Freezer Recovery Mode
There is a program on the main control system for the
product to limit or stop the flow of refrigerant to the
ice maker. This allows the freezer evaporator to get
as much refrigerant as is needed to maintain product
temperature. If refrigerator is in a defrost cycle, the
main control board will stop the fl ow of refrigerant to the
ice maker for 20 minutes after the product comes out of
defrost to allow the freezer evaporator temperature to
recover from the defrost cycle. The compressor does not
run during defrost so there will be no fl ow of refrigerant
to ice maker during defrost. If the temperature in the
freezer is 8°F above freezer set point, the lower control
board will stop ice maker operation. Once the freezer
temperature drops to 4°F above the set point, the lower
control board will allow the ice maker to resume making
ice cubes.
Example: Freezer is set at +2°F, and freezer
temperature rises above 10°F.
The lower control board will stop ice making operations
and only allow enough refrigerant to fl ow to ice maker
compartment to maintain temperature to prevent ice
melt. Once freezer temperature recovers to +6°F, ice
maker will resume normal operation.

he icemaker control will display error codes for certain
