Consistent with control panel glitches. Documentation notes thermostat faults as a common cause of temperature issues. (Thermador Appliance Repair pros

Part: Temperature control thermostat / control board

Faulty temperature sensor (thermistor) or improper sensor placement

How to Identify: Internal thermostat reading does not align with actual air temperature; sensor loose or touching a cold surface; fridge runs constantly or freezes fresh food unexpectedly. (Thermador Appliance Repair pros

Part: Thermistor (temperature sensor)

Electronic control panel glitch or firmware issue
