Unplug microwave! It's NOT necessary to remove microwave from above stove. Removed two Philips head screws on top front of unit to remove front grille. Removed one screw to remove control panel, letting it hang down. Found inline fuse in cabinet where line cord wires come in. Pulled out blown fuse with thumb and forefinger. Snapped in new fuse, replaced control panel and grille with the three screws. Plugged in the microwave. -Worked great! Good opportunity while grille was off to clean it and replace the charcoal filter inside the cabinet.

The power on the microwave went completely out when I went to use it, but there was no power failure for the house or neighborhood. We removed the microwave from above the oven. Took out the screws on the sides and back of the microwave and slid the top back. The line fuse was located on top unobstructed, NOT behind the button panel like some microwave models. As the appliance is over 20 years old the line fuse was quite old. It was really hard to pry it out of its holder and actually broke. I used a vacuum to suck up the dust and glass and it was easier to get out the ends once the middle broke. Popped the new line fuse in, slid the top back on, put in the screws and put the microwave back in its compartment above the stove. Good as new!! We were about to spend money on a new microwave, but thankfully I came across this site. So happy I did!!

This repair was really easy. The part that took the most time was taking it down from it's compartment above the oven and putting it back up there once repaired.

I had a son put in the new light bulbs. Rather simple

Pro tip! Check how many bulbs you need before ordering. Mine only needed two. I got two. I suspect I’ll buy a new microwave before new bulb burns out again. Ordering/delivery was fast. No need to have spare on hand.

Remove from cabinetry, take cover off and had a very difficult time removing the plastic form that has the switched in. Replace the lowest of all the switches, and then again very difficult time getting the plastic form back in. Some of the plastic even broke during the process but not any that could prevent it from working as it did before. I had ordered a fuse, 2 packs of 2 switches as there are 3 switches but only had to use 1 to get it working again. Tested after switch install, put the cover back on and reinstalled in the cabinet.

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.

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.

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

1st I removed the screw and took the old cover cavity off. I put the new cover cavity on and screwed it in. It was very easy and such a relief to have it working again. The part arrived in 2 days and we were so pleased with your website.

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?

It literally took me longer to unpackage the fuse than to install it. I removed the outer shell by unscrewing the five screws, lifted it off and set it aside. The old fuse was readily visible so I pulled it out and put the new one in its place. I set the shell back on and replaced the screws. I plugged it in and ran it for 30 seconds while still in the shop just to make sure that solved the problem and presto - it worked like a charm. A $20 part saved me from having to purchase a new microwave (sadly, I had to break the news to the wife).

My wife was pushing a few buttons with her knuckle (hands were full)and the microwave just turned off. Just like we had blown a breaker. First I unpluged it. Then I removed the phillips screws of the front panel, and found and removed the ceramic fuse. 3 days later I received the new fuse in the mail, and put it in. I plugged the microwave back in and it works great.
