KW3A Microwave Oven Door Switch 16A 125/250V Door Interloc (2 Normally Open and 1 Normally Closes)

These replacement micro switches fit my air fryer perfectly and work like new. Easy to install and very reliable. Restores full functionality to the appliance. Great quality for the price.

Good product and fast delivery. Fixed the issue (table turning while door open). But check which one is normally open or closed by checking the pins. Don't go by color. In my Oster microwave normally open switches had red button and normally closed are black button. The replacement switches have opposite color code.

It worked for my situation. I had one burnt. I could visibly see it and it no longer clicked. This replacement fixed it . I still have the other 2. I wasn't sure which one was bad at first so I purchased all 3.

I wasn't sure which switches to order, so I took a chance on these, and they worked perfectly. Saved me a bunch of money!

I bought this set for a Samsung SMH1816S microwave oven. It has the exact set of 3 switches I needed - 2 normally open and 1 normally closed. I've previously replaced similar switches on the same oven with a different seller/brand and it was fine. This time, I came across a problem I had not seen before; nor have I seen this problem on other similar switches used in other situations. The problem is that the male contact lugs for these switches are thicker than the corresponding female lugs in the Samsung wire harness. For one switch, it took a little extra force to push the wire harness onto the lug. But for the others, it didn't work and I wasn't willing to force the harness any harder for fear of damaging/breaking the plastic parts holding the switch in place. Comparing the new and old switches, the difference in thickness is visible to the naked eye. Judging by other reviews, this problem isn't universal but it sure is a problem on my Samsung unit. Since only 1 of the 2 N.O. switches was broken, I was able to move a good one switch to replace the bad one and install a new one in the spot that took a little more persuasion. So overall, good value and well made, but not good on the installation. Buyer beware.

Excellent! Fixed my Samsung microwave for a whole $8! My microwave strangely started turn on when I opened the door - potentially cooking my face! It was inconsistent too - sometimes working as expected and sometimes becoming a dangerous radiation hazard. I searched online and it’s a common problem that was also an easy fix. Simply remove your microwave front cover and find the numerous door sensors. If you can squeeze a finger or thin stick in, feel the click of the sensor. If it’s a sharp satisfying click then it’s good. If it has a weak or no click then it’s broken and it causes the microwave to be confused about when it’s open and when it’s not. Fixing it really took like 10 min. Just follow numerous guides on YouTube. The most confusing part was trying to figure out if it’s an open switch or closed switch. If you look at the diagrams, the metal pins are in different locations. I bought one of each just to make sure. It was $8 in total so I’m not compliant about buying and extra.

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.
