MMV5208WW1 Maytag Microwave - Instructions

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.

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

Husband replaced the bulb

Replaced the supports and rack.

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

Based on other similar posted repairs, I purchased the bottom switch. Upon removing the control panel to replace the switch, I found the blue 22 gauge wire was broken at the spade terminal. This wire had been crimped to the terminal along with a 14 gauge wire. Apparently the force to crimp the thicker wire weakened the smaller wire at the terminal. I stripped the end of the small blue wire and reattached it to the thicker wire using a solder iron and solder. The repair fixed the problem.

Changed out turntable motor

I removed the microwave to install a back splash and found the support edge on the backplate had broken off and was missing. I searched for parts for the microwave and found them on PartsSelect.com. Easy to order, and was shipped promptly.

Once the part arrived, install was simple, lining up the existing holes. The only hard part was setting the microwave up on the bracket due to the weight and awkwardness of the microwave.

Overall a very simple repair.

On top front of the microwave are two Philip's head screws holding the rail on. Remove these screws and the rail snap out the old filter (noting the dark side down) then snapping the new filter in. Replace rail. 10 to 15 minute task.

After removing the over-the-range unit (no small feat!) I had to figure out how to open the case (good puzzle!). Capacitor had already discharged, so it was very easy to reach in, pop the old fuse and install the new one! As per your advice, I found out I was a "28%-er"! Upon re-installation, the microwave "sprang to life"!! Thanks, "Part Select"!! I was already shopping around for a new machine! (Now if you could only tell me an easier way to re-mount this heavy beast over the stove!!!)

Unscrewed glass panel, removed old bulb, cleaned glass panel and installed new bulb. Screwed panel back into place.

Removed the face plate above the door (2 Phillips screws.) Removed existing filter and replaced with the new one purchased. Reinstalled the face plate.

when I opened the back cover of microwave, the diode was kind of blackish blown, since there was light bulb and fan were still working, i thought it could be problem with any one of the components like; magnatron or capacitor or diode, so first replaced the diode and mica at the end of the magnatron duct, there was problem with door switch as well. i fixed that too. Now it is working. It cooks bit faster, Wondering why?
