Review: Saved me hundreds! - If you have a little know how these will save you plenty of money by repairing your microwave yourself. I replaced the failed switches in my GE unit this past year with these and they're still going strong. They fit perfectly and were easy enough to install into my unit. I've had no issues since installing them and they've been in my unit more than a year now. I'd say they're pretty durable for sure. Do yourself a favor buy these switches and repair your microwave yourself. Just note it's not super clear two switches are normally open and one is closed- use your multimeter to ensure you're installing these in the right locations.
Review: Good replacement switches - The switches work. I replaced all 3 for my door. Our microwave was randomly blowing its fuse. It’s started if we accidentally opened the door while it was running. Then it would blow randomly. Might work for a month then might pop 2 fuses in a week. So time will tell if one of the switches I replaced was the actual issue. Just pay attention so you know which switch goes where when installing.

### ⭐⭐⭐⭐⭐ Fixed the micro switch for the microwave door.
*by T***M on October 8, 2025*

Fixed the lower latch micro switch for the door. Microwave is working perfectly again. Only used one switch. The wires were all keyed to changinging it out was pretty simple. Used my meter to make sure that I had it right. The price could not be beat! A replacement over-the-stove microwave would have been over $350 for a model similar to mine.
