screwed in new bulb

We needed a phillips head screw driver to remove the single screw holding the light bulb cover in place.
Removing the old bulbs was a little work, because they had come loose from the sockets. We unplugged the microwave, so we could grip the sockets with a tool. I think my husband used a needle nose plier for this.
The new bulbs screwed in easily, and then we refastened the light bulb cover with the phillips head screw driver.

Turn off power supply at breaker . Replace old bulb with new bulb .

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.

Removed a couple of screws, pulled the cabinet toward me,removed & replaced filter.

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

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

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

Husband replaced the bulb

Since I have All Whirlpool appliances in the home, the only one not a Whirlpool was a counter top dishwasher that looks exactly like it could be a Whirlpool and so not to be the odd unit out, I labeled it with with a Whirlpool logo nameplate on the face of the door. Now everything matches perfectly and all in the same exact color white too.

Just measured and marked where the plate was to be located, cleaned that part of the surface, peeled the backing and carefully placed the logo name plate in place and pressed it on. Voila. Done and looks original as well. Call me the big, deep fakearooski.
