Hi, I have a dryer that was left in the house we purchased that does not heat up at all on any cycles, will rotate the drum on timed and auto but not on the air dry cycle. The timer also does not move when on the timed cycle, it stays where ever you put it. We have flipped the breaker to make sure it was not half tripped, replaced the heating element and thermostats (before we realized the switch was not working correctly) with no heat still. Can the problem be in the timer switch? Any suggestions would be appreciated. Joanne M.
