Whirlpool 3393834 Dryer Cycling Thermostat Switch

Product Description

The WHIRLPOOL 3393834 is a dryer cycling thermostat switch, a temperature-sensing control component used in residential electric and gas dryers. The cycling thermostat regulates drum air temperature by opening and closing the heating circuit as the dryer operates, preventing overheating and maintaining consistent drying performance. It is typically mounted on the exhaust duct or burner housing inside the dryer cabinet. Installation and replacement are performed by appliance service technicians or qualified trade professionals during a standard dryer service call.

This cycling thermostat switch is designed for residential dryer applications. It is positioned in the airflow path to monitor exhaust temperatures and cycle the heating element or gas burner on and off as needed. Units requiring this switch are typically accessed by removing the dryer back panel or front bulkhead, depending on the specific dryer configuration.
