Bosch High Limit Thermostat 00422272 OEM Part

The High Limit Thermostat for dryers, calibrated at 175 degrees, serves as an Original Equipment Manufacturer (OEM) temperature limiter for select Bosch vented dryer models, including those from Thermador and Gaggenau. Its primary function is to regulate airflow temperature, effectively preventing potential overheating scenarios.

This component incorporates heat-treated alloy links that disrupt electrical circuits if temperatures surpass designated thresholds. The enclosing housing safeguards the internal mechanisms from moisture, ensuring precise operation.

Prolonged exposure can compromise the integral trigger components, extending cooling cycles. Physical harm may also impair the unit’s protective abilities.

Indicators of a malfunctioning temperature limiter include:

- Failure to detect or react to excessive exhaust temperatures
- Interrupted cool-down periods due to non-responsive safety triggers
- Continuous activation of heating elements lacking proper regulation

This replacement limiter is compatible with certain models of Bosch, Thermador, Gaggenau, and Kenmore dryers, reinstating critical safety features upon accurate installation.
