If your freezer isn t as cold as it should be there might be a problem with your evaporator fan motor.
How to test evaporator fan motor for continuity.
Locate the door switch that s pressed when the door is closed.
Use a multimeter to confirm that there is a continuous electrical path present in the motor.
Is the fan motor noisy while operating.
Does the fan blade turn freely.
If the continuity test is negative the component has failed and will need to be replaced.
It can sometimes be very confusing to test fan motors for people who don t have much experience.
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.
As the name implies a multitester is a diagnostic tool that can test for several different electrical issues.
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.
Set the fan on a benchtop and locate the two power terminals which is where the wires connect to the fan coil.
To test the evaporator fan motor in your freezer open the door and feel for cold air.
Hold this down and listen for the motor starting.
