WMH76718AS0 Whirlpool Microwave - Instructions

Replaced a broken vent grill on my microwave

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.

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.

I was sent the wrong fuse by you. I had to procure a fuse in another manner. Very disappointing. The repair was simple. It just took longer because of the failure to send the correct fuse.

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

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?

I simply lifted out the glass rotating plate and inserted the new support. How complicated can that be?!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is an under the counter microwave. Simply removed the two screws holidng the vent grille on top of the unit, lift out the old charcoal filter, clean the vent fan exit surfaces then replace the filter and put the vent grille back. Be careful to not drop either of the two screws after one is installed as you will have to take the grill off and start the screw installation again unless you have a magnetic to retrieve the dropped screw. An easy five minutes at most to change.

took it to Buttermore appliance in Auburn Indiana and he changed the fan and added another fuse

Open compartment, installed bulb, closed compartment

Took the front off and behind a plate was the fuse, so I replaced it for what good that did!!!

While on your web site and looking at the three parts needed for my microhood oven, I called Customer Service to make certain the parts were correct. The three parts ordered and received were "exact" and easy to replace as instructed with one simple phillips screwdriver. Also, the total price was very reasonable. I would like to also add that the Vent Grille you sent has a much more improved support structure where the mounting screws are inserted than the original. I would, without hesitation, order parts from you in the future than from the major chain store where I purchased the appliance.

Replaced filter which came inrecord time.

I unscrewed the filter cover, replaced the charcoal filter and replace the cover. The other wire mesh filter slides right into place. You sent me the right parts for my filter replacement on my microwave. Easy install. Thanks

Poorly designed plastic grill vent covered by stainless steel held by 2 metal screws broke off with minimal pressure during routine cleaning. Easily replaced in 2 minutes with Phillips screwdriver. Partselect very helpful in ordering process. Would not hesitate to use them again. Fairly priced, knowledgeable and sympathetic help. Received part in 3 days from order. Awesome service.
