WP8557403 Whirlpool High Limit Dryer Thermostat

High Limit Dryer Thermostat

The High Limit Thermostat is a genuine OEM replacement part that regulates the temperature in various Whirlpool dryers, including models from Whirlpool, Amana, KitchenAid, Maytag, Jenn-Air, Magic Chef, Roper, and Admiral. Additionally, it is compatible with certain products manufactured for Sears-Kenmore and Ikea. This thermostat plays a critical role in preventing the dryer from overheating, which can shorten the appliance's lifespan and elevate the risk of fire. It also helps maintain sufficient heat levels for efficient drying performance. A malfunctioning thermostat might prevent the dryer from starting and may require replacement to ensure continued functionality.

For safety, always unplug the dryer before starting any repair work. The high-limit thermostat and thermistor assembly are situated on the heating element housing, and the thermistor's resistance should measure between 50k and 60K ohms at room temperature. To replace this part, you will need a 5/16th socket or nut driver and a quarter-inch socket or nut driver. This thermostat is specifically designed for durability, yet it may need to be replaced if it becomes damaged or fails.
