How to Fix / Troubleshooting
Immediate safety: Unplug the wine cooler immediately if you smell burning or see smoke. Do not continue to operate the unit.
- Visual inspection: After the unit cools, remove the rear panel and inspect the main control board, compressor area, and wiring for burn marks or melted insulation.
- Check wiring harness: Look for wires touching hot compressor surfaces or sharp metal edges. Repair or replace damaged harnesses with the correct hOmeLabs wiring harness.
- Inspect main board: If any components on the board are charred or cracked, replace the main control board.
- Compressor check: If the compressor shell is discolored or there is oil leakage, the compressor may be failing and should be evaluated by a professional.
- Do not reuse damaged parts: Any overheated or melted components must be replaced before the unit is powered again.
