## Questions & Answers

**Q: will these work in my GE jvm3160rf2ss microwave?**
A: Worked in my Cuisinart Microwave. So happy I did have to by New microwave. I would check You tube videos About GE model.

**Q: How do you know which goes on top, middle and bottom?**
A: You need to check your microwave. Some switches are open and some closed so you need to make sure you put the correct type in the right locations, in other words putting a normally open switch in a place requiring a normally closed switch won’t work.

**Q: Do those switches work for ge jvm3160rf5ss?**
A: They worked for me with that model.  However, I also replaced the plastic holder unit.  I think the problem was not with the switches, but rather with excessive wear on the latch ramps on the holder.  Replacing it all worked.

**Q: Does it work with Kenmore model 790.80323310?**
A: yes

### ⭐⭐⭐⭐⭐ Fits perfect and works perfect
*by L***Y on January 25, 2024*

I replaced the three door switches in a Kenmore Microwave oven (Model NO. 721.69122010). It was the normally open bottom switch that went bad. It operates off the door latch and takes a beating when the door closes. Make sure you unplug the microwave first and then after removing the case cover discharge the big capacitor for the magnetron. Use a long screwdriver with an insulated handle. Short across the capacitor leads and to the case to make sure the capacitor has no charge before sticking your hands in the area of the door switches. The capacitor is in the same area and if its bleeder resistor is burned out or broken the capacitor won't bleed down. It will bite badly if you touch it and it still has a charge. Take a picture of each of the three door switches before removing so you can put the wires back on the terminals correctly. Replace one switch at a time. Be careful with the plastic retaining clips. They won't flex much and will break easily. There is a trick to removing and reinstalling each switch. There is a little plastic post that extends in the hole in one corner of each switch. Carefully lift the front retaining clip on the switch just enough to slide it out slightly swing it down and out and pull it off the post. It's important to not break the post. The removing and installation of each of the three switches is not identical but similar. It's tricky and delicate but can be done without breaking any clips or posts. Install them in reverse order. Do the switches one at a time. It took me about 45 minutes.
