Possible Causes
Failed compressor start relay, Open overload protector, Defective compressor, Control board not sending start signal
How to Fix / Troubleshooting
Safety first: Unplug the unit. Compressor and high-voltage work should be done carefully.
Diagnostic steps:
- Listen for clicks: When starting a cycle, listen for a click from the start relay. No click may indicate a control or relay issue.
- Inspect start components: Access the compressor and remove the start relay and overload. Check for burn marks or rattling.
- Replace start kit: Install a new Tristar compressor start relay and overload protector if the originals appear damaged.
- Control board check: If the compressor still does not start, the main control PCB may not be sending power and may need replacement.
- Compressor failure: If the compressor hums briefly then trips, it may be locked and require professional replacement.
