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.

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.
Note
: When energy switch is in the “Off” position the fresh food mullion heater is energized and when the
energy switch is in the “On” position the fresh food mullion heater is not powered. To avoid moisture from
condensing on the fresh food mullion the energy switch should always be in the “Off” position.
This test also allows observation and measurement of proper defrost function. You can observe defrost heat and voltages
while the test is activated.

Service Test 2 – Compressor/Condenser Fan Test
When selected and activated this test will operate the Compressor/Condenser Fan circuit. You should evaluate proper
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 3 – Evaporator/Freezer Fan Test
When selected and activated this test will operate the freezer fan. The Refrigerator Up
key will toggle between “O” /
“F” (ON & OFF) the fan drive circuit. You will have to inspect the fan for proper function. The test must be “deactivated” or
in the OFF position to move to another test selection.

Note:
In the event of excessive moisture on fresh food door mullion. The red and blue cabinet wires to door
harness can be reversed to power fresh food door mullion heater continuously. This will help to reduce
moisture on fresh food door mullion. See wiring alternate above for wiring in mullion heater for continuous
operation. When powered continuously Energy Switch is no longer in heater circuit.
