### ⭐⭐⭐⭐⭐ Good

Worked well

### ⭐⭐⭐⭐⭐ To help someone else
*by B***N on June 6, 2023*

The short version.Label the old switches with a Sharpie, 1, 2 and 3. Also mark the locations inside the microwave 1, 2 and 3.Match the side prong of the old switches to the side prong of the new switches in each location and replace. See picture. No multi-meter required if you don't know what it is.Just take your time and don't break the plastic prongs that guide the placements of each switch. Don't touch the capacitor (looks like a giant battery with 2 terminals), has a charge even when unplugged.The long version.When doors open (the natural state of the switch in my microwave).The top is NO, the middle is NC, the bottom is NO.When the door is closed, all 3 states reversed (the switches' buttons are depressed by levers).The top is NC, the middle is NO, the bottom is NC. Just in case you did not heed my advice in labelling, or you are reading this after the fact.NO = Normally Open, NC = Normally Closedin my case, the top switch was stuck (the black push down button on top left), I thought they rigged it to be always closed (wrong), I open it up after I replaced it and it sprang back up. If the button is always depressed, then that's the stuck switch. Check the others for continuity, you should hear a clicking sound.Set the multi-meter to Tone and put the prongs in each leg.NC beeps w/o pressing the switch.NO beeps only when you depress the switch.Before you take each switch out, perhaps you can test the switches in place, it will save you time.If you don't have a multi-meter, then just replace all 3.in a pinch and you don't have replacements, you can try cleaning and sanding it between the contacts. Use a razor blade or small screwdriver to ply it open. If you already have the replacement. You can change only that one, but since you took it apart, might as well change all three. The contacts on mine were coated black—it's more than 10 years old. But you can probably still clean it and reuse. I didn't bother.Disclaimer: If you don't feel comfortable doing it yourself, ask someone to help. Unplug the microwave, and don't touch the capacitor, it's charged even when unplugged. it's the thing that looks like a battery, with two terminals next to one another. In mine, it was on the far-right side. Take your time, don't break any of the plastic prongs/holders that secures the switches. Good luck.

### ⭐⭐⭐⭐ NC (Normally Closed) stamped on all switch cases but half were NO (Normally Open) switches
*by A***R on June 18, 2025*

All of the switches have the NC symbol on the case (Normally Closed). After testing all of them with the meter found out that half of them were Normally Open switches. The average person without a meter would have sent all of them back assuming that there were no Normally Open switches in the box.
