UMV1160CW3 Whirlpool Microwave - Instructions

Two Mounting plates # PS12074431 were sent to me and both do not fit.
Model number MMV1175JZ-0
Serial number TRX-17. 24546
Manufactured April 2020
Contacted Maytag and even sent pictures to show the problem with alignment of the mounting plate not fit in the back of the microwave.

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.

Part of the support was missing. I had to remove the two switches and put them in the new bracket
Had the switches reversed and started blowing fuses. Reversed them and changed the fuse and it started working.

screwed in new bulb

Unplug the microwave. Then remove the six screws that hold the lower panel which has the light bulb cover and a couple of vent filters. The light bulb sockets are on a fixture that is connected by a quick connect electrical connector. Disconnect that and the whole panel is free to access the bulbs. My bulbs were very fragile and trying to twist them out resulted in the glass twisitng loose with the base still in the sockets. I needed to use a needle nose pliers to remove the bases and then I replaced the bulbs and put every thing back together

Husband replaced the bulb

took the front right side of the microwave off took the oldcontrol board out and install the new one apiece of cake

took a chance on this was the problem and it was...my son-in-law took it out put in the new one and it worked...saved $300

I had the help of a handyman, I'm 75 years young but not handy with tools

Just opened the door and dropped in new part and viola!

Removed turntable
Place support ring in track
Place turntable on support ring.
Easy, peasy!

Spouse just screwed in the new bulb and reinstalled the light cover plate with the two screws. Took under a minute. Works great.

I ordered a new door from PartsSelect and received it in about 7-8 days. Looked at a video on how to replace the door. Replaced the door in about 15 mins. very easy and everything fit perfectly.

Repair unsuccessful because they sent the wrong part, even after I questioned their selection. It is amazing how a company as large as Whirlpool cannot clearly indicate to the people who work for them how to order the correct part. The fault lies not in the individual who is putting the order in but with the company who cannot take the time to make sure that person is successful in completing their job. Will never buy a product from this company again.
As far as the shipping is concerned. It took forever, just to find out that the part was incorrect.
Better luck next time. right?

Unplugged the microvave, removed the phillips screw holding the right hand section of the microwave in place (Note: This screw is found by looking through a vent opening in the TOP of the microwave body.). Lifted up and out on the right hand section of the microwave. At this point the right hand section is completely unattached to the microwave body. Unplugged all of the polarized wiring harnesses and removed the screw holding the green wire to the board holder. Removed the screws holding the board to the right hand section and installed the new board. Reversed the procedure to put the microwave back together. Note: Look at and manipulate the keypad ribbon recepticle on the new board to see how to remove and reattach the ribbon, if needed.
