The Whirlpool hi-limit thermostat is an OEM replacement part responsible for regulating the temperature inside the dryer and providing protection against overheating. The L225-40F thermostat is specifically designed for Whirlpool dryers and is located on the heating element housing or the dryer's air duct. It acts as a safety device that monitors the temperature inside the dryer. When the temperature exceeds a certain threshold, the hi-limit thermostat automatically cuts off the power to the heating element, preventing excessive heat buildup and reducing the risk of fire. The Whirlpool hi-limit thermostat can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
