MT2140SJQ0 Whirlpool Microwave - Instructions

The instructions on the website were incredibly easy and I saved myself a lot of headache by using this site.

-it was built in unit - so I needed to pull the decorative grill from around the outside to remove it from the wall
- removing the back of the case involved removing phillips head screws from along the side and back of the unit. the only issue I encountered on removing screws was the fact that the "torx / star" screws could not be fit with the wrench that I had (they had a pin in the center that would not allow the wrench to fit into the star). However, a pair of pliers was handy and they were removed just easily.
- I had ordered both the high voltage diode and magnetron because I didn't know which item was the problem. I grounded the diode with two screwdrivers while wearing rubber gloves to be safe. the warnings on this did the trick as it was the only scary part of the operation.
- the diode was a little hard to spot looking at the schematics, but is is found on the lower right corner of the right side of the panel and easily pulled out and replaced. I tried the microwave again to see if it worked...and it did not. So I confirmed that the magnetron was the issue.
- removing the screws for the magnetron and putting in the replacement was a dead easy and I tried the microwave again before putting cover back on. Worked like a charm. Super easy!

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.

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.

Did an online search for repairs and found PartSelect. Simple to order the part and had it installed myself less than a week later. Thank you!!

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.

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.

The door was not engaging the micro switches properly no doubt from 10+ years of wear. The upper switch removed fairly easily but take care not to tweak the plastic brace too much or it will snap. The lower one was the tricky one. After much examination I noticed that the trick to remove it was underneath the brace. Take a butter knife (no joke) and insert it just under the old micro switch and gently press down twisting the micro switch every so slightly til it releases. The replacements snap back in with no trouble. The microwave is working much better now, though not perfect.

Since others reported similar problems and it was just the fuse we tried that first. That wasn't the problem so we ordered the Door Interlock Switch Kit. Shipping was very fast! Our microwave had 3 switches. My husband asked how to know which one to switch. I read that one person just did process of elimination. Luckily ours worked on the first change out! So happy to have stumbled across this site and not have to buy a whole new microwave.

I called to make sure I was replacing the correct part. I paid over the phone and it came the next day. Very very easy process.

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.

I had purchased the wrong replacement tray from Amazon and could not find the right one on their website. Yours was exactly what I needed.

very easy just put the tray on the turntable. excellent delivery service arrived sooner then expected.
