hopefully someone can diagnose this problem. My Kenmore electric dryer
won't start sometimes.

Last week when my wife tried to start it, the dryer hummed but would
not start. After trying a few times to start it, it looks like
something trips and the hum goes away when you pressed the start button
and it still would not start. ....

How old is your house? We had a similar problem. The dryer was under
warranty and the repair guy could not find the problem. I pulled new
wiring from the breaker box and have not had another problem.
