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

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 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.

My Toshiba microwave would start running when I opened the door. It also wouldn't shut off if I opened the door during heating. It ended up being a bad switch, just the one at the top. Fairly easy to tell with the cover off, giving them a tap and not hearing a solid "click".On my Toshiba, the colors are reversed. Normally open is red and normally closed is black. Just swap the bad switch with the same "COM+NO/NC" replacement as printed on the switches and ignore the color. Take care when getting the switch out as the plastic container clips can snap easy.I replaced my stuck (red) LF-10-02 switch with a (black) switch from this purchase and now all is well. Far cheaper than buying a new microwave and it took less time to fix than writing this review... but I figured this might help some others.

I ordered the (2 Normally Open and 1 Normally Close) Brand: Yoiilnz three pack and replaced all three switches in my friend's microwave oven. His oven only needed the normally closed switch (The Monitor Switch) in their Frigidaire by Electrolux microwave model FFMV164LSA. These new switches installed without issue, and everything now works as designed. The switches were delivered in two days and appear identical to the original other than color of the plastic. The problem he was having was that as soon as he hit the start button to heat something up it would trip the house circuit breaker. While doing research on the issue the most common cause reported was a broken (Stuck in On position) middle (Monitor switch). That is exactly what I found on his unit. With the monitoring switch in an always on state it causes a direct short which then trips the circuit breaker. I can recommend these aftermarket switches instead of spending 10 times as much for OEM.

Great value, works good

These switches saved my 2018 microwave. One of the original switch got burned after 7 years of use. My microwave fan and plate ran even when the door was opened. It worked like that for a few months then it stopped warming food probably due to a fail safe mechanism. I replaced with these switches and my microwave works like new now.

These worked perfect for our microwave. Replaces all 3 since it was apart already and it works like new. Good product so far. Build quality mirrors the OEM parts and feels like they will stand the trat of time. Price was right and they arrived quickly.

After watching a YouTube video about what to do this saved us repair money and the possible cost of a new microwave. Huge money saver!
