MH7140XFQ0 Whirlpool Microwave - Instructions

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.

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

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!!!)

Ordered the glass tray and installed it. Received the orderin about two days.

The part came very quick less than a week. The installation took less than 15 minutes.

Took out the turntable parts to ensure I ordered the correct cooking tray. Matching those with photos of related parts on PartSelect worked great. Put turntable drive and support ring in place and cooking tray went in very easily. Plan to order a second one to have on hand for this rental property.

replaced with new one

Replaced the missing tray and unscrewed a couple of screws to remove broken grille tabs and retightened the screws to hold in the new grille. Very successful and very easy. Thanks

Used hands to slide filters sideways, till they could be pried out with screwdriver or bare hands. When new parts arrived, easily slide new filters into position. In hindsight, we did not need to replace grease filter. I was able to clean one of those with ordinary dish soap, warm water, and a brush.

Removed the broken parts and screws and placed the new vent on and tightened screws. I am an 76 year old woman, so if I could do this, then anyone can! Surprisingly easy to install.

I, carefully, inserted the bottom tabs into the appropriate slots. I then rotated the vent piece up and into place under the top lip of the Microwave. Once positioned I installed the screws required to hold the piece in place. Very simple replacement. It gave me a chance to clean the grease behind the vent.

Unscrewed the remaining (2) screws that held the vent in place, placed the new grill in the tab loctators, and screwed it into place. Done...in less than 10 minutes. It took me 15 minutes to find my wife to show her what a nice job I did.

First, the screws were removed that held the vent grill to take off grill. The new vent grill was then replaced in a very short time. No problems at all.

I removed the 2 screws holding the broken vent grill, placed the new one in place and put the 2 screws back in place. Took less than 5 minutes from opening package to replacing the grill.

First remove two screws on top of microwave. Pull off old vent grill. Finally line up new vent grill (bottom edge first) then snap into place. Replace two screws on top of microwave.
