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. Locate the door switch that s pressed when the door is closed. If the answer is no to the two following questions replace the evaporator fan motor. 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. If your freezer isn t as cold as it should be there might be a problem with your evaporator fan motor. It can sometimes be very confusing to test fan motors for people who don t have much experience.

Does the fan blade turn freely. 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. Use a multimeter to confirm that there is a continuous electrical path present in the motor. As the name implies a multitester is a diagnostic tool that can test for several different electrical issues.
