WARNING

Electrical Shock Hazard

Disconnect power before

servicing.

Replace all parts and

panels before operating.

Failure to do so can

result in death or

electrical shock.

IMPORTANT

Electrostatic Discharge Sensitive

Electronics (ESD)

ESD problems are present everywhere. ESD

may damage or weaken the machine control

electronics. The new control assembly may

appear to work well after repair is finished,

but failure may occur at a later date due to

ESD stress.

■Use an anti-static wrist strap. Connect

wrist strap to green ground connection

point or unpainted metal in the appliance

-OR- Touch your finger repeatedly to a

green ground connection point or

unpainted metal in the appliance.

■Before removing the part from its package,

touch the anti-static bag to a green ground

connection point or unpainted metal in the

appliance.

■Avoid touching electronic parts or terminal

contacts; handle machine control

electronics by edges only.

■When repackaging failed machine control

electronics in anti-static bag, observe

above instructions.

DIAGNOSTIC GUIDE

Before servicing, check the following:

■Make sure there is power at the wall outlet.

■Has a household fuse blown or circuit breaker

tripped? Was a regular fuse used? Use a

time-delay fuse.

■Is dryer vent properly installed and clear of lint

or obstructions?

■All tests/checks should be made with a VOM

(volt-ohm-milliammeter) or DVM (digital-

voltmeter) having a sensitivity of 20,000 Ωper

volt DC or greater.

■Check all connections before replacing

components. Look for broken or loose wires,

failed terminals, or wires not pressed into

connectors far enough.

■A potential cause of a control not functioning is

corrosion on connections. Observe

connections and check for continuity with an

ohmmeter.

■Connectors: Look at top of connector. Check

for broken or loose wires. Check for wires not

pressed into connector far enough to engage

metal barbs.

■Resistance checks must be made with dryer

unplugged or power disconnected.

TEST #4a Thermistors

Outlet Thermistor

The machine control electronics monitors the

exhaust temperature using the outlet thermistor,

and cycles the heater relay on and off to maintain

the desired temperature.

Begin with an empty dryer and a clean lint screen.

1. Plug in dryer or reconnect power.

2. Start the Timed Dry cycle.

3. If after 60 seconds, F:22 or F:23 flashes in the

display and the dryer shuts off, the thermistor

or wire harness is either open or shorted.

➔Unplug dryer or disconnect power.

➔Check wire connections at the machine

control electronics and thermistor. See

Accessing & Removing the Electronic

Assemblies, page 9, and for thermistor

location see figure 11, page 6.

➔If wire connections are OK, check the outlet

thermistor resistance per step 5.

4. If F:22 or F:23 does not flash in the display,

the connections to the thermistor are good.

Therefore, check the exhaust temperature value

at any or all of the temperature levels in

question, using the Timed Dry cycle, and the

following process:

Hold a glass bulb thermometer capable of

reading from 90° to 180°F (32° to 82°C) in the

center of the exhaust outlet. The correct

exhaust temperatures are as follows:

EXHAUST TEMPERATURES

temperature

Medium 140°±5° (60°±3°)

Low 125°±5° (52°±3°)

Extra Low 105°±5° (41°±3°)

*The measured overshoot using the glass bulb

thermometer in the exhaust outlet can be 30°F

(17°C) higher.

5. If the exhaust temperature is not within

specified limits, or you have come here from

step 3, perform the following:

NOTE: All thermistor resistance measurements

must be made while dryer is unplugged or

disconnected from power.

ELECTRIC DRYER: Remove the P4 connector,

then measure the resistance between P4-3 (red

wire) and P4-6 (red wire) at the connector.

➔If the resistance is OK, check P4-3 and P4-6

to machine ground.

➔If resistance is greater than 0 (zero), replace

wiring harness.

GAS DRYER: Remove the P14 connector, then

measure the resistance between P14-3

(red-white wire) and P14-6 (red-white wire) at

the connector.

➔If the resistance is OK, check P14-3 and

P14-6 to machine ground.

➔If resistance is greater than 0 (zero), replace

wiring harness.

➔Check wire connections at the machine

control electronics and inlet thermistor. See

Accessing & Removing the Electronic

Assemblies, page 9, and for inlet thermistor

location see figure 11, page 6.

➔If wire connections are good, remove the

wires from the inlet thermistor/high limit

thermostat assembly and replace the

assembly.

➔Plug in dryer or reconnect power.

3. If F:24 or F:25 is not an error that is displayed

in the Diagnostic Test Mode, the connections to

the thermistor are good. Therefore, check the

thermistor’s resistance value, using the

following process:

➔Unplug dryer or disconnect power.

➔Access the heater assembly. See figure 2,

page 3; and Removing the Toe Panel,

page 9.
