Years ago my dryer stopped working out of the blue. The light would turn on and it made noises like it wanted to work, but it didn't move. I called a repair man who came out and gave the inside blade things a little push with his hand while holding the start button and it started right up. It's been working flawlessly ever since. It was like $90 just to have him come out, he even said he felt bad taking my money for that. Lesson learned.
