Introduction To The M-100B™ Cooking Computer

The M-100B cooking computer, illustrated on the following page, automatically maintains fryer
temperature to cook products according to preprogrammed cooking specifications. The computer also
acts as a cooking process timer, displaying the remaining cooking time for each product and alerting
the operator by sound and display message to shake or pull the product at the correct time. It also
signals quality control (hold-time) limits. The computer automatically adjusts cooking times to
compensate for variances in product temperature and basket load so that, for example, a full basket of
cold fries will be cooked to the same quality as half a basket of fries at room temperature.

computer, with the computer turned OFF (OFF in both displays) press the temperature check
switch. The displays will automatically cycle through the version number, power configuration (gas
or electric), EPRA configuration (On or Off), and frypot configuration (full- or split-).
The M-100B is factory-programmed with McDonalds’s cooking specifications for a group of seven
standard products. The cooking times and temperature settings for these factory-programmed products
can be changed by store personnel if required. Additionally, two test menus are available for store
personnel to program product names, cooking times, temperature settings, and shake or duty times for
products not included on the factory-programmed menu. The test menus can also be set to
automatically adjust the cooking rate to compensate for product variances.
For units equipped with built-in filtration, the computer times the polishing process and alerts the
operator when the polishing time has elapsed. (Polishing refers to circulating the vegetable oil
through the filtration system for a specified time.)

3–2

The fryer has two built-in high-limit protection features. If the temperature in the frypot reaches
approximately 410°F (210°C), the computer opens the heat relay circuit, turning the elements off. If
the temperature in the frypot reaches 450°F (232°C), a mechanical high-limit shuts off electrical
power to the elements. The operator should periodically test each of the high-limit protection features
to verify that they are operating correctly. Refer to Grills/Fryers Maintenance Requirement Card
(MRC) 15 for the procedure.

M-100B™ Computer Problem Condition Indicators

Open Drain Valve Indication
If, when the ON/OFF
switch is pressed to the ON position, the display reads IGNITION
FAILURE, verify that the drain valve is fully closed. A drain safety switch built into the drain valve
assembly prevents the elements from being energized if the valve is not completely closed. After
verifying that the valve is fully closed, turn the computer OFF* for at least 5 seconds, then turn it back
on. If the message reappears, there is a problem in the electrical circuitry of the fryer or the computer;
contact your Frymaster Factory Authorized Service Center (FASC).
* On early-version M-100B split-vat units, BOTH computers must be turned off, even though the
problem condition may be associated with only one vat.
Low Temperature Indication
If the frypot temperature drops to more than 45°F (25°C) below the programmed setpoint temperature
during the cooking cycle, the cook switches will lock, the display will flash lOW TEMP and an
audible alarm will sound. If the frypot temperature returns to a range between 45°F (25°C) to 15°F
(8°C) of setpoint, the audible alarm will stop, but the cook switches remain locked and the display
alarm continues flashing. All functions return when the frypot temperature is within 15°F (8°C) of
the programmed setpoint.
Probe Failure Indication
If the temperature probe fails, the display will flash PROBE FAILURE and an audible alarm will
sound. To cancel the alarm, turn the computer OFF. In split-vat fryers, turn off the side in which the
failure occurred. If a probe fails during the high-limit test, PROBE FAILURE is displayed.
NOTE: If the temperature probe fails in the left side of a split-vat, that side cannot be turned back
ON once it has been turned OFF.

3–5

Recovery Out of Range (REC LOC)
Recovery time is an indication of the condition of the fryer. When the fryer is first turned on, the
computer records the amount of time it takes to heat the cooking oil from 250°F (121°C) to 300°F
(149°C). Also, anytime the temperature of the oil drops below 180°F (82°C), such as when cold oil is
added, the computer will check the recovery time. If the fryer takes longer than 1 minute and 40
seconds to recover, the display will show REC LOC and the computer will lock out.
To clear the REC LOC condition, enter the program mode (see How to Enter the Program Mode in
on page 3-10) and push the temperature check switch
(see diagram below).
It is easy to view the currently recorded recovery time with the computer ON. Press the recovery
recall switch
for the frypot you wish to check. On full-vat units, press the right switch.
If REC LOC occurs three or more times within a week, verify that oil is not being added while the
fryer is heating (that is, while a heat mode indicator is illuminated) and that the fryer’s power cord
is fully plugged in. If oil is not being added while the fryer is heating, and the power cord is fully
plugged in, have the fryer checked by a qualified service agent.

