How to test evaporator fan motor for continuity.

As you probably know fan motors can be designed for several different purposes most common of these are single phase motors. Is the fan motor noisy while operating. If the continuity test is negative the component has failed and will need to be replaced. Set the fan on a benchtop and locate the two power terminals which is where the wires connect to the fan coil.

Conducting a continuity test on an evaporator fan to conduct a continuity test you need a multimeter set to measure resistance in the 1 ohm ω to 100 ω range. If your freezer isn t as cold as it should be there might be a problem with your evaporator fan motor. This guide will hopefully make testing fan motors for you easy regardless of your experience level or type of fan motor that you are testing. Does the fan blade turn freely.

If the answer is no to the two following questions replace the evaporator fan motor. As the name implies a multitester is a diagnostic tool that can test for several different electrical issues. To test the evaporator fan motor in your freezer open the door and feel for cold air. Use a multimeter to confirm that there is a continuous electrical path present in the motor.
