Review: RYOBI grinder… FIXED! - Used in a Ryobi angle grinder to replace the trigger switch. Works like a charm now. Have an extra, should it not last too long. But seem to be working fine.
Review: SZM-V16-FD-93D (Replacement) GE Microwave - My GE Microwave Model: PEB7226SF1SS would turn on when the door was open. I figured that the issue was a door switch. I could not find the exact part number needed, SZM-V16-FD-93D, for my GE Microwave. I trusted the product description that it was compatible with the part I needed. You will need a T20 Security Bit, which I purchased a set of 100 bits at Harbor Freight for $10, to open the microwave. Before unscrewing any screws and disconnecting wires, I took pictures of the components for reference when I needed to put things back together. The hardest part of the installation was removing the wires from the old switch. I needed to use pliers to remove the wires from the old switch. Installation was fairly quick and easy. Purchasing this LONYE 3405-001034 Microwave Door Switch(SZM-V16-FD-63) Normally Open, my microwave is now working as normal.

## Questions & Answers

**Q: will this switch fit a kitchenaid kmhs120ess ?**
A: hello,this switch does not fit your model. W10727360 & W10269458 & W10269460 switch fits for your model.You can check the ASIN B07PF3CYDC to know more information.

**Q: I installed this switch and the microwave powers on but now it trips the breaker. Do I have a faulty switch sensor?**
A: Sounds like you have a different issue to troubleshoot.  Google your model trips circuit breaker and run down the list of possible reasons.

**Q: does this fit a37022c  fa63**
A: No idea! I am just a consumer that had a microwave that needed a switch. I can ordered two, got them, installed them and it fixed my problem,

**Q: Will this work on GE jnm3151df1bb?**
A: In general, a microswitch like this will work if it is physically the same as the original and of the correct type. The two types are NC, normally closed, and NO, normally open. There will usually be a symbol on the switch to denote the type. A normally closed switch will have a symbol that looks like: horizontal line, dot horizontal line, dot horizontal line, all continuous. Think of it as as an overhead view of a door that is closed.  A normally open switch will have the symbol horizontal line, dot, line at 45 degrees up, not connected to second dot, horizontal line. Like a door open. You can look these symbols up. After making sure that the circuit is discharged (LOOK  IT UP OR IT MAY KILL YOU), remove the old switch carefully. Disconnect the two wires and connect them to the new switch as they were originally connected. Reinstall everything. You may have to fiddle with the frame that these switches fit into to get the door to work right. Good luck.

### ⭐⭐⭐⭐⭐ Well worth
*by A***H on December 15, 2024*

My GE microwave started to make running nose even wasn't on use. And found out from U-tube. I need to change this. I did have to drill a hole to reach a screw to open to get this part area so I can replace. But after exchanging no problem to microwave. I didn't need to spend money on new microwave and installation of over the top stove installation. I probably saved over easy $400. Thanks for selling this part. Also thanking all the U-tube videos of how to reach and replace this part.