Equipment Setup and Shutdown Procedures

Setup
WARNING
Fill the frypot to the bottom oil level line with vegetable oil before pressing the power
switch to the ON position. Failure to do so could damage the frypot.
Fill the frypot with vegetable oil to the bottom OIL LEVEL line located on the rear of the frypot. This
will allow for oil expansion as heat is applied. Do not fill cold oil any higher than the bottom line;
overflow may occur as heat expands the oil.
Ensure that the power cord(s) is/are plugged into the appropriate receptacle(s). Verify that the face of
the plug is flush with the outlet plate, with no portion of the prongs visible.
Set the thermostat knob to the desired frying temperature.
Ensure that the vegetable oil level is at the top OIL LEVEL line when it is at its intended cooking
temperature. It may be necessary to add vegetable oil to bring it up to the proper level.
Shutdown
1. Press the POWER switch to the OFF position (the POWER light will go out).
2. Filter vegetable oil and clean fryers.
3. Place the frypot covers on the frypots.

4.2

Introduction to the Analog Controller

The analog controller, illustrated on the following page, is used to adjust and maintain vegetable oil at
the temperature indicated by the thermostat knob. The fryer has two built-in high-limit protection
features. If the temperature in the frypot reaches approximately 410° F (210° C), the computer opens
the heat relay circuit, turning the elements off. If the temperature in the frypot reaches 450° F (232° C),
a mechanical high-limit shuts off electrical power to the elements. The operator should periodically
test each of the high-limit protection features to verify that they are operating correctly. Refer to page
4-3, Analog Controller High-Limit Check, or the Grills/Fryers Maintenance Requirement Card (MRC)
15 for the procedure.
The analog controller has no timing features. Shake, pull, and QA (hold) times must be monitored by
the operator.

Analog Controller Operating Instructions
WARNING
Before pressing the power switch to the ON position, ensure that the frypot is
properly filled with vegetable oil. See Section 4.1.

1. Verify that the thermostat knob is set to the desired cooking temperature. For split-vat units, set
both knobs.
2. Press the power switch to the ON position. The POWER light will illuminate. For split-vat units,
both power switches must be placed in the ON position if both vats are to be used.
3. If the frypot temperature is below 180° F (82° C), the controller will automatically enter a warm-up
cycle (often called a melt cycle). The heating elements will cycle on and off repeatedly, allowing
the vegetable oil to heat gradually, without scorching. During the warm-up cycle, the heating
mode light will alternately illuminate and go off as the elements cycle on and off. Within about 45
minutes, the controller will exit the warm-up cycle and the heating mode light will remain
continuously illuminated.
4. When the vegetable oil temperature reaches the thermostat knob setpoint, the elements will cycle
OFF and the heating mode light will go off, indicating that the fryer is ready for the cooking
process to begin.

Analog Controller High-Limit Check

Tools needed: Maple Paddle
Note: Conduct this test when fryer will not be needed for about one hour, and when the vegetable oil
is due to be changed. Discard the vegetable oil after completing this check

Note: Check high-limit on only one vat at a time.
CAUTION
Grease filters must be in place and exhaust fans MUST be ON during entire high-limit
control-check procedure.
1. The vegetable oil should be at the normal/shortening level line. Add vegetable oil if necessary.
2. Remove the computer probe from the probe holder and replace it with fry vat probe.
3. Turn the vat power switch to “ON” and set thermostat knob to its highest setting, and wait for
heating light to go OFF.

4-3

Note: You must agitate vegetable oil during the entire high-limit control-check procedure with a
maple paddle.
CAUTION
If after completing both high-limit tests you find only the second high-limit operates
properly, the vat can be used if it is absolutely necessary, but with extreme care. The
controller must be replaced immediately after this period of necessity. If the second
high-limit does not work the vat must not be used until the second high-limit has been
replaced. If the first high-limit feature activates at less than 400°F (204°C), do not
replace the controller unless it interferes with proper cooking. If the second high-limit
activates at less than 425°F (218°C), do not replace it unless it prevents you from
checking the first high-limit feature.
4. Press and hold "first high-limit" position of the vat high-limit test switch.

Result: Electrical element or gas burner turns OFF and "TROUBLE" light comes ON. Vegetable oil
temperature should be between 400º and 425ºF (204º and 218ºC).
5. Press and hold "second high-limit" position of the vat high-limit test switch.

