Kenmore 110.73022101 Not stopping. Is this fixable or is it time for a new dryer?

Hi,

I have a Kenmore dryer model 110.73022101 that has many problems.
It turns on and heats up, but it will not stop.
In both "Auto Moisture Sensing" and "Timed Dry", the timer dial will not turn on it's own.
Even when the front loading door is opened, the dryer keeps running hot.
The only way to stop the dryer is to turn the timer dial to "Off".
Also the light inside the dryer seems to have burnt out.
Is this the end for this dryer? or can I somehow salvage it?

Thanks in advance for your time.
