He came promptly and fixed dryer than would not shut off. Within a week or two the dryer would no longer turn off. He came back. I think he changed a part. Within a few weeks the dryer would not shut off again. I just gave up after that. That was several years ago and every time to manually forget to shut it off I get annoyed that I paid for something to be fixed and it wasn't. It will run for days if I don't turn it off! Nice guy though.
