When the power control board (PCB) is energizing the
fan, check for approximately 9 to10 VDC between pin
#2 and pin #3 at CN02 on the terminal block. Check
for approximately 2 VDC between pin #1 and pin #3 at
CN02.
Fresh Food Heater Testing
The fresh food evaporator defrost heater, evaporator
drain pan heater, and icemaker fi ll tube heater are in a
parallel circuit. The heaters are in series with the
bimetal defrost safety thermostat.
Check for a combined resistance of 91 W at CN09 on
the terminal block, between pin #1 and pin #2, when
the defrost safety thermostat is closed. When the fresh
food is in the defrost test mode
1 4 (see Service
Diagnostics ) check for 120 VAC at CN09 on the
terminal block, between pin #1 and pin #2.
Note: Access to the evaporator is necessary to
complete testing of the above components, with
exception of the icemaker fi ll tube heater.
• The resistance value of the defrost heater is
approximately 120 Ohm.
• The resistance value of the drain pan heater is
approximately 440 Ohm.
• The resistance value of the icemaker fi ll tube heater
(referred to as the “PIPE HEATER
ICE WATER” on some schematics) is
approximately 2.6K Ohm.
• The defrost safety thermostat is a bimetal
type which will open at 140°F (60°C) and will
reset at 104°F (40°C)
Freezer Heater Testing
The freezer evaporator defrost heater, suction line
drain pan heater, and the evaporator drain pan/drain
tube heater are in a parallel circuit. The heaters are in
series with the bimetal defrost safety thermostat.
Check for a combined resistance of approximately 38
Ohm at CN07, on the terminal block, between pin #1 and
pin #2.
When the freezer is in defrost test mode 1 4 (see Service
Diagnostics ), check for supply voltage of 120 VAC at
CN07 on the terminal block, between pin #1 and pin #2.
Note: Access to the evaporator is necessary to complete
testing of the above components, with the exception of
the suction line drain pan heater.
.• The resistance value of the defrost heater is
approximately 44 Ohm.
• The resistance of the suction line drain pan heater
(referred to as the “DRAIN HEATER” on some
schematics) is approximately 1.3K &!.
• The resistance value of the evaporator drain pan and
drain tube heater (referred to as the “SUB HEATER”
on some schematics) is approximately 377 Ohm!.
• The defrost safety thermostat is a bimetal type which
will open at 140°F (60°C) and will reset at 104°F
(40°C).
Freezer Evaporator Assembly
The freezer evaporator assembly consists of an
evaporator, defrost and drain heaters, defrost safety
thermostat, thermistor, and fan assembly. All the parts are
available as a complete replacement assembly, or the
components are available individually.
All components are housed together and installed in a
recessed compartment in the freezer ceiling.
To access the freezer evaporator assembly:
1. Remove the ice container shelf, then remove the
icemaker.
2. Remove 4 Phillips-head screws that hold the top air
duct cover in place.
3. Remove auger motor and cube motor connectors from
