MH7140XFQ1 Whirlpool Microwave - Instructions

removed two screws,lowered the glass shield,removed the burned out bulb and replaced it with the new one. I ordered the bulb from parts select and recieved it two days later. It was a pleasure to deal with them, and certainly use them again.

Read some instructions and easily found the fuse. Replaced it. Still didn't work. Took control panel off to check door switches. Nothing I read mentioned a second fuse. Tested and it to had blown. Ordered another one. Popped them in. Done.

I had some difficulty removing the glass plate because of the awkward (upside down) position of the screw that retained it. After replacing the burned out bulbs and replacig the glass plate the problem of replacing the screw involved my dropping the thing several times before I got the screw threads to catch. I got a screw thread to cat ... Read more ch enough to hold the glass plate in position and left it at that.

I made a video. There were specific instructions to note which needed to be explained. Interested?

The hard part was trying to find the light bulb locally. The locally sold light bulbs were either too long, not dual element or not powerful enough. So I ordered the light bulb straight from PartSelect. When it came time to install the new light bulb I carefully removed the screw holding the plate in position so as not to loose it in my ... Read more gas stove. I needed the mirror to line up the light bulb and screw it in. Once it was in I verified operation and closed up the plate being careful not to drop the screw into my gas stove. Problem solved.

I found the part number for the mount on the appliances company website. Once I had that I visited a few sites looking for part. This site was easy to use and priced right, so I ordered. A few days later the product arrived as promised and worked perfectly for the install.

I used a Google search to show how to access the area behind the front panel. There was a folded paper copy with a schematic and wiring diagram in that space.Then I used a multi-meter to determine which of the THREE micro-switches was causing the problem. I called your help line and ordered a replacement switch. The switch was delayed ... Read more in transit so your agent credited me with the cost of shipping.

When the part arrived, it had three terminals instead of two as shown in the on-line picture but that did not cause any difficulty in using it. It took about 20 minutes to remove and replace the old switch.

All seems to be working well now.

Finding which of the THREE switches was the problem was the most difficult part of the repair. All three "clicked" but the defective one did not click as easily. It needed to be depressed more than the door latch can would provide. Old age?

Instead of telling you, i have question do you have any instructions on how to do the repair. It would have helped save time on the repair.

This job took longer then it should have, becasue I did not start right in the begining. I did figure it out quickly after the wrong start.

I ordered the part according to the Model number, inserted the part very easily, (and I am soooo challenged in that area) and now it turns again. :)

This is not easy to do. I done it before to replace a broken window and it was a real bitch. I considered buying a new door rather then do it again.All I wanted to do was tighten two screws that hold the handle.

I turned off the power to the oven at the breaker. I then removed the side trim pieces by removing the screws located behind the lower oven door. I removed the plastic trim pieces above and below the microwave oven and removed the control panel and slid it into the opening above the microwave. I located the two screws securing the mic ...

The microwave section was the easily slid out, turned on it's side where the turntable motor was accessed by removing the access panel. I pulled the old motor, checked resistance and it matched the new motor. I then checked the old motor by applying 120V to it and it ran FINE! I thought I had the wrong part, but decided to install the new motor anyway. I did, secured the access panel and replaced the microwave in the frame. I reconnected the wires and secured the control panel and tested the microwave...and the turntable works!
