YMH1150XMS3 Whirlpool Microwave - Instructions

replace one of the four rack supports which was melting

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?

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.

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.

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.

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.

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.

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.

Very simple, just removed the screws and plates from the top of the microwave and reused the screws to secure the new piece.

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 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
