MT4155SPQ4 Whirlpool Microwave - Instructions

Just took the plate out the packaging & rinsed,dried and put in the oven. I was so happy I found it @partselect online& it came in the next day or two. Will definitely use them again. It was a fraction of the cost from local parts store.

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.

remove 4 screws from top, front louvered panel snaps out. remove 1 screw from top of keypad, keypad pivot's forward and can be removed. There is a white mounting bracket inside left. Remove two screws, one top and one bottom, bracket lifts up and out. 3 sets wires are attached, mark them with masking tape, top, center, bottom and pull out plugs. They can only attach one way. Using a very small screw tip, lift plastic latch from switch, it rotates out and is removed from the pivot pin. reassemble in reverse order after switches are replaced

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.

Had to remove 3 screws that held the case in place,it removed easily. The control panel that the door latch was locked into required removing two screws and then lifting up slightly while pulling forward. This allowed enough room to put the new door latch bracket into place. Then re-assemble in reverse order. Total time about 30 minutes.

This plastic door latch bracket controls the door opening. Ours broke after 7 years of use. Probably just the plastic fracturing after years of use. Hardest part is finding the special driver to unscrew the housing around the microwave so that you can get to the control panel. Ask for something that looks like an allen wrench with a hole in the middle. I took a picture of the screw in the microwave and brought it to a big box store and asked for the correct driver. I have a feeling that a "real" hardware store (like Ace or TrueValue) may have been able to just direct me to the correct screw driver but I'm cheap so I though a big box store would be less expensive for a tool that I may never use again. Once you get the correct screw driver, opening the microwave is pretty easy. MAKE SURE THE MICROWAVE IS UNPLUGGED BEFORE YOU GO ANY FURTHER. There are a number of these "special" screws (4 to 6) and some regular screws to remove. Once you pull the housing off the microwave look at the release latch inside (behind the release press plate). You should be able to jiggle it out especially since it is probably broken on one side. Be sure to find and remove all the broken pieces. Mine had just the main latch and a small piece that broke off. Pull it out and you are ready to put the new one in. It is a little difficult putting the new latch bracket in. Try inserting one side into the holder hole and very gently pressing the other side in. Be patient; with a little pressure it will snap in. Then you simply put the housing back on, put the screws in and every thing should work. $20 bucks for the part and a half hour of work (after you find that special screw driver) is much better than buying a new microwave. Good luck!

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.

Removed the four face plate screws and set it aside. Then I removed the three screws holding the base plate to the wall mounting. Removed the wall plug and lifted the microwave out. I then removed all the screws holding the cover on the microwave and pulled the case to the rear This left the door latch accessible. Since the old latch had broken and fallen off, I just had to figure how the new one was to be installed This was very simple to figure out and it took me about five seconds to put the new one in.. Be careful when installing because all the parts are plastic and susceptible to breakage. I then reinstalled the microwave cover and after plugging it in ,pushed it into the wall cavity and put all the screws in to hold the oven in place. I next installed the face plate and every thing was in working order, A very simple project.

I received my glass cooking tray so fast but when I try to put in the microwave did't fix was to big,I call you today to return and very nice lady help me and told me I need to call whirlpool and explain them and already order again thank so much for all your help you have very nice people in customer service. Thank you so much again. !!

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

Placed in micro Great sevice. Thanks

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.

Great!! I set the new tray into the microwave and was done! This site has the best service I have ever seen! I'll be back when something else breaks, it is just a matter of time.

I simply went on line to Part Select, placed my order, made payment, and was astonished to see the package with a new dish sitting on my doorstep the next day.Great service.
