Likely Causes
How to Fix It
1
Unplug the refrigerator and access the compressor compartment at the bottom rear
2
Remove the start relay from the compressor and shake it gently — if it rattles, the internal contacts are broken and it needs replacement
3
Test the start relay with a multimeter for continuity between the appropriate pins
4
Test the overload protector for continuity; it should be closed at room temperature
5
If both the relay and overload are good, test the compressor windings for proper resistance between the start, run, and common terminals
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
