GT4175SPT3 Whirlpool Microwave - Instructions

removed microwave cover screws, unplugged motor, screwed on new one

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!

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.

The only reason it took over 30 minutes was that the unit is a built in over the stove type installation. The special Philips like screw driver which I purchased was the wrong size. I had to use a small vice grip tool to remove and reinstall these screws. The suggestion to use a butter knife to spread the slot was a good one. The delivery from part select was amazing. We were not without our micro more than a few days

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.

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

Followed the instructions that others with a similar problem had written about. Their experience was very helpful. My experience with Part Select was the best! Part recived in less than 24 hours. Happy household, wife thinks I'm worth keeping!

I started by calling a reputable service company to diagnose my problem. The repair tech told me it was the magnetron and it was a "very difficult" repair that required two people because the over-the-range unit needed to be taken down. I asked for a detailed estimate. He quoted $550 including parts and labor. After he left, I researched the part costs on this site and realized his costs were very inflated. I purchased the magnetron for $220. It arrived at my door two days later. Installation was very easy. First, I unplugged the unit. Then, while my wife was making sure it did not fall off the wall bracket, I unscrewed the two mounting screws from the top of the cabinet. I lifted the unit down from the wall and set it on the kitchen counter. The shell needed removed from the microwave which involved about 20 screws. This provided access to the magnetron on top. The magnetron is secured by five screws and a plug. I unplugged it, unscrewed it, and removed the old part. Then, I installed the new magnetron, and tested the microwave to make sure this did the trick. It worked. I put the outer shell back on the microwave and cleaned the microwave. (This is a great opportunity to clean the areas you do not typically see!). I then remounted the unit and plugged it back in. Saved myself a bit of money so I took the family out to dinner and a movie to celebrate. Microwave was in working order for heating up left overs the next day! Thank you!!!

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.

Well, first of all I luckily picked your website after it had broken that day, got all the info, ordered that day, and got it the NEXT day and my husband fixed it that day. VOILA!! That may never happen again, but that was the easiest thing we have ever done. You can better bet we will be ordering from this website again,as well as letting others know about it. Very impressed, and yes, this is real.

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!

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).

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.
