## Description

desertcart.com: LONYE KW3A Microwave Oven Door Switch Fit for Microwave DR52 16A 125/250V(Normally Open & Normally Close) : Home & Kitchen

Review: Install switches in correct position (upper or lower), they are not identical. - I have a six years old microwave, courtesy of the original owners of my home, and the door latches just stopped working properly (door stayed shut). When I searched online I found a review of my model microwave where the reviewer had door problems and fixed them by replacing the door latch switches with these. I ordered the 2Pack of LONYE KW3A Microwave Door Switches (1 normally closed & 1 normally open) suggested by the reviewer. As my unit is built into the kitchen cabinets with an expensive trim set surrounding it I wanted to be sure that the suggested fix would work. Well it worked beautifully, THANK YOU Tyler Bradley! Although it seemed like only the upper switch wasn't working I decided to replace both while I had the microwave on the counter and opened up. If one switch goes bad how long before the second one follows suit. The microwave is working fine now. Although I would not have bought this microwave myself it does the job for us.
Review: Wow - I can't believe I was about to take my microwave out and replace it with another for almost $400. A quick YouTube video and this part here in about half hour time the microwave is working perfectly. Very simple to do just make sure that you unplug your microwave before you work on it.

## Questions & Answers

**Q: Is this kw3a interchangable with kw3at-16? i have a frigidaire electrolux model. all specs seem identical except this 1 detail**
A: The 16 refers to the amperage, so if you look, this is good for 16 amps.  I'm not sure exactly which of these switches you need, the Normally Open or the Normally Closed, but there is one of each in this set.  If you look at the diagram on the back of your switch, you will notice that where the connection comes out of the side, that it will indicate if it is NO or NC switch.  I'd replace all of the switches in your microwave that you have. Mark them before you take them out so you know which replacement switch (NO or NC) goes where.

**Q: Does it work for emerson mw9339sb**
A: I only use the switch for another purpose in different types of equipment very useful

**Q: Will this fit model #jvm1440bh04?**
A: hello,this part fits for your model.

**Q: will this fir kenmore microwave model 405.72122310?**
A: It should, I used it to replace the switch in my Kenmore microwave model 405.72129310 (color black).
My microwave User Guide listed model 405.72122310 is white, same microwave different color.

### ⭐⭐⭐⭐⭐ The right parts at a fair price.
*by R***. on July 17, 2020*

This was a lifesaver for us. The Kenmore 790.80333310 microwave quit the same day we started having refrigerator issues so we had a local repair man on the way. He said that all Microwaves are losers to invest in fixing as he said the chance there could be repeat issues is too high to justify a $200 plus repair bill. Being handy I looked online and found the parts needed and Amazon was cheapest. I also bought these fuses. BlueCatELE. Microwave Fuse Ceramic Fuse Cartridge Fuse 20 Amp 250V Slow-Blow Compatible and Universal Replace for GE WB27X10388 and Whirlpool Kenmore Other Microwave 5 PCS The replacement of the two switches was easy and it worked saved a $300 plus microwave and the cost of install on a new one which is about $160 plus. Fair warning multiple repair sites say fuses could blow again. So decide if you want to invest the time about 35 minutes between ordering and your labor it might save you buying new.
