I recently replaced a thermastat on this unit. The wires were even burnt leading to the thermastat that I repaired.
The dryer worked great for a few weeks. It still dries the clothes fine, it does NOT take any longer than it used too. However, it will not shut off! We must shut it off manually The timer will roll past and in fact goes 360 degrees. It does stop once the dryer is manually shut down.
So it appears to me that heat is produced fine
The dryer starts fine.
The clock motor in the timer must be fine to advance the timer.
So does this mean that there is a malfunction in timer itself?

Thanks in advance for your help.

No Not Defective Timer There Is A Thermal Cutoff Switch Above The Thermostat In The Ductwork Thats The Problem

No that's not the fuction of the thermal, a thermal is a protective fuse that can blow to stop the current and protect a motor or element!!
When a dryer won't stop, it's usually a start button burnt out and stuck in the on position, so the motor can't stop. Or sometimes the contacts in the timer weld themselves together and it keeps the motor from stopping.

I Understand That You Are Correct But There Is Also A Thermal Switch In The Ductwork To Advance Timer

The Timer Gets It's Power Right Off The Power Cord!!!!!!!!!
The Thermals Protect The Motor And The Heater, And Get Their Power From The Timer!!!

Then.... if the start button was shorted the motor would run all the time. Which it don't. I can stop the dryer by only opening the dryer door. I doubt it is then the start switch because the it does not start the dryer until pressed.
I will pull the timer to see what the contacts look like. If it checks, then what do I look at. The thermal switch in the duct work checks out as a short using a Fluke.

Took the timer apart and found the contacts flashed and burnt. In fact, the outside of the timer itself has been hot and burnt.

I have to answer your question you asked about "I can open the door and stop the dryer" think about it, opening the door, stops the current, just as if you unplugged it, but I'm glad you solved your problem, Bettyboop!!

Betty,
I would hope the door would open the current path. It was suggested elsewhere in this thread that the start switch was shorted all the time. That lead me to believe that if this was the case, motor would run all the time???

I have a similar problem the dryer shuts off but the timer continues to run even after the buzzer and removing the clothes. Any ideas It's an older maytag but works great besides this timer problem.
