I have a Kenmore, gas, Dryer (Model# 110-77902792) purchased in July 1999.
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.)
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.
Here are a list of the parts I have replaced, in order:
1) Control Timer (part#3976576)
2) Thermostat (part#3387134)
3) Thermal Fuse (part#3390719)
4) Electronic Control (circut board) (part#3390537)
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.
