8. Once the Program Code has been saved the Programming Mode is exited by closing the Refrigerator door(s).
If the new code is incorrect this process should be repeated after closing the Refrigerator door(s).
The Programming mode can be exited at any time by closing the Refrigerator Door(s).
Defrost Operation:
The Control Board adapts the compressor run time between defrosts to achieve optimum defrost intervals by
monitoring the length of time the defrost heater is on.
After initial power up, defrost interval is 4 hours compressor run time. Defrost occurs immediately after the 4 hours.
Note: Once unit is ready to defrost there is a 4 minute wait time prior to the beginning of the defrost cycle.
Optimum defrost is 15 minutes. Each additional minute the defrost thermostat remains closed, 1 hr. is subtracted
from the previous defrost interval. Each minute the thermostat opens prior to optimum defrost, it extends the next
defrost interval 1 hr. When defrost thermostat opens there is a 4-6 minute drip time before compressor restarts or
Control Board will terminate defrost at 25 minutes if defrost thermostat has not opened and will reset the defrost
interval to the 8 hr. minimum setting.
4 hours of continuous compressor run resets the next defrost interval to 8 hours and will initiate a defrost, if 8 hours
of compressor run time has also occurred.
Forced Defrost Mode:
The forced defrost function is performed using the refrigerator display and keypad. Enter the Forced Defrost Mode
by performing the following sequence of events:
1. Hold the refrigerator door light switch closed.
2. Press the Refrigerator Temperature DOWN /- keypad 3 times consecutively.
