A year ago I replaced the timer motor assembly. Not when my wifes uses the delicate or cotton cycle which is all she uses it won't turn off automatically.
I ran the TIMED, TIMER mode and it worked.

It looks as if the dial is NOT advancing on the other modes?

Thanks for any help.

I will look in console today, there was a paper in there, I put it back for future references.
I will look for a sensor.
Replace or Clean? I'll probably be able to tell.
THANKS !!!!!!!!:D

Various machines have different methods of doing automatic drying cycles based on the wetness or dryness of the clothes.

Some models have sensor bars, which when made wet by the clothes will "short out" the timer so it does not turn. As the clothes dry, the sensor will stop shorting out the timer so it runs and eventually turns off the dryer.

If you do not have sensor bars then you may have a system where the timer does not run when the heater is on. Since the heater is on more when the clothes are cold and wet, the timer runs very little in the early part of the process, and a lot at the end.

This may be what you have.
