MH1141XMB1 Whirlpool Microwave - Instructions

I ordered the part according to the Model number, inserted the part very easily, (and I am soooo challenged in that area) and now it turns again. :)

I turned off the power to the oven at the breaker. I then removed the side trim pieces by removing the screws located behind the lower oven door. I removed the plastic trim pieces above and below the microwave oven and removed the control panel and slid it into the opening above the microwave. I located the two screws securing the microwave into the frame and began sliding it out. I had to disconnect a small wiring harness and two wires from the microwave that were attached inside the opening above the microwave. The microwave section was the easily slid out, turned on it's side where the turntable motor was accessed by removing the access panel. I pulled the old motor, checked resistance and it matched the new motor. I then checked the old motor by applying 120V to it and it ran FINE! I thought I had the wrong part, but decided to install the new motor anyway. I did, secured the access panel and replaced the microwave in the frame. I reconnected the wires and secured the control panel and tested the microwave...and the turntable works!

Replaced bulb by: 1 pulling plug on microwave to make sure not hot - no power; 2 used needle nose pliers with head part about same size that fit inside of socket; 3 opened pliers and held firm against broken metal part; keeping pressure of pliers against broken metal part of light bulb, slowly unscrewed the broken part from socket using firmly held opened pliers. The rest was a cinch...just screwed in new light bulb, plugged in microwave and viola - there was light once again.

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

Removed screws holding the broken grill tabs with a phillips screwdriver
Removed broken grill and all broken tabs that fell into the vent area
Cleaned area where the new grill was to be placed
Inserted new grill onto the appropriate tabs and tightened the screws

BE CAREFUL as the tabs on the grill are thin and fragile when you insert the new grill don't force it into the slots, I used a knife as a way to slide the grill into place.

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.

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!

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.

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.

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.

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.

-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.

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.

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

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