Review: piece de qualité - interrupteur de tres bonne qualité
Review: Buen repuesto. - Buen repuesto. Fácil de instalar y funciona de maravilla. Nota.

## 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.
