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:

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.

Service Test 1 – Defrost Thermostat & Defrost Circuit Test

When selected this test will display the state of the defrost thermostat. In order to perform this test the defrost heater will

be energized. The test is activated and deactivated using the Refrigerator Up key. Once activated, this test must be

de-activated to move to another test number. The Freezer Up / Down keys allow selection of the test to be

performed.

This test also allows observation and measurement of proper defrost function. You can observe defrost heat and voltages

while the test is activated.

operation of the compressor and condenser fan. The Refrigerator Up key will toggle between “O” / “F” (ON & OFF)

the compressor drive circuit. The test must be “deactivated” or in the OFF position to move to another test selection.

Service Test 6 – Open Damper Test

When selected this test will indicate the current position “O” / “C” (OPEN / CLOSED) of the refrigerator damper. The

Refrigerator Up key will toggle the damper open and closed. You must allow 1 minute for each attempt to change

the damper position. You should observe proper damper function.

This test will allow the adjustment of the control performance points. Each step will incrementally change the Freezer

performance warmer 1° (towards 1) or colder 1° towards (9) as adjusted. The default value is 5.
