KHMS145JWH0 KitchenAid Microwave - Instructions

Take off top facing over microwave using screwdriver also protection plate for diode and capaitor. Disconnect diode from frame, bracket to capacitor then remove, disconnect wires leaving diode on capacitor for right connection, replace, rewire done.

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 D ... Read more IODE 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.

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 ... Read more 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 !!

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 ter ...

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 ed ... Read more ges 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;

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.

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

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.

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

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

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, ... Read more 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.
