Review: piece de qualité - interrupteur de tres bonne qualité
Review: Buen repuesto. - Buen repuesto. Fácil de instalar y funciona de maravilla. Nota. No sabía que al empezar a fallar este integrado el plato del horno gira cuando abres la puerta, y el siguiente paso, es que deja de funcionar el microondas; sin embargo, cuando sustituyes esta pieza, todo vuelve a la normalidad. Reitero, es un buen repuesto. El único pero es que tardó un poco en llegar, pero si lo pides cuando empieza tu horno a fallar, va a llegar justo a tiempo para sustituirlo.

## Questions & Answers

**Q: Will this work for magic chef microwave model hmm1110w/hmm110b?**
A: You need to pull out the defective switch and read what’s on the switch is it rated for 115 VAC 16 amp normally closed.. Most microwave doors have three switches some open, some closed. If you already know which one is defective then the label on it will tell you what you need. My microwave was a GE and this switch worked perfectly.

**Q: Does this fit Panasonic NNSC668S door?
Even after opening the door, the microwave keeps running.**
A: When my switch broke and while waiting for the replacement switch to arrive, I jumpers the two wires so I could still use the oven.  Oven worked but would not shut off when the door was opened, which really surprised me.  Once the new switch was installed, oven functioned correctly.  Make sure the switch lever is able to fully cycle the switch.  It sounds like your switch is acting as if the wires are jumpered.

**Q: Can this item replace the cuisine art oven toaster toa-60 model?**
A: The only way to make sure is to disassemble Otto the point you can read the part number that’s broken

**Q: Is this compatible with the V-5230Q switch used in Wolf microwaves?**
A: I dont know.  If it's on the list of compatible microwave it will. I think you can address this question to the manufacturer and cross reference.

### ⭐⭐⭐⭐⭐ replacements including part number look identical to OEM
*by P***B on 14 September 2025*

Looks identical to original number code and manufacturer. So inexpensive I replaced the top and upper bottom switch even though only one was bad. Replaced very bottom switch, an older style with same code as original. Works fine in my convection/microwave Figidaire Pro.
