Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit. Avoid touching bare compressor terminals.
Inspect start components:
- Access the compressor and remove the start relay/overload assembly.
- Check for burn marks, melted plastic, or rattling pieces inside the relay.
- Ensure all terminal connections are tight and corrosion-free.
Replace suspect parts:
- Install a new, compatible start relay and overload protector.
If the compressor still does not start, the control board may not be sending power or the compressor windings may be open. These conditions require professional diagnosis.
