If your AC keeps tripping the breaker, do not keep resetting it - that can cause damage or fire risk. Causes include a failing compressor, electrical short, dirty condenser, or a weak breaker. Turn the system off and request a professional electrical and HVAC diagnosis.
Likely causes
| Cause | What's happening |
|---|---|
| Failing compressor | Drawing too much current on startup. |
| Electrical short or fault | Wiring or component fault needs professional inspection. |
| Dirty condenser coil | Makes the system work harder and draw more power. |
| Weak/old breaker | May trip even under normal load. |
- Burning smell at the panel
- Scorch marks
- Repeated immediate trips
If anyone is in danger, or you smell gas, leave the home and call 911 or your utility immediately.
