The High Limit Thermal Fuse is an OEM replacement part for Whirlpool dryers that prevents overheating. It is a one-time use use part that must be replaced if it is tripped. Its designed to respond to excessively high temperatures, safeguarding both the appliance and the home.

Causes of a bad High Limit Thermal Fuse can include blocked ventilation in the dryer or exhaust vent, overloading the dryer, or component failure within the heating system leading to overheating.  

Symptoms of a bad High Limit Thermal Fuse include:

• The dryer not starting or abruptly stopping during a cycle.
• No heat being produced during cycles, leading to damp clothes.
• A blown thermal fuse detected during a continuity test.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
 

This cycling thermostat regulates your dryer's internal air temperature by switching the heat source on and off, helping prevent overheating and keeping drying performance consistent. Replace it if temperatures are erratic, items run too hot, or dry times increase. What it does:

• Monitors drum air temperature and opens/closes to control the heater
• Maintains stable temperatures across fabric/temperature settings
• Failure symptoms include no or low heat, overheating/scorch smells, long dry times, or inconsistent cycling
• Helps protect against damage from excessive heat when functioning correctly

• 1 cycling thermostat

• Disconnect power; if it's a gas dryer, also shut off the gas supply
• Allow the unit to cool; access the thermostat (typically on an internal air duct or blower housing); note wire positions
• Transfer wires to the new thermostat one at a time; mount flush against the metal surface; do not overtighten
• After installation, clean lint passages and ensure proper airflow and temperature control
