My amana dryer will not turn the tumbler. I took the top piece off and can hear a clicking noise coming from a small silver round container with two black wires next to the timer. The dryer does heat up. I took the front off and can see that the belts are still on. I've been having trouble for about a month. This didn't happen at once. Sometimes go for a week without any trouble. When it wouldn't start sometimes all I had to do was move the timer in and out or manually move the tumbler, then it would go. Any suggestions on what could be wrong. I hope it is something that is under the top piece with all the wires and small motors. Thank you for your time.
