DIAGNOSTICS & TROUBLESHOOTING
ELECTRONIC CONTROL FEATURES
The electronic control in the refrigerator
controls the temperatures in the refrigerator
and freezer compartments independently.
It delays the operation of the evaporator fan
(optional), pulses the defrost heater, and
monitors the water filter usage. The fan delay
and pulsed defrost features are controlled in
the following manner:
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.
WARNING
Pulsed Defrost Heat - During the defrost
cycle, the heater is energized continuously
for the first 2 minutes. It is then cycled off for
60 seconds, and on for 120 seconds. The on/
off cycle is repeated until the bimetal opens,
or the maximum defrost time (25 minutes) is
reached.
