KHMS1850SSS2 KitchenAid Microwave - Instructions

Put s pot under were you take the screw out.If you drop it you can get it easy

Don't waste your time with other parts stores online. Partselect sells quality parts and they arrived 2 days early. I purchase a door switch from another online store and the switch was defective.

I just had to remove the screws, and the broken parts of the old grill vent (plastic part that sheared off) and put the new grill vent in place and use the existing screws to attach and that was it!

Super easy.

Remove the two screws to the plastic vent strip at the top of the unit. That exposes a metal cover (upper right) held in place by two more screws. (Found that removing the screw holding the key panel in place and moving that out of the way made for more work room) Remove the metal cover. The HV diode (visible) on one end is secured to the chassis by a screw. The other end is fitted to the HV capacitor. So unscrew one end and pull the HV diode off the capacitor. The replacement fits on like the old one came off. Very simple repair. But it would be safe to short the capacitor terminals to the chassis first. Noticed that it appeared the sparking was caused by the HV diode's outer casing being worn by the asbestos covered wire next to it and laying against it. I made sure the two were not touching, before putting the covers back on. Also, the problem started with an occasional spark when the MW started. It quickly deteriorated to a full, non-stop electrical sparking. You can hear it, smell it, and see it through the top vent. You don't need to remove unit to work on it.

One Phillip's screw to remove glass on bottom of unit. Pull old bulb out & insert new bulb. Replace glass & screw.

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.

Unplug the microwave. Removed the glass tray, the roller ring, and plastic piece that sits on the motor shaft from the inside of the microwave. Remove the 12 Phillips head screws from the bottom of microwave, let the bottom hang down on the mounting hooks at the rear of the microwave. Remove the 2 torx screws from the mounting bracket under the microwave lower the turntable motor remove the two leads. Transfer the rubber washer from the old motor to the new and reassemble and test. It took longer to write these instructions than it did to do the job.

Hint: if the microwave is over a stove lay a towel across the stove to catch any screws that may fall.

Good luck and enjoy your fully functional microwave!

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

The replacement part was identical to that of the original microwave and arrived in perfect condition.

The repair was extremely simple - too screws and a "snap" and it was done.

Couldn't be happier with the results. Thanks, Part Select!

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

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.

Replaced bulbs easily.

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

Unplug appliance. Remove total of 7 phillips screws from sides and front of bottom panel . Panel front drops down, remove one socket screw and socket. Now have access for lineman' s pliers to unscrew bulb base. Reinstall socket, replace bulb and 7 panel screws. Restore power.

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