Replaced timer and control knob. Glad I ordered the control knob, because that had cracked and would not advance the new timer (push to start switch was still good, so didn't really need it). Took almost as long to remove the back cover panel as to swap out the timer. The screws were very tight, had to go slow and easy to not strip the heads. No screws securing the timer, just a wing clip, easy to release and rotate the unit out. Swapped out wire connectors one at a time. Easy fix. Thank you AppliancePartsPros for making it easy to get the parts needed.
