You want to do a few things to correct this. First make sure your air flow is good. then replace the cycling thermostat. That stat is mounted on the blower housing right next to the fuse:
I recently worked on a
dryer that was doing this exact thing and I replaced the control thermostat.
My friend Larry brought it by because it was overheating and he had already changed the fuse once.
I always see the tough or the strange. LOL. Anyway I took the
dryer completely apart and cleaned it up real good. Replaced the fuse and observed the
dryer with the back off. I watched the heating element and it just stayed on way too long. Normally you can hear the control clicking and observ the element coming on and off. The cycling thermostat has 4 wires. 2 small wires and 2 large wires. The large wires carry the current to the heater element. The 2 small wires are use to warm up the klixon so that it will shut down even faster for knits and perma press items. So what goes wrong? The bimetal inside the control simply gets fatigued and don't shut down no more. The dryer overheats and the fuse blows.
