Possible Causes
How to Fix / Troubleshooting
Electrical safety warning: Do not repeatedly reset a breaker that trips. This can cause wiring damage or fire.
Homeowner checks:
- 1. Note when it trips: Does it trip at startup, during blower operation, or randomly? Share this with your technician.
- 2. Inspect visible wiring: With power off, look for rubbed, pinched, or burned wires in the blower and burner compartments.
When to call a professional: An HVAC technician should measure motor currents, inspect wiring, and verify breaker sizing for your Philco furnace. They may replace the blower motor, inducer, or control board.
