Possible Causes
How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker. This is a fire hazard. Turn off the breaker and leave it off until the problem is found.
Steps to check (visual only for homeowners):
- Inspect wiring: With power off, remove furnace panels and look for burnt wires, melted insulation, or wires pinched by sheet metal.
- Smell test: Smell near the blower and inducer motors for burnt odor, which may indicate motor failure.
Electrical testing for shorts and overcurrent should be performed by a licensed technician, who can replace the faulty Daikin motor or control board.
