You might want to try replacing the thermister. I just recently had mine go south. Dryer had been acting up, finally got to the point where I had no heat. I assumed it was the thermal fuse, but when I pulled it out, it still ohmed out ok. Checked the thermister on a lark since it was right there and it was reading way off (500kish ohms, should be somewhere around 12k). Had a new one overnighted and swapped. Interesting thing was now the bad thermister was reading ok, so, I think it probably starts to fail as it heats up.
