MT4110SPB3 Whirlpool Microwave - Instructions

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

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.

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

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.

Remove outside cover of microwave.Note that there are 3 unique security screws that you will need a special screwdriver to remove. There is a YouTube video that shows how to install new part. Although this was a lot cheaper than buying a new microwave the cost of $57.00 plus shipping for this 3 inch plastic part was ridiculously expensive.

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.

Replaced the diode (aka wire-vltge) in the HV circuit after removing cabinet cover using both the secure torx screw drvr & phillips head screw drvr. The hardest part of the job was finding the secure torx nut drvr tool on the internet & purchasing same.

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.

Took off the outside metal cover determined what the problem was immediately saw the broken latch ordered the new one received in 2 days snapped it into place the door opened then replaced the outside metal cover good as new.
