Found out it was this door switch. Check videos online on how to replace it. Key Fob Rob has the best one. I suggest disassembling and testing all three switches before you order anything. You might need only one. Based on others comments it seems to be the middle switch (normally closed) that usually has the problem and that rang true in my case. If your microwave has no power (lights, clock, etc.) and it's not a tripped breaker check the fuse and order that while you're at it. Both are easy to fix and saved me from buying a new microwave.EDIT: Check your latch board also. After replacing the switch the breaker tripped again when I pulled open the door mid cook cycle (which I learned is hard on the microwave, press stop/cancel instead). Sure enough the switch was fused together again. Come to find out the switch going bad is just a symptom of the actual problem which in my case was the latch board having a groove worn in the spot where the latch hooks on. The safety system of the microwave relies on those switches being tripped at exactly the same time when the door is opened. If not then one of those switches sacrifices itself which causes the breaker to trip. Examine the edge of the holes where the door latch goes. They should be perfectly flat (see pic new vs old). Although it's hard on the microwave to open it mid cycle, I found that is the best way to verify everything is working as it should after you're finished with your repair. ### ⭐⭐⭐⭐⭐ This fixed my microwave *by on Reviewed in the United States October 6, 2021* My microwave threw the breaker once I started cooking something. I replaced one of the door latches (after figuring out how to get to the latches and test them for continuity) and now it works. It still throws the breaker whenever I open the door to interrupt cooking, so there is some other issues I have not solved. But at least I can use the microwave again as long as I remember to cancel the cooking before opening the door or else wait for it to complete the cook time. ### ⭐⭐⭐⭐⭐ Quick and easy fix for GE Microwave *by on Reviewed in the United States May 30, 2024* Works for the GE Model JVM3160DF3WW microwave. I tested the switch with a multi-meter before I installed it to make sure it wasn't a dud, it was a good. Easy install and worked liked a charm. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/248479943-hiqltyla-microwave-door-switch-replacement-kw3at-16-16a-125vac-1nc](https://www.desertcart.us/products/248479943-hiqltyla-microwave-door-switch-replacement-kw3at-16-16a-125vac-1nc) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-23*
