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?

BTW, before anyone mentions it - I tore the dryer apart this weekend
and cleaned it from the opening in the back of the drum all the way
out to the vent. This didn't help, but there wasn't enough lint to
have caused a problem in any case.
