Customer Questions and Answers for Temperature Sensor (Thermistor) by Bosch

A replacement temperature sensor (thermistor) that monitors internal temperatures and sends readings to the appliance control board. Restores accurate temperature sensing to help cycles and temperature regulation run correctly. What it does:

• Measures internal temperature and relays readings to the control board so the appliance can adjust heating/cooling cycles.
• Helps ensure proper defrost or cycle timing by providing accurate temperature feedback.
• Common symptoms of a failing sensor: inconsistent temperatures, frequent or short cycling, or temperature-related performance issues.
• Works as a direct replacement for a worn or failed sensor to restore normal temperature monitoring.

• Disconnect power to the appliance before starting any repair to avoid shock or damage.
• Handle the sensor and wiring gently; avoid kinking or pulling the lead and ensure the connector seats fully.
• Installation typically requires access behind panels or inside the compartment—keep fasteners organized and follow the service manual.
