Turntable on Maytag MMV5100AAW Stopped Turning

Symptom: Turntable stopped turning. Was able to remove the glass tray in the microwave and the little cam that drives the glass tray was barely turning. Control on microwave to turn the turntable on/off was working as evidenced by the cam not turning when I turned off the turntable. When I turned the cam manually, I could feel the motor turn so I knew the CAM and motor shaft were not stripped.

Repair Procedure:
1) Unplug the microwave.
2) Remove the 4 screws from the bottom of the microwave while holding the bottom cover so that it does not suddenly drop. It is not very heavy so you are fine to hold it with one hand and unscrew the screws with the other. Don't drop it as it has a glass lens for your lights and two light bulbs that light up the cooktop below.
3) Swing the front of the cover down slowly. You wil notice that the back is held in by tabs that slide into the back of the microwave. The bottom cover comes off very easily with some forward motion to dislodge the tabs.
4) Now look up under the bottom of the microwave(assuming your microwave is mounted over the range like mine) and you will see the turntable motor (GEAR MOTOR) in the center.
5) Carfully remove the two wires from the motor by gently working the connectors off of the motor using neegle nose or regular pliers. Don't grab the wires as you may pull them out of the connectors. Work with the connectors on the motor terminals. You will find the job much easier to do if you also remove the wires from the light housing. This will allow you to set the bottom cover aside and will give you greater access to do the job.

NOTE: Now is a great time for you to clean the filters, filter slots, bottom cover, and the light lens. A lot of grease can accumulate on the bottom of the microwave if it is mounted over a range (like mine). If you remove the light assembly, you can clean the cover, filters, and and light lens in the sink. Make sure that you dry all components thoroughly before re-assembling.
6) Make a note of which wires go to which terminals on the motor and the lights.
7) Remove the two screws from the motor and remove it. Note that there is a little plastic insulator film, a very thin washer and a bushing associated with the motor. You will want to re-install these with the new motor. Replace the motor with the new one being careful to put the other pieces back in place as well. Note that the little black turntable cam has a tab on one side so if you want to put it out of the top, you will need to tilt it slightly.
8) With the motor and associated parts back in and secured with the two screws previously removed, re-attach the wires to the lights and motor.
9) Replace the cover and screws and you are done!

This repair is much easier than these steps would suggest but I wanted to be thorough.

I called Maytag and they refused to sell me the part because they said it was dangerous for the user to replace it - rubbish. As long as you kill the power to the microwave and confine your work to the bottom of the unit as described, you will be fine. Maytag wanted to send out a repairman at $80 just to show up. I did the entire repair myself in about 15 minutes for about $40.

Ordered the new vent-grille air cover on a Saturday before Thanksgiving. The part arrived on Thanksgiving week (no mail delivery on Thursday) on Friday.

The installation was a breeze! First I removed the two screws that hold the element in place. I then pulled the element off. I inserted the new vent-grille cover and replaced the two screws. The entire replacement/installation took less than 10 minutes with the one Phillips screw driver.

I would definitely use PartSelect.com again for all of my part requirements. I am very pleased with the service. Thank you!

Very easy to remove the bottom on the Microwave. Make sure you have unplug the electrical cord. Take the screw driver remove three screws and use your pliers to remove the two wire terminals. Reverse the order and you have a new microwave that works great. Also if you are not using the tray in the microwave remove it as it heats up and takes away from the item you are trying to heat. Good luck to you!!!!

Replace the capacitor and the fuse. Then it works again. Part arrived in an open plastic bag with scratch. It looked like a returned part, but it works fine.

The microwave would blow the fuse immediately when trying to use.

I replaced the large capacitor (.95 uf). Much of the shell (casing) has to be removed and the capacitor is hard to get to. It is housed in a very inconvenient place. Because of the unfamiliarity of how to access the capacitor it took about an hour to get to it. After receiving the new capacitor it only took about half an hour to install it, re-assemble the microwave, and re-install under the cabinet. Of course a new fuse was required.

Maytag Microwave UMC5100AD fixes

  • Customer: Biao from Houston TX
  • Difficulty: Easy
  • Time to Complete: 1- 2 hours
  • Tools Required: Screw drivers
  • 1 of 3 people found this instruction helpful
My Maytag Microwave UMC5100AD was suddenly broken in 1 second when I heated food last time. Then no clock, etc, seem the fuse broken. to fix it, the most difficult part was how to remove it from the wall trim. Finally got it out. Then went HomeDepot to get the same fuse, replaced and used it, burned again. Then I searched online and ppl said the capacitor might be the one. I took it out and measured it, yeah it indeed was a problem since it's not open. Then I order the capacitor from PartSelect about $32. After 3 days I got it and installed it. Done. Sure need to put the Microwave back to wall trim. That's it. Saved about $500 buck if I buy a new one plus labor to install it. Thanks

LACK OF HEATING

  • Customer: Benjamin from Upland CA
  • Difficulty: Easy
  • Time to Complete: 15 - 30 mins
  • Tools Required: Pliers, Screw drivers
  • 0 of 0 people found this instruction helpful
First I removed the top vent, this exposed the control panel holding screw - I removed this screw lifted to unhooked and I swing the panel to the left - disconnect the harness attached to this panel and be able to removed it out of the way, then I removed a fan assembly located on the back of the cavity -- this exposed the capacitor - carefully disconnect the capacitor ( I was a little concern about this because is a high voltage cap) I used isolating pliers, just in case energy was stored, that's it. Put everything back and microwave start working again. I think I still need to find out why the fan is not automatically start running after I start the microwave and the internal light only goes on sometimes when I open the door - can anybody help on this?

After unplugging the microwave and removing the screw, I removed the old bulb and put in the new one!! I made sure it was in securely and the difference in the light was awesome! I use this light when I bake bread and let it rise inside the microwave, but DO NOT turn it on. The heat from this light helps the bread to rise properly!!
