MH1150XMS3 Whirlpool Microwave - Instructions

Didn't realize this part had two tabs with reinforced screwholes in it. Those obviously had snapped off at some time in the distant past, and I had always removed the grille for cleaning carefully and washed it by hand and replaced it. The clean freak moved in and took this out WEEKLY and all the other tabs were eventually cracked and made the grille unusable; it kept rattling and falling out. When I got the replacement I noticed the broken tabs and replaced the item in a few minutes after removing the debris of five or six tabs and finding a Philips head screwdriver for the apparent screws (in fine shape, they were!) and tab remnants. Good fit, looks like new. Now hopefully the clean freak won't find my screwdriver next week.

Very easy to replace. A short ladder provides easy access to two small Phillips screws on the top of the existing grill.
Remove and keep these screws to re-use.
Remove old cover and discard.
Fit tabs on the bottom of the new cover into position on microwave and press entire cover securely in place matching the screw holes to the existing microwave.
Replace small Phillips screws securely.
Step back and admire your microwave!

After taking the three screws out of the side of the door, I actually had to get help from my Dad who came over and was able to pry the top corner of the door out of the casing. I was afraid I was going to break the door. Once he got the door pried apart, I was able to replace the handle, clean the entire door and quickly snap it back into place and then replaced the screws.

We took a chance on the less expensive black Whirlpool vent grille as I found online that it would fit our stainless steel Kitchenaid microwave. My husband was able to pry the stainless cover off the broken grille and snap it onto the new black one. Then just screw in the top screws to secure. We are very happy with the stainless/black of the new setup. It goes very well with the stainless/black of the cooktop and oven.

replaced the socket per recommendations on this web site. this did not correct the problem.

First, we had to clean up all the interior surfaces, which was just cleaning. There was no internal damage. Then, just setting the center connector, rotary rollers and glass plate. Simple

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

Ordered a new motor. Removed the outside trim of the oven-microwave combo. 2 screws at the bottom of the trim. Removed the screws that held the combination micro and oven unit in place. Removed the top and bottom black plastic grill of the microwave. 3 screws each. Pulled the entire unit out about 1 inch exposing the screws at each side of the microwave that hold it in place.
Snapped off the top control panel which exposed the wiring connecting the control panel.
Unplugged a couple of wire harness units to free the control panel.
Be sure to label the units to know which goes where during reassembly.
Remove the microwave unit from the housing and place it on its side.
Remove the metal plate that houses the motor. 4 screws hold the motor in place. Disconnect the 2 wires from the old motor and you are ready to install the new motor. Be sure to TURN OFF THE POWER to the unit at the breaker box and remove the turntable from inside the microwave.

PartSelect was the only company to show that the part came in 3 different colors. The grill vent was used to replace a cracked vent. It was simmple to slip in the new vent,but be sure to save the existing screws that holds the vent in place

Placed to new grille on the microwave and attached
with the screws.

Removed retaining screws and broken parts; inserted new grill and screws. Fin!

removed old vent and replaced by snapping in and two screws inserted into right and left top connections.

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!!!)

The most difficult part was getting the old screw out of the top of the grille. Once that was accomplished, the rest was easy as can be. I would highly recommend your service - very good! Thank you!

Easy to do. Remove the old screws where the tabs had been broken off. Install new vent and replace screws. MAKE SURE THE TABS ON THE BOTTOM ARE IN THE SLOTS.
