Took the dryer apart and used an Ohm meter to check all the common failure spots. The thermal fuse showed no continuity so that was it. I ordered a lot of the other common failure parts while I was at it to combine shipping and so that we won't have to wait a few days next time something goes out. Also blew out the dryer vent. I used an electric leaf blower and a towel to make it fit without gaps as our dryer is in the center of the house and the vent pipe is too long to clear with a brush. A lot of lint blew outside so that was where the blockage was that caused the fuse to trip. I guess there's a chance the leaf blower will tear the vent pipe connections apart but so far so good on that.
