Step Component tested Comment Results
Freezer Thermistor The board will check the
resistance of the thermistor
and display the results
on the water filter indicator.
Refrigerator The board will check the
Thermistor resistance of the thermistor
and display the results on
the water filter indicator.
Evaporator Fan The control switches neutral to the evaporator fan motor. Confirm
Motor evaporator fan motor is running and operating correctly.
Compressor and Line voltage is switched to the components. Confirm components are
Condenser Fan Motor running and operating correctly.
Air Baffle Motor The control switches neutral to the baffle motor. The baffle motor
continues to run until advanced to step 6. Confirm that the evaporator
fan motor is running and the air baffle is opening and closing.
Defrost Heater and Line voltage is switched to the heater circuit. Confirm that the heater is
Bi-metal operating.
NOTE: If the bi-metal is open, it will be necessary to by pass it with an
insulated jumper.
