The Whirlpool WPW10328492 Range Thermal Fuse is a significant secure component installed in Whirlpool electric ranges. It serves as a passive guardian, keeping your oven safe from overheating and any fire threats. This is how it works. The thermal fuse continuously checks the temperature inside the oven cavity. If the temperature exceeds a safe level, usually due to a malfunction or operator error, the fuse activates an automated shut-off. This cuts electricity to the heating element, limiting future temperature increases and protecting your appliance from damage. The thermal fuse, which is a one-time use device, must be replaced once it has blown. While replacing a thermal fuse is a simple procedure for an experienced appliance technician, the benefits are enormous.
