Control Board Troubleshooting
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.
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.
Adjustments of Service Test 7 or Service Test 8 will alter the performance of the unit.
Service Test 7 – FF Performance Adjustment
