HELP! Dryer will not shut off & timer won't advance

[SIZE=3]I have a Kenmore, gas, Dryer (Model# 110-77902792) purchased in July 1999.[/SIZE]
[SIZE=3]The dryer will not shut off (in all modes) until I open the door. Also, the timer will not advance (sometimes the timer will advance a centimeter, but will never advance to the end cycle to shut off the dryer.)[/SIZE]
[SIZE=3]I had an appliance service repairman come out and diagnosed the problem as a bad Control Timer. He wanted $185 to install it, which I couldn’t afford. So I purchased it on my own and installed it. This did not solve the problem, exact same symptoms. Since then I have replaced 3 additional parts and the SAME problem and symptoms exist.[/SIZE]
[SIZE=3]Here are a list of the parts I have replaced, in order:[/SIZE]
[SIZE=3]1) Control Timer (part#3976576)[/SIZE]
[SIZE=3]2) Thermostat (part#3387134)[/SIZE]
[SIZE=3]3) Thermal Fuse (part#3390719)[/SIZE]
[SIZE=3]4) Electronic Control (circut board) (part#3390537)[/SIZE]
[SIZE=3]I am at a loss as to what is wrong and completely at my wits end! Please help me. Our clothes are shrinking and my wife is pissed off. Thanks, Craig.[/SIZE]

Hi, Craig.

Does the dryer get hot?

If you manually turn the timer to end of cycle will it stop?

Thank you.
