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.
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.
