How to Fix / Troubleshooting
Safety: Electrical issues can be hazardous. If you are not comfortable, call an electrician or HVAC technician.
Steps:
- Check furnace switch and plug: Ensure the switch is tight and not arcing. If the furnace is cord-connected, inspect the cord and outlet.
- Inspect breaker: Lightly press on the furnace breaker to ensure it is fully seated. If warm or buzzing, have it replaced.
- Look for loose connections: With power off, inspect the furnace junction box for loose wire nuts or burned wires.
Persistent power interruptions should be evaluated by a licensed electrician to prevent damage to the furnace and home wiring.
