Melissa H Casper , WY November 28, 2015 My timer and knob broke on my dryer We took the back panel off found our part number ordered our part from appliance part pros. I am very happy at the price and how quickly we received it in the mail. Popped out the wires from old timer switch and connected the new one and we were back to drying clothes in 20 mins.
