Air Door

Run control diagnostics to check the air
door operation in step 6. A 12 volt square
wave is supplied to the air door in a series
of short pulses. It is not possible to obtain a
reliable voltage reading with a VOM. Check
for the air door binding with the cover.
Check the resistance of the air door motor
on the air door connector. The yellow wire
to the red wire should have a resistance
reading of 375 - 425

Ω

. The white wire to

the blue wire should have a resistance
reading of RD 375 - 425

Ω

.

Reversed wiring at the air door or at the
control board will cause the air door to oper-
ate exactly contrary to the needs of the
refrigerator. Verify the air door and cabinet
wiring is correct.

DO NOT DISCONNECT

THE AIR DOOR WHILE THE CYCLE IS IN
PROGRESS.

Look for any kind of mechanical blockage.

COMPONENT

SYMPTOM

TEST PROCEDURE/ACTION

Stuck closed.

Reversed wiring.

Stuck open.

Alarm Reset

The indicator lights and alarm continue to
activate after service has been performed.

Pressing the OVER TEMPERATURE RE-
SET will shut off the audio alarm, but this
does not affect the indicator light the first
time the OVER TEMPERATURE RESET is
pressed. The indicator light will shut off
once the OVER TEMPERATURE RESET is
pressed the second time. The audio alarm
will not sound again for the current condition
that caused the alarm until a new condition
occurs or until a Master Alarm Reset is per-
formed. A Master Alarm Reset can be per-
formed by pressing the POWER (ON/OFF)
twice or by turning the power to the refrig-
erator off and on again. The indicator light
will reactivate after the OVER TEMPERA-
TURE RESET is pressed if the condition
that caused the alarm is still present.

Call Service

Alarm

Both thermistors have failed.

Call service is a visual and audio signal that
alerts the customer that the refrigerator
needs service but only for specific failure
modes, none of which are necessarily re-
lated to performance. Run control diagnos-
tics to check the operation of components.
If a particular component is not operating
properly, see that individual component’s
section.
The alarm needs to be reset. Press the
OVER TEMPERATURE RESET to deacti-
vate the call service indicator (see “Alarm
Reset” section).

Call service indicator only, no audible
alarm.

Evaporator fan motor feedback signal lost.

An over-temp condition occurs for 3 hrs or
more.

Inoperative.

FC = Freezer Compartment
