

The compressor and fan motors are now

governed by the temperature control for a

period of approximately 8 hours of the com-

pressor run time, after which a new defrost

cycle begins.

The timer control shaft is designed for

screwdriver advancement. When manually

setting the timer to initiate defrosting, turn

the control shaft clockwise until you estab-

lish the approximate location of the defrost

cycle. Then turn the shaft slowly, and stop

immediately when the first click is heard.

The schematic illustrates the timer circuits

in sequence.

ADAPTIVE DEFROST CONTROLADAPTIVE DEFROST CONTROL

ADAPTIVE DEFROST CONTROL

The adaptive defrost control assembly is a

microprocesser controlled defrost timer.

This new control allows defrost to occur

only when needed, compared to mechani-

cal timers which defrost at a preset interval

whether it is necessary or not. The new

control will continually adjust defrost inter-

vals based on the amount of time the de-

frost heater is energized. This allows the

defrost intervals to be adjusted closer to

the optimum defrost interval based on use,

thus saving energy.

These models use a metal sheath heater to

remove accumulated frost from the freezer

evaporator and drain trough during a de-

frost cycle.

The defrost timer (models) energizes the

defrost heater every 8 hours of accumu-

lated compressor run time. When the tem-

perature in the thermostat area reaches ap-

proximately +43o F. the thermostat contacts

open the circuit to the defrost heater.

An ohmmeter check will determine if all

phases of the defrost cycle are functioning

properly. The defrost thermostat contacts

open at approximately +43o F. and close at

approximately +15o F.

The defrost thermostat has a 240K ohm re-

sistor connected internally across the two

terminals. This resistor permits checking

the defrost heater when the evaporator tem-

perature is +15o F. or higher.

An ohmmeter can be used to test the de-

frost heater and thermostat without disas-

sembling the freezer compartment even if

the evaporator temperature is +15o F. or

higher. To check, proceed as follows:

The auger motor and solenoid are located

behind the storage bin. The yoke, fastened

to the motor, engages the drive ring and

turns auger in a clockwise direction. Both

the yoke and drive ring are designed to pre-

vent a loosening of the yoke by exerting

counter pressure while in operation.

The auger motor makes one revolution ap-

proximately every three seconds. To de-

termine the free movement of the auger

motor, place the selector switch in either

cube or crushed position (slide selector

models). On electronic models, push the

cube or crushed selector pad. Open the

freezer door, push and hold the cabinet in-

terlock switch in the closed position while

pushing the dispenser actuator pad.

The solenoid is energized only when the

selector switch is in the cube position. This

will pull back the actuated blades. To deter-

mine the free movement of the solenoid/

yoke assembly, place the selector switch

(slide selector models) in the cube position.

On electronic models, push the cube selec-

tor pad. Open the freezer door. While push-

ing the dispenser actuator pad, push and

hold the cabinet interlock switch in the

closed position. Observe the control rod

yoke for vertical movement.

The auger motor and the solenoid/control

rod yoke assembly are easily removed.

WATER PROBLEMSWATER PROBLEMS

WATER PROBLEMS

Water quality can cause ice makers to fail

or produce unacceptable cubes. If mineral

content or sand is a problem, the screen in

the fill valve can restrict. A particle of sand

can keep the valve from seating properly.

Results will be small crescents (or no ice)

or flooding of the ice container if the water

valve does not close.

Mineral content can also lime up the mold

causing wicking of water over the mold and

poor cube release. Silicone is applied at the

upper edges, around the fill cup and

stripper.

TEMPERATURE PROBLEMSTEMPERATURE PROBLEMS

TEMPERATURE PROBLEMS

Temperatures in the freezer section which

average above the normal 0o +/- 5o will slow

the production of ice. Complaints of inad-

equate crescent production may be cor-

rected by setting the freezer to a colder tem-

perature in this one-revolution ice maker is

17o +/- 3º. Obviously, the ice will be well

frozen when these temperatures are

If the thermostat is diagnosed as defective,

it can be removed and replaced easily. Re-

move the module from the mold by taking

out two Phillips screws.

Using needle nose pliers, grasp one of the

thermostat clips and pull out. Press in new

thermostat, making sure that pins are prop-

erly indexed. Using this procedure, it is not

necessary to remove the electrical assem-

bly. If you are replacing the module, trans-

fer the clips to the new mold support. (Use

new thermal bonding material.)

Pull the module free of the mold and you

will see the thermostat on the mold side.

CLIMATE ZONE TECHNOLOGYTM

STORAGE DRAWERS

(Select Models)

Climate Zone TechnologyTM Storage Drawers

prolong the freshness of meats, fruits and

vegetables. The top drawer accommodates

meats, citrus fruits and fresh produce. The

middle drawer holds citrus fruits and fresh

produce. Climate Zone TechnologyTM

drawers are equipped with Automatic

Humidity Control*. The drawers are set to

provide optimal temperatures and a

numerical temperature display for each food

setting according to the chart below.

Climate Zone TechnologyTM can also be

turned off, and the drawers operate as

standard sealed crisper drawers with no

temperature display.

Notes:

• If a Climate Zone TechologyTM drawer is

left open the display will flash. Close the

drawer completely and the display will

return to normal.

