How to Fix / Troubleshooting
Critical safety warning: Immediately turn OFF and unplug the unit. Do not continue to operate it until the source is identified.
- 1. Visual inspection: With the unit unplugged, remove the cover and inspect wiring, connectors, and the PCB for burn marks or melted insulation.
- 2. Smell localization: Carefully smell near the fan motor, compressor compartment, and PCB to identify the source (without touching components).
- 3. Check for obstructions: Ensure fan blades are not jammed, causing motor overheating.
