I’m not sure where to start, I want to do this one without calling the repairman. Our dryer was purchased only 2 years ago and now no longer stops drying on it’s own. I’m not sure what item(s) to purchase first the timer or something else.
Not willing to give the Husband or the Father the satisfaction either! 
Addeded Info: Dryer heat like normal and just keeps going until you open the dryer door.
