I have a 110 volt Kenmore 110.88670100 dryer that recently started working badly. When I would push the button after turning the timer there would be a loud sound of an electrical current but the tumbler would not engage. If the button was pushed heavily eventually no electrical sound. After awhile the button would go back to loud electrical sound and the tumbler not engaging. When taking the top off the sound seems to generate from the circuit board and timer assembly. I have replaced the plug in, the band that goes around the tumbler, and the push to start switch. Whenever I had the top off I would push in the start switch and see a light flash in its assembly. When pushing in the start knob I push the button a little to the right and it does turn on. I have ordered a new push to start switch and a board and timer assembly. Does anyone have any ideas? Any help would be greatly appreciated.
