Every dryer made since the 1980s has a thermal fuse, so unless you're working with an appliance from the 1970s or before then your dryer has one, too. This fuse prevents overheating that can create a fire, so it's truly a necessary part of any dryer. However, this fuse may stop functioning. When that happens, it doesn't always mean the fuse is blown out. How do you know if your dryer's thermal fuse is blown? With a little research and troubleshooting, you can find out in minutes.
