Electronic Temperature Control Operation, continued
Freezer Automatic Defrost
The control also monitors compressor total running time and
will enter a defrost cycle after total compressor running time is
greater than 4-hours since the last defrost cycle OR if evaporator
coil temperature drops below -30ºF (-34ºC) (indicating excessive
frost on the coil.)
Freezer Manual Defrost
If a manual defrost is desired, simply unplug the unit for several
seconds, then plug unit back in. This will cause the control to
re-initialize and then enter a defrost cycle.
When the control enters the defrost mode, it switches off the
evaporator fan motor, compressor and condenser fan motor,
and switches on the defrost heater to warm the evaporator
coil. Thereby melting all frost accumulated during the previous
refrigeration cycle. The digital temperature display will now read
dEF. The control will continue the defrost cycle for a MINIMUM
of 8 minutes and a MAXIMUM of 30 minutes depending on the
amount of frost accumulated on the evaporator coil.
After the defrost cycle is complete, the control returns to a normal
refrigeration cycle, however the evaporator fan motor will not
switch on for 2 minutes AFTER the compressor and condenser
fan motor have begun operating. The digital temperature display
will continue to read dEF until the evaporator has returned to
normal freezing temperatures (up to 30 minutes).
Dual Temperature Refrigerator/Freezer Cabinets
These units combine both a refrigerator compartment and a
freezer compartment in the same cabinet. Each compartment has
its own separate refrigeration unit and Electronic Temperature
Control.
Regarding Single Section Dual Temperature Units:
After initializing, the both controls will immediately
enter a DEFROST mode and the displays will read
DEF. The compressor and condenser fan as well as
the evaporator fan will remain off until initialization
defrost is complete. This initial defrost cycle may
take up to 15 minutes to complete, at which time
the freezing cycle will begin. The displays will
continue to read DEF for an additional 30 minutes
before displaying temperature.
Service Alert
During normal operation the evaporator fan may cycle
and/or pulse independently of the compressor. Consult
the service manual or contact Technical Support at
1-800-733-8829 if you are unsure of the proper function.
