Thanks everyone. After breaking the system down for trouble shooting I noticed a bit of sticky discharge around the solenoid and that doesn't seem right. I've got one on order and will start there. Thanks for the trouble shooting help!
Bet you a schooner of beer, you got it right!
I own a coin op laundry that had brand new gas dryers, following Katrina. Their use, as you might imagine, put a years duty on them in 2 months following the storm.
I begin to get many complaints that my dryers were "rigged" because they were costing more $. The worked fine by testing.
Guess what? The spring in the $10 solenoid valve had weaken and when warmed up, it started to "safety" shut off, cool a bit, and start again. Thus, they would not show fault and would take longer to dry clothes.
I changed them all and no more Dryer heating problems.
