KHMS155LSS0 KitchenAid Microwave - Instructions

Very easy and fast. I wished that I could just replace the panel door instead of cleaning it everytime. It was easier and quicker to replace the door than it was to clean it.

The old grill had already been removed so the new one fit right in and it was only a matter of tightening the 2 screws to hold the new one in place. Simple. Looks great. No one will ever know it was broken.

UNPLUGGED IT
Remove 2 screws on top of the unit holding the grille in- remove the grille
Remove the one screw at the top of the display and tilt the top of the display towards you.
At the bottom is a hinge that slides up to be removed- leave the screw in place.
The conector for the keypad is a ribbon connector that is attached to a black connector about 2/3 of the way up the circuit board- to release the ribbon cable the highest end of the connector has a plastic release clip that you can bend with your fingernail allowing the long edge of the connector topivot about the (lower) hinged end. Not hard to do just don't force it.
Do not remove any wires-remove the screws holding the circuit board on (2 I think) at the bottom.
The top of the circuit board is held in by sheet metal features in the housing- mine were a bit tough but its obvious how to remove it.
The keypad/exterior sheet metal & display assembly should be free now- support and place display up on a work surface.
To remove the current keypad CAREFULLY pry around the edge/junction of the ext sheet metal and the keypad. The keypad is held on with adhesive and will require some effort. Also the keypad extends slightly under the ext shett metal so it will be a pain. the goal is to start it peeling w/o damaging the sheet metal around it.
To remove the remaining adhesive (& paper) use denatured alcohol.
The new keypad is made to go under the ext sheet metal but it isn't possible to install it this way. I trimmed the edges of the new keypad so that it would drop in. You only get one try installing the keypad so make sure it fits before putting it in with the adhesive exposed.
YOU MADE IT!! Is Fixed !!

Removed the microwave from above the oven by loosening the two screws above the microwave. As the unit tilted outward lifted up and the whole unit came out all the time feeding the power cord through the cutout for the power cord. After it was out removed the cover and identified the capacitor and made sure it was discharged and removed and replaced the diode. tested before reinstalling and it heated up just fine. Reversed order and reinstalled . Very easy job maybe a second hand to help fish the power cord when installing and removing.

Remove “over the stove” unit. Remove unit shell case. Unscrew and disconnect diode. Replace diode. Re-assemble. Put unit back in place.

I read previous hints on how to replace. All suggested using tile wedges removing the inner locking piece which would likely result in some broken tabs. I tried removing this inner piece and was sure the tabs would break. I removed the three screws on the handle side of the door and used a skinny flat head screw driver between the outer skin and both the inner piece and the glass section came out together. Access to the screws attaching the handle were accessible. With the screws out, the inner piece can fall off, remove it, replace the handle and the inner piece re attaches with no breakage.

Very simple, just removed the screws and plates from the top of the microwave and reused the screws to secure the new piece.

Cracked panel door cover

Really easy I just replace the panel door. It was easier and quicker to replace the door than it was to clean it.

All you have to do is unscrew the clamps, remove the broken plastic pieces of tabs, fit the new grille into the slots on the bottom and put the two screws through the clamps at the top.

Part came in 24 hrs w/ no special "fast shipping requested" . Old door pried off fairly easily using a stiff but thin butter knife. Putting new door on was easy but only with 2 people: one person holding the handle side open and the other handling the new door. Fit the new door on the hinge side first and slowly push top and bottom edges inward until clicks are heard as the individual hooks engage the frame. When done, go back along each top and bottom edge to be sure all hooks are engaged and no gaps occur btwn door and frame. Trying to do it alone with no one holding the door open and steady would have been difficult.

I was able to buy the mounting bracket for a very cheap price and was able to instill it in my kitchen with ease.
Thank you

I removed the broken tray and ring-turn and replaced it with the new
Service was fantastic, parts were ordered one day and received the next

Washed the glass tray and put in the microwave oven. Easy..

Wonderful service, the part arrived 3 days later and it took 10 minutes to re-install the vent. By just remove 2 screw to take out the old part and re-installed the new one.

PartSelect website indicated replacing the high voltage power supply diode is the solution for "no heat" 99% of the time, but the diode was OK. There is more info at the website concerning the case of "loud buzzing and no heat" indicating the magnetron needs to be replaced. As an electrical engineer with knowledge of microwave components, this was also my best guess. However, getting to the magnetron is not the easiest job, but it's not impossible. You also have to be careful to bleed off any charge stored on the high voltage power supply capacitor. Luckily, I found my KitchenAid service manual tucked away inside the unit since I couldn't find it online.
