Why would my thermal fuse keep blowing

I would look into a venting issue, make sure it's clean. How is your vent run? How long? What is the venting material?

Have you cleaned out every part in your drier that moves air? This includes the blower fan, the air ducts, and the housing for the elements. You have to remove them from the drier and wash them out because the lint hardens on like concrete. After that check your venting to make sure it's as short as possible and clear. It's easy to have two inches of deposits built up over time which will cause a fire. DrTom4444
