How to Test Your AC Fan Motor
- Check the power. If you suspect the fan motor is bad, the first thing you should check is the power to the motor and the power to the air conditioning unit.
- Check the windings. Next, check the windings of the fan motor for an open or a short.
- Inspect the capacitor.
Can a refrigerator work without the fan?
The evaporator fan is responsible for circulating the cold air from your coils and into the refrigerator section. Without it working, the cool air will not be efficiently blown onto your fresh food. However, your refrigerator will still try to maintain that temperature by instead just running all the time.
How do you diagnose a bad evaporator fan motor?
Listen for a squeal or chirp sound. If the evaporator fan motor is going bad, it may still run while making a high pitched sound that may come and go. If you hear that sort of sound, something may be caught in the fan blades or the motor may be dying.
How many ohms should a refrigerator fan have?
If you get a low resistance reading, which is anything less than about 100 Ω, the charge generated by the tester is circulating normally and the coil is good.
How do you test an evaporator fan motor on a freezer?
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. Locate the door switch that’s pressed when the door is closed. Hold this down and listen for the motor starting.
How do you test the fan on a whirlpool refrigerator?
If the fan blades turn freely, unscrew the bracket holding the fan to the freezer wall and pull the electrical harness apart. Remove the fan and inspect the bushings on both sides to make sure they aren’t worn. To conduct a continuity test, you need a multimeter set to measure resistance in the 1-ohm (Ω) to 100-Ω range.
How to test a refrigerator fan with a multimeter?
If the blades spin freely, remove the fan from the fridge and get your multimeter out. Step 3 – This is called a continuity test and you need to set the multimeter to the dial that says 1 to 100 ohms and then put the two leads on the appropriate terminals.
What should I do if my Refrigerator evaporator fan motor is bad?
If it turns out the evaporator fan motor is fine, you may want to consult a certified refrigerator repair professional to help determine what the problem is. Remember that it will take a little while for the freezer to get cold again once you plug it back in.
