Refrigerator Making Fan Noise

Quick answer

If your refrigerator is making fan noise, it could be due to a faulty fan motor, blocked vents, or a failing evaporator fan. First, ensure the refrigerator is level and clean the condenser coils. If the noise persists, inspect the fan blades and motor.

Confirm the symptom

• The refrigerator is making a loud humming, buzzing, or rattling noise.
• The noise seems to come from the back or bottom of the refrigerator.
• The noise is constant or occurs intermittently when the refrigerator is running.
• The refrigerator is cooling properly, but the noise is bothersome.

Tools and prep

• Screwdriver (Phillips and flathead)
• Vacuum cleaner with a brush attachment
• Flashlight
• Level
• Safety gloves
• Turn off the refrigerator and unplug it from the power source.
• Ensure the area around the refrigerator is clear for safe access.

Step-by-step troubleshooting

1. Check the Level
   Do: Use a level to check if the refrigerator is balanced.
   Observe: If the refrigerator is not level, adjust the legs until it is.
   Means: An unlevel refrigerator can cause the fan to make noise.
   Next: Check the condenser coils.
2. Clean the Condenser Coils
   Do: Locate the condenser coils, usually at the back or bottom of the refrigerator.
   Observe: Use a vacuum cleaner with a brush attachment to remove dust and debris.
   Means: Dirty coils can cause the fan to work harder and make noise.
   Next: Inspect the fan blades.
3. Inspect the Fan Blades
   Do: Remove the cover to access the fan.
   Observe: Check for any debris or damage to the fan blades.
   Means: Debris or damage can cause the fan to make noise.
   Next: Clean or replace the fan blades if necessary.
4. Test the Fan Motor
   Do: Spin the fan blade manually.
   Observe: If the blade is hard to turn or makes a grinding noise, the motor may be faulty.
   Means: A faulty motor can cause excessive noise.
   Next: Replace the fan motor if necessary.
5. Check the Evaporator Fan
   Do: Locate the evaporator fan, usually behind the freezer wall.
   Observe: Ensure the fan is spinning freely and is not obstructed.
   Means: A blocked or faulty evaporator fan can cause noise.
   Next: Replace the evaporator fan if necessary.
6. Inspect the Compressor
   Do: Listen for noise coming from the compressor.
   Observe: If the noise is coming from the compressor, it may need servicing.
   Means: A faulty compressor can cause loud noises.
   Next: Contact a professional if the compressor is the issue.
