We realized on Saturday of this weekend that the dryer never stopped running. Even though the lint filter was clean and the ductwork was clean too. It looks like it is the timer. No matter where we set the timer (auto, timed, etc.), it never moved while the dryer was running. This isn’t going to be a $2.67 repair (like the dishwasher). A new timer is a little more than that. While I had some of the dryer apart I decided to vacuum out the cabinet inside. While rotating the drum by hand, I saw some noticeable wear on the drive belt. Oh well, another part.
New timer and drive belt have been ordered from www.appliancepartspros.com.
