DIY Solutions
Clean condenser coils and fans
- Unplug refrigerator and pull it away from wall
- Locate and access condenser coils and condenser fan at rear/bottom
- Vacuum and brush away dust/debris from coils and fan blades
- Ensure fan spins freely and no debris is blocking it
- Push fridge back and power on to test noise
Level the refrigerator and reduce vibration
- Check level side-to-side and front-to-back with a bubble level
- Adjust leveling legs until unit is stable and does not rock
- Ensure refrigerator isn’t touching cabinets or walls which can amplify noise
Defrost fan area to remove ice build-up
- Unplug refrigerator and open doors to allow natural defrost
- Leave freezer door open until ice melts around evaporator fan area
- Once defrosted, power back on and observe humming level

User Suggested Solutions
-
Check if the compressor is running normally. If it is, this humming noise is likely normal operation. If the noise is louder than usual, consider monitoring the temperature and checking for any unusual signs. Ensure the refrigerator is level by adjusting the feet if necessary.
-
Inspect the fan motor for any obstructions or damage. Clean any debris around the fan and ensure it spins freely. If the fan is faulty, replace it with a new one.
-
Check the refrigerator's placement. Ensure it's on a flat surface and adjust the leveling feet if necessary to minimize vibrations. If the noise persists, consider placing sound-dampening pads under the appliance.
