KCMS2055SSS - Instructions

The reason the door would not open upon pressing the door opener is because the BRCKT-LATCH was broken. I discovered that after opening the microwave enclosing. The BRCKT-LATCH has two ends sticking out....each fits into a hole. One of the ends on the LATCH was broken and therefore it was not tightly fit. No upon pushing the door opener the LATCH would not function properly since it was loosely fit and hence the door would not open.
To Fix this issue:
1) Buy a new BRCKT-LATCH
2) Remove the microwave enclosing. I had to use a special screwdriver, since the screws were security protected on my microwave. After removing the case, I opened the door by manually pressing the door latch upwards (please make sure that the microwave is not connected to the electric socket before removing the enclosing).
3) pull out the old LATCH from the microwave.
4) carefully insert the new LATCH. Try not to put too much pressure when trying to fit the latch, or else the ends may snap again!!
5) Close the door and try opening it by pressing the door opener. it should work now!!

Remove top grille (2 screws), undo control panel (1 screw). Tilt down control panel, switches are on the left. There are actually three switches that are involved with the door, two horizontally mounted, one vertically mounted. This would be an EASY REPAIR, but it took me a while to figure out which of the three switches was bad, and also took a while to figure out that there is a plastic rod that inserts through the hole in the switch body. Once i figured this out went like a breeze. Lower horizontal switch was the bad one, but since the kit came with two switches i went ahead and replaced the upper horizontal one as well. IT appears that the horizontal switches are probably more likely to fail than the vertical switch based on the position of the switch and force angles. Works great now!

After watching a few youtube videos, I used a phillips SD to take controll pannel off to access the switches that sense when microwave door is closed. Swapped out all 3 switched and mocrowave works like new. $20 fix (shipping included)

The repair went well...I am so glad that I read this info before buying a new microwave....it saved me lots of money. I did have a repair man come and look at it and he told me to buy a new one but it cost alot of money when it wasn't necessary. I did the repair and I was very proud of myself.
Three men watched a woman fix this and it was no problem...they were impressed also....

My 8 year old daughter cleaned the inside of the microwave with enough water to rival a tsunami. Resulted in a clean microwave with a fried out motor that no longer revolved. Part came quickly. Took cover and bottom off to get to the part. One screw held it on and a plug. Removed those, put on new part and she was good to go. No trip to home depot today.

I looked up the #1 reason for no heat for my microwave on the site , and using my model number found that 92% of the time it was the Black Sleeve Diode. Ordered the $15 part, and installed it within 30 minutes. Most of the time was used for removing the built in microwave and removing the cover. Replaced the diode by finding it on the diagram that I printed from this site (free). Very relieved that we don't need to have our custom cabinetry re-sized to accommodate a new microwave. Thank you!

I used a phillips head screw driver to remove the screws from the sides of the cover. Then used a special torx "security star" screw driver (size t20) to remove the star-shaped screws along the back edges of the cover. I removed the cover from the microwave and set aside. I used a butter knife to gently pry the door latch bracket from the peg holes and removed the broken part. I then used the butter knife to help GENTLY insert the new latch into the slot. I replaced the cover (making sure the front and sides were tucked into the grooves of the frame and then replaced the screws and tightened. All in all, a very easy and inexpensive fix.

After determined the problem on one of the websites...I received the part I needed... removed the control panel and installed the new main fuse In about 15 mins!

The hardest part was taking it down from the range hood stand. Without being able to open the door, the glass carousel was moving around. We removed about 7 screws. Luckily we had the special type of allen wrenches (ones with a hole in the middle). It was easy to see what had broke and that it would not be fixable. We tied fishing line to the door hooks so that we could use the oven until the part came in. When I seached the internet and logged onto your site, keyed in the model # and the item I needed was the first item with a picture. I was absolutely sure it was the right part. The price seemed high, but I checked with our local applicance where I bought the oven and it would be the same cost from them and they have always be reasonable. Ordered the part, arrived within 2-3 days and it took only 30 minutes to install. You need to press down on the side of the part (spring loaded) to pop it in place. Helpful to turn the oven on its side to get leverage. Just go slow as the part is plastic. I will use your site again. Thanks.

I removed the unit from the wall. Took the cover off. Set the unit on its side. It revealed the working parts. Removed the old micro switches. Put in the new oness. Presto, it worked. Very easy for me.
The parts was delivered almost before my notice they were shipped.

Fun and easy fix for my kids.

The countdown timer was working but no "cooking" happening. Did not hear the familiar sound of the heating part working.

Determined it might be some simple switches for under $15 dollars. Bought one of each. They allow the microwave to turn on/activate by signaling that the door is properly latched. My wife noticed that it was failing and then failed over the course of about a day. Several times where it worked, then did not work. The timer was counting down one time and then when she opened the door the microwave heating component turned on. Guess it had activated the switch as she was opening the door.

Procedure to repair
- Unplug
- Remove two screws on front top - allows you to remove the vent. Realized there was a charcoal filter there that I had never replaced so ordered that after the fix.
- Remove two screws to pull off the front right panel (area where your microwave buttons are) One at the top under the before mentioned vent and one under the microwave on the far right corner.
- Have someone hold the panel because wiring is to short to place it on a ledge while connected or take a picture and remove connections. I simply held it while my daughter undid the micro switches.
- Carefully remove micro switches. There were two "orange" button ones so I chose the top one to replace along with the green button one that I had ordered, so I simply pulled an orange from the bottom and a green from the top latch area. You may have remove the part that holds the switches since it was a little tough with the wires in the way and not knowing how the switches stay put.
- plug in new switches and place in the brackets that hold them in place
- reverse everything you did.
Viola - a working microwave vs purchasing a brand new for several hundred dollars or having to call in a technician.I love that my young kids did this project with me and we actually got it running. Don't like to have to throw away more items at the landfill.

Semi-Handy Man

Problem would come and go. Found service schematic inside unit. Perform all the suggested tests. One possible solution was the primary interlock switch shown on the schematic and a check found the switch stuck. It would free up some times but would stick again in the open position. Ordered switch which was a simple plug in unit.

1. Removed cabinet screws (10-15?). 2. Removed cabinet. 3. Removed top interlock switch which actually was not defective. The press clip connection appeared as if it had been arcing for quite some time and the corrosion created resistance sufficient to prevent the current from getting through the switch. 4. Replaced switch anyway but broke plastic retaining clip despite every effort not to do so. Reset broken clip with super glue. 5. Reassembled cabinet and appliance is in good working condition.

I removed screws from the cover, then I removed the screws holding on the front panel. I then unplugged the connectors, and removed the front panel and broken door latch. Then all I needed to do was slide the new door latch in the spot where the broken one was and put it back together. The only thing to note is which way the yellow and white and the blue and white connectors are on the front plate (location and wire direction). All is working well, and I can open the door again. Needless to say I feel better about repairing the microwave rather then throwing it out getting another one and creating more electronic garbage in a landfill .

I had to remove the housing cover that had about 8 tamper proof screws in order to remove the cover and get into the area where the brkt-latch was. I removed the broken latch found the part I needed on your website, within a few days the part arrived. It took only a few minutes to reinstall the new part and housing cover. Everything works just fine. My guess is we saved $200 from having our local repair service center to do the same job.
