And have some painters blue tape so you can mark each plug that is unpluged. with the ge unit there were three switches, but the cord of each can be plug into any of the plugs, so i had to mark the top on 'top', the middle 'middle' and the bottom 'bottom. yes as take plenty of pictures as you progress. it took me about two hours--but i am not very handy. good luck **Q: Will this fit toshiba ML-EM45P?** A: Product model and compatibility: the model number of microwave door switch is KW3AT-16, and it can be compatible with SZM-V16-FD-63 SZM-V16-FA-63 3B73362F PS3522738.

After replacing one switch, the microwave immediately works again. So happy!The price is very good too. ### ⭐⭐⭐⭐⭐ Did not have to replace my microwave!!! *by M***V on April 8, 2025* I thought I was going to have to replace my microwave when it stopped working. I checked out YouTube U and found several willing souls who showed what might be wrong and how to fix it. My fuse was bad, so replace it and it worked about two times and killed the fuse. But the video stated if this happened then you needed to replace the door switches (you need to make sure you get both the 'normally open' & 'normally shut'). Was not difficult to do on my over-the-stove microwave. So happy I did not have to replace it!!! ### ⭐⭐⭐⭐⭐ Love this connector *by I***R on April 21, 2023* Love this device easy to individual and save me money on buying another air fryer. ## Frequently Bought Together - 4 Pieces Microwave Oven Door Switches KW3AT-16 Switches Replacement Parts Compatible with SZM-V16-FD-63 SZM-V16-FA-63 3B73362F PS3522738 16 A and 125/250v, Normally Open - BOJACK Microwave Oven Door Switch KW3A 16A 125/250 V Door Interloc (Pack of 2 pcs Normally Close Switchs) - BOJACK Microwave Fuse 20a Ceramic Fuse 20 Amp 250V Slow-Blow Compatible and Universal Replacement for WB27X10388 and Other Microwaves --- ## 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.sn/products/266527561-weewooday-4-pieces-microwave-oven-door-switches-kw3at-16-switches](https://www.desertcart.sn/products/266527561-weewooday-4-pieces-microwave-oven-door-switches-kw3at-16-switches) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-03*
