Stays on in more dry/less dry setting

Hello, anyone have any thoughts? The timer knob appears to advance when it’s in the ‘timed dry’ mode but when it’s in the automatic more dry/less dry mode the dryer seems to run and never turn off even though the clothes are dry. How does the more dry/less dry mode work? Is there a sensor of some type that tells the timer to run or turn off? If there is a sensor is it inside the timer or is it located some other place in the dryer? Any help would be very much appreciated.

Thank you

[SIZE=3]This dryer has two heating elements and if one goes out the timer will not turn in an automatic cycle. But because there is another element working you will feel heat inside the dryer and it will eventually dry the clothes. For more on this visit GE Dryer Timer Won’t Advance[/SIZE]
