How to Fix / Troubleshooting
Safety first: Immediately turn OFF power at the breaker and do not operate the furnace until inspected. Risk of fire exists.
- Visual inspection: After cooling, remove access panels and look for burned wires, melted insulation, or scorched components.
- Check blower motor: Smell near the blower housing. A strong hot electrical odor may indicate a failing motor.
