If you hear only clicking every few minutes, the compressor cannot start.

Power cycle
Unplug for 10 minutes, then plug back in. Sometimes a compressor that overheated needs time to cool before restarting.
If the compressor starts after cooling, it may have an intermittent issue.
When to Call a Professional
Contact a qualified technician if:
- Compressor draws excessive current on startup
- Start relay is burned or rattles when shaken
- Compressor windings show abnormal resistance
