KCMS1555SSS1 KitchenAid Microwave - Instructions

Took microwave out of builtin cabinet with 4 screws.
Put microwave on center island and removed cover.
Tested interlock switch with volt meter and it appeared ok so I put my kit back in box and sent back.
Took out magnetron unit and replace with new part.
Put cover back on and test.
All is working and installed back in cabinet. Two weeks later all still working great.

Unplug microwave! It's NOT necessary to remove microwave from above stove. Removed two Philips head screws on top front of unit to remove front grille. Removed one screw to remove control panel, letting it hang down. Found inline fuse in cabinet where line cord wires come in. Pulled out blown fuse with thumb and forefinger. Snapped in new fuse, replaced control panel and grille with the three screws. Plugged in the microwave. -Worked great! Good opportunity while grille was off to clean it and replace the charcoal filter inside the cabinet.

Watched a you tube video prior to installing new switch. Followed the video which gave me confidence i was up to the task. After removing the touch pad I found my design was not exactly like the you tube model but I found the defective switch, replaced it and put the microwave back together. Works great. Again watch the videos

discovered upon further inspection the the plastic shaft coming out of the turning motor was melted. Had to stop repair and order that part

Removed M/W oven case/cover. Identified part needed. Found part online with in 2 minutes, ordered new door latch actuator, installed with part arrived within two minutes, reattached case/cover, reinstalled M/W.

Remove outside cover of microwave.Note that there are 3 unique security screws that you will need a special screwdriver to remove. There is a YouTube video that shows how to install new part. Although this was a lot cheaper than buying a new microwave the cost of $57.00 plus shipping for this 3 inch plastic part was ridiculously expensive.

Replaced Door latch Bracket.
Filed a bit off the bracket connection fingers so to fit into the slot.

Remove from cabinetry, take cover off and had a very difficult time removing the plastic form that has the switched in. Replace the lowest of all the switches, and then again very difficult time getting the plastic form back in. Some of the plastic even broke during the process but not any that could prevent it from working as it did before. I had ordered a fuse, 2 packs of 2 switches as there are 3 switches but only had to use 1 to get it working again. Tested after switch install, put the cover back on and reinstalled in the cabinet.

I ordered the part from partselect (PS972837 Door Latch Bracket) and read all the instructions written here, very easy to do! Saves me a lot of money!

I received my glass cooking tray so fast but when I try to put in the microwave did't fix was to big,I call you today to return and very nice lady help me and told me I need to call whirlpool and explain them and already order again thank so much for all your help you have very nice people in customer service. Thank you so much again. !!

The door was not engaging the micro switches properly no doubt from 10+ years of wear. The upper switch removed fairly easily but take care not to tweak the plastic brace too much or it will snap. The lower one was the tricky one. After much examination I noticed that the trick to remove it was underneath the brace. Take a butter knife (no joke) and insert it just under the old micro switch and gently press down twisting the micro switch every so slightly til it releases. The replacements snap back in with no trouble. The microwave is working much better now, though not perfect.

Since others reported similar problems and it was just the fuse we tried that first. That wasn't the problem so we ordered the Door Interlock Switch Kit. Shipping was very fast! Our microwave had 3 switches. My husband asked how to know which one to switch. I read that one person just did process of elimination. Luckily ours worked on the first change out! So happy to have stumbled across this site and not have to buy a whole new microwave.

The only reason it took over 30 minutes was that the unit is a built in over the stove type installation. The special Philips like screw driver which I purchased was the wrong size. I had to use a small vice grip tool to remove and reinstall these screws. The suggestion to use a butter knife to spread the slot was a good one. The delivery from part select was amazing. We were not without our micro more than a few days

Had to remove 3 screws that held the case in place,it removed easily. The control panel that the door latch was locked into required removing two screws and then lifting up slightly while pulling forward. This allowed enough room to put the new door latch bracket into place. Then re-assemble in reverse order. Total time about 30 minutes.

remove 4 screws from top, front louvered panel snaps out. remove 1 screw from top of keypad, keypad pivot's forward and can be removed. There is a white mounting bracket inside left. Remove two screws, one top and one bottom, bracket lifts up and out. 3 sets wires are attached, mark them with masking tape, top, center, bottom and pull out plugs. They can only attach one way. Using a very small screw tip, lift plastic latch from switch, it rotates out and is removed from the pivot pin. reassemble in reverse order after switches are replaced
