My gas dryer is not shutting off on auto, but stops on timed dry. The sensor bars seem fine and have continuity when shorted at connector on control board. Any other things to look for?

Answer Hello Dan,
The problem is your duct. It is either crimped, clogged, or too long and complicated. Think about it like this: The dryer has moisture sensors inside it. If the exhaust cannot allow the moisture to escape, it will blow past the felt seals into the cabinet, which is actually the air intake, (note the louvers on the back of the unit), where it is recirculated back across the clothes and sensed again. I have argued with customers for years over this exact issue and the only way I can prove it is to dis-connect the exhaust duct. After about two minutes it is obvious that the timer has advanced. Check the exhaust and I'm confident you will locate the problem.