Note: When the trouble light comes ON, or the temperature exceeds 425ºF (218ºC), release switch.
Result: Electrical elements or gas burner turns OFF and the second high-limit will come ON. The
vegetable oil temperature should be between 425º and 450ºF (218º and 232ºC).
CAUTION
When the second high-limit light comes on, or the temperature exceeds 450°F (232°C),
release switch.

6. Turn the power switch to the “OFF” position. One vat must remain ON to ensure hood fan
remains ON.
7. Remove the fry vat probe and reinstall the computer probe into the vat.
8. Allow vegetable oil to cool for one hour before discarding. See statement on discarding oil
(Chapter 5).

Note: Hot oil must not be transported until it cools to 100°F (38°C) or less.
High-Limit check is complete. Repeat procedure for each remaining vat.

frypot in the battery. Remember, only one
frypot can be filtered at a time.

8.2 CARE AND CLEANING OF YOUR FRYER AND FILTER SYSTEM
CAUTION: Never operate the fryer or filter system without vegetable oil in the system.
1. Filter vegetable oil as often as needed. If a heavy volume of breaded food is fried, filter as
often as every hour. Filtering often increases the life of the vegetable oil and produces a
better-tasting product. The best rule to follow is to "filter before you think it is needed".
Even with a product such as french fries, you should filter two to three times per day for best
results.
2. Periodically clean the frypot. Cleaning the frypot, combined with disposing of old vegetable
oil enhances the flavor of the food product. After the fryer is empty, drain the frypot and
close the drain valve. Fill the frypot to the OIL LEVEL line (or the bottom line for fryers
equipped with two oil-level lines) with water and the correct amount of McD All Purpose
Concentrate (APC) Cleaner HSC. Place the baskets into the frypot and bring the solution
to a simmer at 195° F (90.5° C) for 1 hour. Turn OFF the fryer, drain the solution and wipe
the frypot clean and dry.
NOTE: Do not drain water into the filter pan. Water will damage the filter pump enough to
require replacement. Use a stockpot or bucket.
3. The filter pan and filter base assembly must be cleaned on initial start-up and periodically
thereafter.
a. To clean the filter pan, lift pan from the filter base. Take the filter pan to a sink filled
with warm water and grease-cutting detergent.
b. Scrub the filter pan with the frypot brush shipped with the fryer.
c. Rinse the filter pan thoroughly to remove the detergent. Wipe dry with a clean, dry cloth
or paper towels.

5-10

d. To clean the filter base assembly, use a sponge or cloth soaked with a water and greasecutting solution. Be careful not to get water on the pump/motor assembly.
e. Wipe filter-base assembly dry with a clean, dry cloth or paper-towel.
CAUTION
All water MUST be removed from the suction tube before inserting filter pan.

f. Wipe the inside and outside of the tube with clean, dry cloths or paper towels.
g. Insert filter pan into the filter base assembly.
NOTE: To drain old oil or boil-out solution, drain in an appropriate container. DO NOT DRAIN
WATER IN THE FILTER PAN.

WARNING
The filter pan MUST never be used to dispose of, or transport spent-cooking
oil/shortening to the disposal area. Cooking oil /shortening MUST always be
allowed to cool below 100°F (38°C) before transporting to the disposal area. A
shortening disposal unit (MSDU) is available and highly recommended for safety.

5-11

CAUTION
Statement on discarding oil: Hot cooking-oil is dangerous and will cause severe
burns. Handle with extreme caution. When discarding old cooking oil, drain from
the fryer into a Vegetable Oil Disposal Unit (MSDU50) - available from your local
distributor. The disposal unit should be taken to the disposal site and the old
cooking oil pumped into the grease storage container for proper disposal.

Troubleshooting

This section provides an easy reference guide to some of the common problems that may occur during
the operation of this equipment. The troubleshooting guides that follow are intended to help correct,
or at least accurately diagnose, problems with this equipment. Although the chapter covers the most
common problems reported, you may encounter problems that are not covered. In such instances, the
Frymaster Technical Services staff will make every effort to help you identify and resolve the
problem.
When troubleshooting a problem, always use a process of elimination starting with the simplest
solution and working through to the most complex. Never overlook the obvious – anyone can forget
to plug in a cord or fail to close a valve completely. Most importantly, always try to establish a clear
idea of why a problem has occurred. Part of any corrective action involves taking steps to ensure that
it doesn’t happen again. If a controller malfunctions because of a poor connection, check all other
connections, too. If a fuse continues to blow, find out why. Always keep in mind that failure of a
small component may often be indicative of potential failure or incorrect functioning of a more
important component or system.

