Bosch 00630873 Appliance Temperature Sensor (NTC)

Appliance Temperature Sensor – Bosch

The Bosch 00630873 temperature sensor (NTC thermistor) monitors the temperature inside the appliance and sends a resistance-based signal to the control board, allowing it to regulate heating elements or cooling systems to maintain the target temperature. When the sensor fails or drifts out of specification, the appliance may overheat, underheat, or display a temperature error code. This direct-replacement temperature sensor restores accurate temperature monitoring and control on compatible Bosch appliances.
