Likely Causes
How to Fix It
1
Pull the refrigerator away from the wall and clean the condenser coils thoroughly with a coil brush and vacuum
2
Ensure there is at least 1 inch of clearance on all sides for proper ventilation
3
Check the condenser fan near the compressor; it should run whenever the compressor runs; replace if it does not spin
4
Test the compressor start relay by removing it from the compressor and shaking it; a rattle indicates it is broken
5
If the coils are clean, the fan works, and the relay is good, the compressor may be failing and professional refrigerant service is needed
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
