MT4155SPB4 Whirlpool Microwave - Instructions

I ordered the part from partselect (PS972837 Door Latch Bracket) and read all the instructions written here, very easy to do! Saves me a lot of money!

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.

OMG! I wish everything in life were so easy.....The cooking tray of our 15 year old microwave cracked and I swore it'd be impossible to find a replacement. That is until I discovered Partselect.com!!All I had to do was input the appliance brand and part I was looking for, and there is was. Thank you, Partselect.com!!

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.

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).

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

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.

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. !!

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!

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.

Placed in micro Great sevice. Thanks

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.

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.
