KHMS155LBL2 KitchenAid Microwave - Instructions

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.

Looked up symptoms on parts select website. Ordered mag and diode. Very easy to take micro off the wall. Easily removed screws holding the skin on. Found diode. Really didn't need to replace it but since I had a new one (fairly cheap), just did so. Diode only installs one way. Can't botch it HOWEVER, MAKE SURE THE ONLY PART OF THE DIODE TO TOUCH THE GROUNDING POLE IS THE SCREW DOWN LEAD. IF THE OPPOSITE END LEAD, THAT WHICH IS THE PUSH ON TERMINAL, TOUCHES THE GROUNDING POLE, YOU'LL GET ARCHY SPARKY. The magnetron goes in very easy. Simply pay attention to how you removed it and reverse that process installing the new one. There are easy to use YouTube videos that show magnetron replacement. You can do this easily and save your microwave and $$ while doing so.

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.

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

Loosened but did not remove screws that held up microwave over range,removed grill on top by loosening screws that held grill in place.removed small mesh grill on right side of microwave, this gave me access to capacitor ,diode is connected from one lead of capacitor to a metal plate ground,Disccarged capacitor to ground by shorting terminals to ground using a thick insulated screwdriver.Since the diode was screwed to the top of the metal plate I cut it out with a pair of side cutters .I then connected the new diode to the capacitor with my long nose pliers and groonded the other end to a more accessible part of the metal grounding plate.I then replaced all parts in reverse order.Works like a charm.

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.

easy to replace, just the same as cleaning the turntable and placing back in the micorwave;

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

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.

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.

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

Door handle: open door, remove screws holding door insert and insert putty into door insert to access door handle screws. Screw in new handle and snap door insert back with screws.

Vent grill: remove old grill and replace.

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.
