Peter C New Britain , CT April 23, 2023 Appliance: Model KENMORE MODEL #721.66462500 Would not turn on when the start button was pushed. AppliancePartsPros.com provided possible causes and possible fixes. Took the recommendation of replacing the door micro switches and delay fuse. I replaced the 3 items and voila it works. Did not even check the old switches with a meter, I just replaced them. The cost was worth it as I was prepared to go further to repair it anyway. And don't forget to discharge the capacitor. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
