Unit hums but does not start cooling; compressor is hot to the touch.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

Possible Causes

Failed start relay, weak compressor, low line voltage, seized compressor

Safety First: Turn off power and allow the compressor to cool before handling components.

Check voltage: Verify correct line voltage at the outlet. Low voltage can prevent compressor start.
Inspect start device: Remove and inspect the compressor start relay and overload for damage. Replace if suspect.
Restart test: After replacing the start device, restore power and observe. If the compressor still hums and trips, the compressor may be locked and require professional replacement.
