A thermal fuse is a small device that is used to protect your dryer from overheating. If the thermal fuse is bad, it can cause your dryer to overheat and catch fire. You should check the thermal fuse on your dryer regularly to make sure it is not damaged or broken.
To check the thermal fuse, first unplug your dryer from the wall outlet. Then, remove the back panel of the dryer so you can access the fuse. Once you have accessed the fuse, use a multimeter to test it for continuity. If there is no continuity, then the fuse is bad and needs to be replaced.
If you have a gas dryer, you will also need to check the gas valve coils. To do this, remove the back panel of the dryer and locate the gas valve coils. Once you have located the coils, use a multimeter to test them for continuity. If there is no continuity, then the coils are bad and need to be replaced.
It is also a good idea to clean your dryer vent regularly. A clogged dryer vent can cause your dryer to overheat and catch fire. To clean your dryer vent, disconnect it from the dryer and vacuum it out with a brush attachment.
If you find that your dryer thermal fuse is bad, or if you suspect that it may be damaged, you should replace it immediately. A new thermal fuse can be found at most hardware stores. It is recommended that you replace the thermal fuse every three to five years to prevent your dryer from overheating and catching fire.
