MH1150XMS2 Whirlpool Microwave - Instructions

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.

It was a bit awkward because the microwave is mounted over my stove. I had to twist around and install the bulb and then replace the cover. It was a bit uncomfortable. It took me about 10 minutes to complete.

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.

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.

Removed 2 screws from top of microwave. Place new grill in place. Replaced 2 screws that were removed. What was wonderful is I ordered the part around 3 pm on a Friday. The part arrived at 9AM the next day and that was without requesting special shipment.

Unscrewed the remaining pieces of bracket slipped in new vent cover and attached with the two screws. Very easy since the web site showed where the vent attached. I saved over $60.00 doing this repair myself!

I didn't have to remove the old cover since it cracked and fell off the microwave already. I simply snapped in the new vent cover, screwed in the 2 screws and I was done. Super easy.

I removed the two screws and took off the old grill. Snapped the new grill in place and replaced the screws. This model was not shown on the list but the part fit just fine. The part arrived in 2 days! I ordered the white one and at first didn't think it matched .. maybe my microwave was bisque or almond .. but after 15 minutes of scrubbing I realized it was white but just real dirty .. lol. Now the door opens without the grill falling off. Easy fix.

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.

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.

-leave door attached to microwave.

-remove three phillps screws from end of door next to handle.

-use two flathead screw drivers to pry apart the outside cover and unsnap the two sections of the door. Start in the top middle.

-use phillips screw driver to remove two screws holding handle on.

--handle has an up and down side, attach longer side to the top of the door.

-snap two door pieces back together.

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.

Used a phillips screwdriver to remove 4 retaining screws located on the top leading edge of the unit, just above the door. Note the screws on the far left and far right are shorter than the middle two. After removing and cleaning the plastic vent, the small, square charcoal filter is revealed in the center, and is easily removed (noting its installation position first!). Take advantage of the opportunity to thoroughly clean the inside using a cloth soaked in degreaser before replacing the filter, the vent, and the 4 screws.

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

Is there an instruction video?
