MT4110SPQ4 Whirlpool Microwave - Instructions

The push button door latch had broken on my microwave. After digging into the unit-which was the hardest part, getting the shell off and getting at the control panel, I was able to see an interior latch part that had one side of plastic broken off. 40. repair piece later and I was able to plug that in, put it all back together and it works, although it does not feel that solid or that it will last a lifetime. Glad I was able to fix instead of calling a repair guy.

Took microwave out of builtin cabinet with 4 screws.
Put microwave on center island and removed cover.
Tested interlock switch with volt meter and it appeared ok so I put my kit back in box and sent back.
Took out magnetron unit and replace with new part.
Put cover back on and test.
All is working and installed back in cabinet. Two weeks later all still working great.

Watched a you tube video prior to installing new switch. Followed the video which gave me confidence i was up to the task. After removing the touch pad I found my design was not exactly like the you tube model but I found the defective switch, replaced it and put the microwave back together. Works great. Again watch the videos

It seems that the heat of the microwave cracks the part over time. It is a very simple installation.

Using fingers, the old turntable roller guide was pulled up off the motor shaft. The plastic roller guide shaft coupler was found to be broken, allowing the motor shaft to spin without turning the roller guide. The hole in the floor of the oven was inspected, and no broken pieces were found which could interfere with the new roller guide. The new roller guide was then gently pressed down over the motor shaft. Very easy.

Removed M/W oven case/cover. Identified part needed. Found part online with in 2 minutes, ordered new door latch actuator, installed with part arrived within two minutes, reattached case/cover, reinstalled M/W.

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.

Replaced Door latch Bracket.
Filed a bit off the bracket connection fingers so to fit into the slot.

took out plastic piece under plate (that was broken) and placed new one in the hole. No tools req'd. Works like new.

Ice covered the top back of the freezer compartment. This did not allow the cold air to move up to the fridge. Complete defrosting (36hrs) fixed the problem. There was a lot of water, from ice inside, that was not visible. We realized the freezer drawer must have been left cracked open. Thanks so much.

1.ordered the part 2.during wait time for part,i epoxied the broken ear of the door latch bracket back on to the broken part.3.waited 24 hours for epoxy to set,4.installed the repaired part.5.reassembled the microwave and reinstalled in the wall unit.6.days passed and the ordered door latch bracket finally arrived.7.we are using the microwave daily with the repaired door latch bracket,but we will keep the new part in reserve,just in case!JUST CAN NOT DO WITHOUT OUR MICROWAVE!

The tip on the end of the latch broke off, so I had to carefully pry it back in without breaking the new piece. Took a few tries, but got it.

All the electrics worked on Amana microwave EXCEPT for the cooking function. Inspected the control board and found the upper switch on the door interlock was burnt. Installed new switch in minutes and everything now works fine. Unfortunately, had to purchase expensive two switch "kit" although only one switch was kaput. PartsSelect mailing was SUPER fast. Thanks for looking, Scott

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.

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).
