Bruce K Severna Park , MD September 24, 2014 Appliance: Model 110.86984100 Kenmore dryer would not run Replaced the Timer. The old timer (not me!) had a contact pad fall off on the W contact, which caused the problem - but I had to destroy the old timer to know that. To diagnose the problem, I took voltage readings on all the contacts of the timer in the"on" position. The W contact never had a voltage, so the motor never turned on. With this diagnosis, I was pretty sure that the timer was bad and proceeded to take it apart to confirm it. Dryer is working fine - 28 years old and works great. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