Before calling a service agent or the Frymaster HOTLINE (1-800-24FRYER):
•
•
•

Verify that electrical cords are securely plugged in.
Verify that circuit breakers are on.
Verify that frypot drain valves are fully closed.

DANGER
Never attempt to move a fryer containing hot cooking oil or to transfer hot cooking oil
from one container to another.
DANGER
Use extreme care when testing electrical circuits. Live circuits will be exposed.
WARNING
Inspection, testing, and repair of electrical equipment should be performed only by
qualified service personnel. The equipment should be unplugged when servicing,
except when electrical tests are required.

7-10: BUILT-IN FILTER SYSTEM SERVICE PROCEDURES
Filtration Problem Resolution
One of the most common errors is placing the filter paper on the bottom of the filter pan rather than
over the filter screen.
CAUTION
ENSURE THAT FILTER SCREEN IS IN PLACE PRIOR TO FILTER PAPER
PLACEMENT AND FILTER PUMP OPERATION. IMPROPER SCREEN PLACEMENT IS
THE MAJOR CAUSE OF FILTER SYSTEM MALFUNCTION

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation
of the filter paper, and ensure that the correct size is being used. While you are checking the filter
paper, verify that the O-ring on the bottom of the filter pan is present and in good condition. A
missing or worn o-ring allows the pump to take in air and decreases its efficiency.
If the pump motor overheats, the thermal
overload will trip and the motor will not start
until it is reset. If the pump motor does not start,
press the red reset switch (button) located on the
rear of the motor.
If the pump starts after resetting the thermal
overload switch, then something is causing the
motor to overheat. A major cause of overheating
is when several frypots are filtered sequentially at
one time, thus overheating the pump and motor.
Allow the pump motor to cool at least 30 minutes
before resuming operation.
Pump overheating can be caused by:
•

Solidified shortening in the pan or filter
lines,
Or

•

Attempting to filter unheated oil or
shortening.

Cold oil and shortening are more viscous,
causing the pump motor to loadup and overheat.

7-13

7-10: BUILT-IN FILTER SYSTEM SERVICE PROCEDURES (cont.)
If the motor runs but the pump does not, there is
a blockage in the pump. Incorrectly sized or
installed paper/pads will allow food particles and
sediment to pass through the filter pan and into
the pump. When sediment enters the pump, the
gears bind, causing the motor to overload, again
tripping the thermal overload.
Solidified
shortening in the pump will also cause it to seize,
with the same result.

FREEING A SEIZED PUMP
Sediment Particle

Up for reverse

FLOW

A pump seized by debris or hard shortening can
usually be freed by manually moving the gears
with a screwdriver or other instrument.

Down for forward

Disconnect power to the filter system.
Remove the input plumbing from the pump.

Use a screwdriver to manually turn the gears, in which:
•

Turning the pump gears in reverse will release a hard particle.

•

Turning the pump gears forward will push softer objects and solid shortening through the
pump and allow free movement of the gears.

Incorrectly sized or installed paper/pads will also allow food particles and sediment to pass through
and clog the suction tube on the bottom of the filter carriage. Particles large enough to block the
suction tube may indicate that the crumb tray is not being used.
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip
on the suction tube is designed to prevent residual shortening from solidifying in the tube. Heater
strips do not prevent residual shortening from solidifying in the pan.
Blockage removal can be accomplished by forcing the item out with an auger or drain snake.
Compressed air or other pressurized gases should not be used to force out the blockage.
For FootPrint III systems built before October, 1999, all heater tapes are wired directly into the line
VAC source (see wiring diagram, page 7-14). They remain energized as long as the unit is plugged
in. In systems built in October, 1999 and later, oil return line heater tapes have been eliminated. In
these units, the only heater tape used is on the suction tube and pump. This tape is still wired
directly into the line voltage. A pair of vacuum-breaking solenoids is wired into the 24 VAC circuit.
The redesigned FPIII is distinguished from original-design units by the absence of casters on the
filter base assembly. The redesign incorporated an improved oil return system that allows
oil/shortening to drain back to the filter pan when the filter system is turned off, eliminating the need
for most heated oil return components.
