I'm having a problem with an Estate gas dryer, model # TGDS740PQ.
One of the symptoms is that the Timer knob moves when in Timed Drying mode, but not when in AutoSense mode. The other symptom is that it takes a long time to dry a load in any mode. Even when the clothes are completely dry, the AutoSense knob, which should move towards Off once the clothes are dry, never moves. The dryer would run forever if I let it.
I should point out that the clothes are not always warm when I check them, whether they are wet or dry. Sometimes they are dry and toasty warm, sometimes they are dry and cool, sometimes they are wet and warm, sometimes wet and cool. My understanding of the way the cycling thermostat works, they should *never* be wet and cool. But even if the cycling thermostat was bad, why would that cause the knob to not move in AutoSense mode?
I looked at all the parts for my dryer at the following site and can't find anything that looks like a moisture sensor. How does a dryer sense the moisture and decide when it's done?
