Keith H Coral Springs , FL May 06, 2016 Appliance: Amana Gas Dryer LG1009W Amana Dryer Lg1009w / P1177602w W: Microwave would count down like it was on but not working. How to replace Microwave Door Switch. Chatted with appliance pros and they determined it was one of the door switches. I ordered both and when they arrived I watched a youtube video on similar problems. So I took control panel off and found switches and replaced top one first. Took 5 minutes. Low and behold my microwave turned and and was working. Thank you appliancerepairpros.com!! You saved me $145 on a technician! ! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
