How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker; this is a fire hazard. Turn off the breaker and outdoor disconnect and call a professional if you suspect a short.

Steps to check (visual only):

  • 1. Inspect wiring: With power off, remove the condenser service panel and look for burnt wires, melted insulation, or signs of arcing.
  • 2. Check contactor: Look for welded contacts or burnt areas on the contactor.
  • 3. Smell for burnt odor: A strong burnt smell from the compressor or fan motor area may indicate internal failure.

When to call a professional: Tripping breakers due to shorts or high current require an HVAC technician to test motors, compressor, and wiring with proper instruments.