• After prolonged drawer openings and /or

loading the drawers, etc. the

temperature readout may rise by a few

degrees. This is normal. The

temperature will recover in a short

period of time.

• Handle fresh meat with care to avoid

cross-contamination. Store meat in

airtight containers and be sure to wipe

up spills of meat juices immediately

using hot, soapy water. Disinfect drawer

with liquid chlorine bleach according to

label directions and rinse with clean

water.

• For enhanced flavor, store hard cheeses

on the Citrus setting.

• Frozen meats will thaw very slowly on

the Meat setting. Most thawing should

be done outside of the drawers, on the

lowest shelf in the refrigerator.

•Under heavy usage conditions during

hot, humid weather, the exterior

surfaces of the Climate Zone

TechnologyTM drawers may fog or sweat.

This is normal. The condensation will

clear once the door is closed for a period

of time.

• Due to the accuracy and the location of

the Climate Zone Technology™

temperature sensor system, drawer

temperatures measured with house hold

refrigerator thermometers may vary

from the drawer temperature display.

This is normal.

Item Storage Temperature

Citrus 39º F

Vegetables 34º F

Meats 31º F

16010154 SECTION 1. GENERAL INFORMATION 1-5

• If Climate Zone Technology™ drawers

are not opened for a period of four

weeks, they will automatically go to the

16010154 SECTION 1. GENERAL INFORMATION 1-6

WATER FILTER CHANGE REMINDER

(Select Models)

For some refrigerator models featuring

water filters, the Water Filter Change

Reminder function monitors the life of the

filter and provides a reminder when it is time

for the filter to be changed.

When the system detects either 12 months

of usage, or the filtering of 416 gallons of

water (whichever comes first), the CHANGE

FILTER indicator light will illuminate. This

indicates that the water filter should be

changed and the light reset.

To reset CHANGE FILTER light: Press and

hold the LIGHT and LOCK pads until the

CHANGE FILTER light blinks (approx. 3

seconds). The control is now reset for 12

months or another 416 gallons.

Note: The Water Filter Reminder will

operate if the filter bypass is in place.

AUTOMATIC HUMIDITY CONTROL

(Select Models)

Some crispers are equipped with an

automatic humidity control system,

eliminating the need for manual humidity

slide controls on the drawer. A fabric-like

material* covers small air vents in the

drawer cavity. This material controls the flow

of moist air out of the crisper to provide the

optimum environment for your food. If a

food spill should occur on the air vent or

mesh material, wipe with a clean, damp

cloth.

*Maytag Automatic Humidity Control

system features a unique, patented material

called Shape Memory Polymer (SMP) that

when laminated to fabric becomes DIAPLEX.

DIAPLEX is manufactured by Mitsubishi.

CHECKING AND REPLACING THE AUTO

DAMPER BIAS HEATER

The CZT bias heater is a resistive heater

attached to the auto damper with a metal

spring clip. The main purpose of the heater

is to allow more cold air into the freshfood

compartment when both pans are in the

normal storage (off) mode. This is

accomplished by heating the auto damper

bellows, which results in the damper door

being opened further. The auto damper still

regulates the airflow into the freshfood, but

the control band has now been “biased” or

shifted by the supplemental heater.

Power is supplied to the heater whenever

BOTH crisper fans are off. This occurs under

the following conditions: when BOTH pans

are in the normal storage (off) mode; when

the refrigerator is in defrost (this includes

the drip time); when BOTH pans are open;

and when BOTH of the pan temperatures

are above 60 F.

wire leads. Using an ohmmeter check the

bias heater, it should be 18K ohms

(±10%).

ICE MAKER WATER VALVE RELAY

The Water Filter Reminder product includes

an external relay to control the ice maker

water valves. This external relay is required

so the electronic control can monitor the

water usage of the ice maker. The water

usage through the dispenser is controlled by

a relay on the electronic control board, which

is also monitored. With the knowledge of the

combined water usage of the ice maker and

the dispenser, the control can determine

when the appropriate amount of water flow

through the water filter has occurred, and

will turn on the change filter light.

Disconnect the unit from the power source.

1. Remove the machine compartment cover.

2. Remove the the TN and WH/BU from the

water valve relay. Continuity check relay

coil using a volt-ohm meter if open

replace the relay.

IN-CABINET FUNCTION

TEST (ICFT)

• Climate Zone Technology™ Control

board assemblies have a self diagnostic

function called an “In Cabinet Function

Test “(ICFT)”

•Before conducting (ICFT) The

refrigerator control settings and

temperatures should be verified.

•Extreme fresh food control settings (to

warm or to cold) will cause the CZT

assemblies to exceed their limits.

• The CZT is designed to operate within

a range of freezer and fresh food

temperatures. (Freezer range -3 to +3°

F. Fresh food range 35 to 40° F.) If

temperatures exceed these ranges due

to adjustments of the refrigerator

controls, the CZT may no longer

maintain the desired temperature.

This problem is magnified when the

upper/lower CZT settings are meat

keeper/citrus.

•Therefore, it is important to determine

the refrigerator control settings prior

to troubleshooting.

•If the refrigerator controls are not at

(mid/mid), customer education will be

required.

•If the controls are set at (mid/mid)

verify the fresh food and freezer

compartments are within the ranges

given above.
