WP3390719 - Whirlpool Dryer Thermal Fuse

This Whirlpool Dryer Thermal Fuse (WP3390719) is a genuine part designed for various Whirlpool brand dryers. It functions by shutting off the burner in a gas dryer or the motor in an electric dryer when the dryer overheats, ensuring the safety and efficiency of your appliance. Commonly known as a "thermal cut-off fuse", "disposable thermal fuse", or simply a "dryer fuse", it is a crucial component for preventing fire hazards and maintaining the dryer's operational integrity. Attached to the exhaust duct of the dryer, its primary role is to act as a fail-safe mechanism in the event of overheating. Symptoms that may indicate a need for replacement include a dryer that won't start, excessive heating, or a dryer that shuts off too quickly. Always check your dryer's model number to confirm compatibility before purchasing.
