How To Test Evaporator Fan Motor For Continuity

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.

How to test evaporator fan motor for continuity.

If your freezer isn t as cold as it should be there might be a problem with your evaporator fan motor. As you probably know fan motors can be designed for several different purposes most common of these are single phase motors. Does the fan blade turn freely. To test the evaporator fan motor in your freezer open the door and feel for cold air.

Set the fan on a benchtop and locate the two power terminals which is where the wires connect to the fan coil. Is the fan motor noisy while operating. Hold this down and listen for the motor starting. 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.

Use a multimeter to confirm that there is a continuous electrical path present in the motor. Locate the door switch that s pressed when the door is closed. As the name implies a multitester is a diagnostic tool that can test for several different electrical issues. You can test a system for either ac or dc voltage amperage open circuit or short circuit problems and you can also test to make sure the circuit pathways are intact and continuous known as a continuity test this tool can therefore provide the same function as a.
