Safety: Unplug the wine cooler before removing interior trim.

Locate upper sensor: In dual-zone Wolf wine coolers, the upper zone sensor is typically behind the upper compartment liner or behind a small plastic cover.
Inspect sensor: Ensure the sensor is intact and firmly mounted. Reclip if loose.
Check wiring: Follow the harness to the top or rear where it connects to the control board. Reseat the connector.
Test sensor: Measure resistance at room temperature and compare to Wolf’s thermistor chart. Replace the sensor if readings are out of spec.
