What is a thermal fuse?
According to SWE, a thermal fuse is a component that serves as a safety device. This is also known as thermal shutdown. It opens the circuits to prevent overheating. Thermal fuses are designed to detect heat generated by an overcurrent in an electrical system. The cause of an overcurrent can be a component failure or a short circuit.
How do I replace the thermal fuse?
After testing the thermal fuse, as recommended, a blown fuse is not too difficult to replace, depending on the type of unit it is in. In most cases, the back panel of the dryer must be removed. The fuse is usually located behind the rear panel. It is always advisable to consult the user’s manual for the exact setting of the thermal fuse. Sometimes it is located on top of the dryer. If you don’t have a paper manual, you can usually find one online. Simply remove the old blown fuse and replace it with a compatible model.
How to check if a thermal fuse is working?
According to Hunker, you should use a multimeter to check the thermal fuse. Just make contact between the right side of the device cable and the right side of the fuse. You must also repeat the procedure on the left wire of the multimeter. If the needle moves, the fuse is still working. If the needle does not move, it can be assumed that the fuse has blown and must be replaced. Many devices that work with thermal fuses stop working when the fuse burns out. If there are no other malfunctions or problems with the unit, replacing the fuse will allow the unit to operate properly again.
How much does a thermal fuse cost?

Is the thermal fuse the same as an electrical fuse?
When the fuse blows, the power is cut off or shut off to prevent the circuit from overheating. This is also how a conventional fuse works. The main difference between the two is that once a fuse blows, it is no longer usable. While a conventional fuse resets itself, the thermal fuse does not and must be replaced immediately. The same applies if the thermal switch fails. It is not designed to be reset like other types of fuses. The second difference is that the thermal fuse only reacts when there is an excess of heat over the overcurrent. The overcurrent must be high enough to cause excessive heat, which can be detected by the thermal fuse. The heat heats the thermal fuse and triggers a reaction that ensures safety against electrical fires.
Why do thermal fuses not reset?
Thermal fuses do not reset themselves when the temperature drops like a circuit breaker would. A thermal fuse must be replaced when it fails or is triggered.
Do thermal fuses react to current?
Unlike electrical fuses or circuit breakers, thermal fuses only react to excessive temperature, not excessive current, unless the excessive current is sufficient to cause the thermal fuse itself to heat up to the trigger temperature. Shop our range of Thermal Fuses.
What is a thermal fuse?
Thermal fuses are used in any appliance where overheating presents an immediate danger. Blow dryers and clothes dryers are two of the most common uses for thermal fuses.
