Charles S Wake Forest , NC January 03, 2020 Appliance: Maytag Microwave Hood Combo MMV5208WB1 Maytag Microwave Mmv5208wb1: Blowing fuses and breakers. How to replace Microwave Door Interlock Switch. I replaced all three door switches and installed new fuse. Took about 30 min. It worked great afterward. One of the door switches was burned up and fried. It was shorting and blowing the fuses. I went ahead and replaced all three in hopes that this won't happen again for a long time. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
