Possible Causes
Failed ambient thermistor, Sensor dislodged from grille area, Damaged sensor wiring, Poor connection at control board
How to Fix / Troubleshooting
Safety: Turn off power at the breaker before accessing the grille or control area.
- Locate ambient sensor: On many Wolf wine coolers, the ambient sensor is near the top grille or behind the toe kick, sensing room temperature.
- Inspect sensor and harness: Ensure the sensor is not dangling or touching hot components. Check for cuts or abrasions in the wiring.
- Reseat connector: Follow the harness to the main control board and reseat the plug.
- Test resistance: Measure sensor resistance at room temperature and compare to Wolf’s thermistor chart. Replace if out of range.
- Reposition sensor: Make sure the sensor is placed where it can accurately sense room air, not trapped behind insulation or metal panels.
