Duane H New Milford , CT February 18, 2020 Appliance: Model WMH31017AS-5 Light flickering when you open the door Replaced the 3 micro switches and the switch interlocks. I would recommend when changing these out to purchase the new interlock holders. The microswitches snap in place but when try to remove the side clips snap. For the extra 20.00 for both interlock holders well worth it. I had to order after the fact but received the next day. Within 30 minutes I was done and microwave works perfectly. Thanks for the great prompt service. 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
