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.

Motor quit working but light and timer still worked.

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.

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

hardest part was taking the microwave down off of the wall to gain access to the diode. Thought if was the transformer but ended up being just a blown diode. remove and replace and bench test. that part took 15 minutes . moral of the story don't boil water under the side of the microwave that holds the electric components.

I didn't have a recessed drive or bit

We got a a carbon steel but and drilled out the stews and put in regular screws. We also had trouble getting the cover back on and ended putting 2 more screws on the left side which had none. The installation was the easiest part of the installation.

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!!!

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.
