Check Evaporator Fan Motor

You can check the evaporator fan motor by removing the plastic breaker strips on the left- and right-hand sides of the freezer section of the fridge.

NOTE: When removing the plastic breaker strips, it is recommended that they be pre-heated using a 40-to-60-watt light bulb. The light bulb is applied to each breaker strip for 5 to 7 minutes, to warm the pieces and make them more pliable and less subject to breakage.

NOTE: On fridges that are equipped with factory-installed icemakers, the icemaker will have to be removed before servicing the evaporator fan motor.

With above parts removed and the fridge plugged in, open the freezer door, and listen for a whirling sound of the fan. If there is no sound, visually check (if visible) the motor and fan blade to see if it is turning. If you cannot see the fan blade turning, check to see if there is an obstructin such as meat wrappers or ice blocking the movement of the fan. Remove the obstruction if detected.

If there is no obstruction, it is possible that the evaporator fan motor is defective. Some fridges have a light inside the freezer that is controlled by a switch that makes or breaks an electrical circuit when the door is opened or closed . Manually push this switch in or out to see now if the evaporator fan motor begins to run. If the motor still does not work, the problem is probably a defective evaporator fan motor.

Before removing the evaporator fan motor, turn the thermostat to the ON position. With the fridge power cord plugged in, make a voltage check with the volt/ohmmeter to determine if electricity is available to the evaporator fan motor. With the volt/ohmmeter set on the 150-volt scale, place the probes of the volt/ohmmeter across the evaporator fan motor terminals. If the required voltage is available, a reading of 110-125 volts will be indicated. If voltage is available, the fan motor should be checked next.

To check the evaporator fan motor with the electrical test cord, remove the unit from the fridge cabinet. Attach leads of the test cord to each terminal of the fan motor. With the test cord plugged into a 110-to-125-volt receptacle, the fan motor should run. If the motor does not run, it must be replaced.

Rather than use the power test cord, you can check the condition of fan motor windings by using the volt/ohmmeter. On the RX-1 scale, place one probe of the volt/ohmmeter on one terminal of the fan motor and the remaining probe of the volt/ohmmeter on the other terminal of the fan motor. The volt/ohmmeter should show a reading of approximately 100 ohms resistance.A higher reading would indicate that the fan motor is defective and will have to be replaced in order for the fridge to operate properly.

Check Condenser Fan Motor

With the fridge power cord plugged in a 110-to-125-volt receptacle and the fridge running, remove the front grill. With your hand, feel for warm air that is being discharged from the condenser fan motor. If there is no air discharge, either the condenser fan motor blade is stuck, there is no voltage to fan motor, or the motor is defective internally.

Unplug the fridge and remove the screws in back of the fridge with hand toolsand check for obstruction; insulation, paper wrappers, debris, etc., that could clog the motor fan blade and cause it to stall. If there is an obstruction, unplug the fridge power cord and remove the debris. If there is no obstruction, turn the motor fan blade by hand. If you feel a slight resistance, the fan motor shaft bearings are frozen. You will have to install a new condenser fan motor for the fridge to operate properly.

To check the condenser fan motor with the electrical test cord, remove the unit from the fridge cabinet. Attach leads of the test cord to the two terminals of the fan motor. With the test cord plugged into a 110-to-125-volt receptacle, the fan motor should run. If the fan motor does not start, then the condenser fan motor is defective, and must be replaced.

A static test of the fan motor winding can be made by using the volt/ohmmeter. Set the volt/- ohmmeter on the RX-1 scale and place one probe of the volt/ohmmeter on one terminal of the fan motor and the remaining probe of the volt/- ohmmeter on the other terminal of the fan motor. The scale of the volt/ohmmeter should show 1 to 10 ohms resistance. A high resistance reading, or no reading at all, would indicate that the fan motor is defective and will have to be replaced.
