Customer Questions and Answers for Temperature Regulator by Bosch

The Temperature regulator is an OEM replacement part for Bosch dryers. It is a temperature-sensitive resistor located inside the dryer cabinet that monitors air temperatures throughout drying cycles. The thermistor provides continuous feedback to the control board.

Causes of a faulty thermistor tend to involve gradual sensor drift or physical damage due to extensive exposure to moisture fluctuations and mechanical vibrations inside the drum. Mineral scale buildup could also interfere with resistance readings over time.

Symptoms comprise:

• Inability for the temperature regulator to accurately detect sleeve air temperature
• Fluctuating or inconsistent drying temperatures between loads
• Thermal runaway triggering high-limit cut-offs or error codes
• Prolonged drying times stemming from control faults

This OEM Bosch part is also compatible with Thermador, Gaggenau and some Kenmore models.
