Product review (5 stars): A very simple and very cheap solution to a very common dryer problem.
If your dryer suddenly doesn't get hot, or doesn't even turn at all, a blown thermal fuse is probably the reason. It's an easy install (once you've gotten around the back of the unit) and much cheaper than hiring a technician. We have a very old but sturdy coin-operated dryer in the basement of one of our rental buildings, and this was all it needed to be fully functional again! Much cheaper than replacing the unit.

Just make sure that you clean out your dryer vent. These fuses typically burn out because too much lint has built up in the exhaust vent behind (or inside of) the dryer, and instead of exhausting hot air, it overheats. If you replace the fuse without ensuring exhaust can flow freely out the back, the new one will burn out as well.
