Hello from JA My name is Woody. I will be glad to assist you today. I have been servicing ALL Major Brands of Appliances for 33 Years, and have over 100,000 in home repairs and over 50,000 phone and internet repairs under my belt. YOU are saying the control is pulled !!
DO you mean when you push the start button ?
No the control button is used to set the type of drying (air fluff etc) and pulled to start the dryer.
Oh ok so you are talking about the timer- control knob. Now I see what you are talking about
If it somes times works and some time does not it will be internal of the timer .
Here is a link to the part .
