Possible Causes
Faulty mechanical thermostat contacts, Failed electronic control board, Broken wiring between thermostat/control and compressor, Open safety thermal fuse in control circuit
How to Fix / Troubleshooting
Safety: Unplug before testing continuity or bypassing controls.
Steps:
- Mechanical thermostat: Remove the thermostat knob and cover. Test continuity across the thermostat terminals when set to cold. If open when it should be closed, replace the thermostat.
- Electronic control: For digital models, check if the display responds and allows temperature changes. If the display is dead but light works, the control board may have failed.
- Wiring check: Inspect wiring from the control to the compressor relay for breaks or loose connectors. Repair as needed.
- Thermal fuse: Some Sharp models include a thermal fuse in the control circuit. Test for continuity and replace if open.
