WARNING
To avoid risk of electrical shock that can cause death or severe personal injury, disconnect unit from power before
servicing unless tests require power. Discharge capacitors through a 10,000-ohm resistor before handling. Wires
removed during disassembly must be replaced on correct terminals to ensure proper grounding and polarization.

Note:
The Program Code is located on the Serial Plate on this unit after the word Code.
1. Open the Fresh Food door and hold the Fresh Food door light switch closed while pushing the Freezer
Temperature Down
Key pad 3 times consecutively.
Note:
The 3 Keystrokes must be done consecutively and within 10 seconds.
2. Release the Fresh Food door light switch.
3. The control will display PE to confirm entry into the programming mode.

4. Entry is confirmed by pressing the Freezer Down
key once more.
Note:
All control functions will be turned off (Compressor, Defrost, Evaporator Fan, the damper will
remain in its current position)
5. The control will display the current Program Code. This value should be validated with the Program Code
printed on the unit serial plate.

Note:
If the Program Code is correct, the Programming Mode is exited by closing the Refrigerator door(s).
6. To set the desired Program Code number press the Freezer and Refrigerator UP
keys. The
corresponding digit will be advanced with each key press.
7. Once the desired Program Code is displayed, press the Freezer DOWN
Key until the Program Code
begins flashing indicating it has been saved.
Note:
If you attempt to enter an invalid Program Code the control will not save the new code, but will flash the old
code and this will be displayed. (The unit will NOT run with a Program Code of 00).
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:
Power up
Refrigeration mode will occur unless both the cold control and defrost terminator are open, in that case the
defrost mode will occur for 2 minutes.
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.
Note:
The 3 keystrokes must be consecutive and within 10 seconds.
