How to Fix / Troubleshooting
Safety first: Unplug immediately and do not continue using the appliance until the source is identified. Risk of fire exists.
Steps to investigate:
- External inspection: Look for discoloration or melting around vents, power cord entry, and control panel.
- Open housing: With the unit unplugged and cool, remove covers to inspect the main PCB, heater connections, and fan motor.
- Check connectors: Look for browned or melted plastic around spade terminals and connectors. Replace any burnt wiring harnesses and terminals, and correct loose connections.
- Inspect PCB: Identify any burnt components or darkened areas on the main control board. Replace the main control board if damage is present.
- Fan motor: If the smell is strongest near the fan, the motor windings may be overheating. Replace the circulation fan motor.
