Perfect replacement for lfmv1846vfa
Fixed my microwaves no issues. I have a frigidaire lfmv1846vfa and it would light up but not make any noises when trying to cook. Simple replacement and works great now.

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.

worked great to fix my microwave turning off
Sasaqutch's microwave is a fridgedare but many have the two locking switches and this one i used for the monitor citrcuit - you can actually disconnect the monitor switch and the wicrowave will work. One of the 3 switches will be bad and not switching - there is a fuse in the upper right just above the input panel with a screw 3 inches down inside throught the top to release the control panel and get to the switches. My monitor switch cause the microwave to stop working - only after many times just opening the door on 1 second left then it starts to do it at any time. Sasquatch says, "good luck"

Fixed the problem cheaply
Cheap fix for a frustrating problem that caused the microwave to rotate when i opened the door. Lol Id be puttin stuff in It thinkin its cookin my arm lol. Ended up ordering these after watching a yt vid. I ended up not using these yet bc in the yt vid it said you could poss rehab the old switch and thats what we did and it wkd. These switches are identical and i have them as backups. Super cheap and now i have them in case it decides to go all maximum overdrive on me again. Highly recommend. 5 star
