The timer operates on "timed dry" just fine. On "Auto Dry", the "timer" does not advance at all. The dryer heats up just fine, and drys the clothes, it just never shuts off in the "Auto Dry" mode. I have changed the sensors and the cycling thermostat, but that had no effect. Checked all wire connections at timer, and door switch works fine. Dryer does not seem to get overly hot, and I do hear the burner kicking on and off, periodically, during the "timed dry" use of the dryer. Checked all vents, vent connections, blower, and blower housings. They were spotless and working fine.
ANSWER Hello Fred,
If the unit will advance on the timed dry setting but not on the automatic settings, the problem isn't with the dryer, but with the exhaust duct. I've had arguments about this before so to avoid this, let's try an experiment. If the problem is the duct, the dryer will advance on the automatic cycles if the duct is disconnected. So disconnect the duct and watch the timer on the automatic setting. It may take 5 or 10 minutes for you to notice that it has advanced, but it will.
Let me explain why this is. On the timed cycles, the timer motor has voltage applied to it at all times, so it advances at a constant rate. On the automatic cycles, the timer motor only gets voltage when the moisture sensors inside the unit are not picking up the presence of moisture. If the unit advances when the duct is off it's because the moisture has been purged from the unit and voltage is now being supplied to the timer.
