How to Fix / Troubleshooting

Safety: If you smell burning plastic or see smoke, turn the unit off immediately, unplug it, and do not use it until inspected. Fire risk is present.

Steps:

  • 1. Visual inspection: With the unit unplugged, remove covers and inspect the PCB, wiring, and motors for burn marks, melted insulation, or discoloration.
  • 2. Check connections: Tighten any loose spade connectors or terminal screws. Replace any burnt connectors and the associated wiring harness.
  • 3. Motor check: If the smell is strongest near a fan motor, check for overheating, noise, or stiff rotation. Replace the motor if suspect.
  • 4. Capacitor and PCB: Inspect capacitors for bulging or leaking and the PCB for burnt components. Replace any damaged parts.
  • 5. Test cautiously: After repairs, run the unit under supervision. If odor persists, discontinue use and consult a technician.
