The timer on my dryer quit working. The dryer still ran, but the timer would not run down.

This was one of the easiest repair jobs I have ever done. The top panel on the dryer has a removable back so that you can get to the controls. I simply removed the screws on the back panel, and the timer was right there. The timer is held in place to the front panel by one screw, and there are 3 wires that plug into it. Those wires have a head on them which slides easily into place on the new timer. It is really easy to see which one goes where. So all you have to do is remove the screw and the 3 wires, put the new timer in place, attach the wires to it and screw it back in. Also, you need to remove the knob from the old timer (it simply pulls straight out) and replace it on the new timer before you screw the timer back in. I made the mistake of thinking that the knob attaches to the timer from the front, after the timer is in place, but the knob will not stay in place that way. The rim of the knob is actually behind the front panel, so that it doesn't pull back out. Super easy job!!! Good luck!
