How To Test Evaporator Fan Motor For Continuity

If the continuity test is negative the component has failed and will need to be replaced.

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. Set the fan on a benchtop and locate the two power terminals which is where the wires connect to the fan coil. It can sometimes be very confusing to test fan motors for people who don t have much experience. Hold this down and listen for the motor starting.

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. Locate the door switch that s pressed when the door is closed. 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. Is the fan motor noisy while operating.

As you probably know fan motors can be designed for several different purposes most common of these are single phase motors. As the name implies a multitester is a diagnostic tool that can test for several different electrical issues. Use a multimeter to confirm that there is a continuous electrical path present in the motor. If the answer is no to the two following questions replace the evaporator fan motor.
