I decided the door switch was the problem because 2 problems happened at the same time. I removed the 4 screws for the top outside cover and the 1 screw that held the control board. After removing the control board screw, I lifted it up and removed it. This gave me access to the 3 door switches. I then removed the 2 screws that held the plastic piece that holds the switches. This made it easier then to replace the switches.

tested all 3 of the door switche for continuity, the top switch was faulty, replaced it,for approx $4.00 and saved a $350 dollar microwave.

Had a Trim Kit to remove, just 2 screws on the front to pull it out. Had to remove the tamperproof screws on the back (the outer shell is held on by them). I had to goto a local hardware store as nothing anywhere mentioned I needed this special tool (NOTE!!!!!!!) The bottom had normal phillips head screws. Note: I did not take the entire shell off, just bent it enough so the base plate could be pulled out. This exposed the motor, which strangely enough is NOT held in by any screws, just notches it slides in. Took the old motor out, came out VERY easily (only 1 plug to pull out). The new motors flange tab was bent a little bit so I had to use pliers to bend it back flat so it would fit in the notch on the bottom of the microwave (very easy). Overall A bit difficult due to special tool needed 9at least for me)

Over the stove microwave installed in top cabinet row.
1. Unplug device.
2. Two people to remove from wall/cabinet (remove two, large, top mounting screws and rotate entire microwave down and off the wall mount). Should be some wood spacers between top of device and bottom of cabinet.
3. Remove screws from sheet metal cover.
4. Remove one screw holding blowers in place and rotate out of the way, in order to gain access to 2 of 5 screws that hold the magnetron in place.
5. Unplug magnetron and remove the 5 screws.
6. Drop in new magnetron and re-assemble microwave in reverse order (steps 5-3).
7. Two people restore micro to wall/cabinet. Replace wood spacers, re-install two, large mounting screws (finger-tight). Test device. Secure the two large screws.

Note: also had to replace turntable. Removed top cover using secure driver set. Placed microwave on it's front, using a soft towel. Removed edge screws from bottom plate (leaving 4 screws in center attached to heavy transformer). Separated bottom plate from body of microwave (leaving transformer wires still attached) exposing Synchronous motor. Removed two screws holding motor and electrical plug. Swapped new motor in its place. Re-attached bottom plate with its screws. Placed microwave onto it normal position. Re-attached top cover with its secure screws. Installed new turntable inside.

1. Removed exterior cabinet using vice grips to grab the heads of the screws.

2. Removed old broken latch.

3. Snapped the new latch into place. Be careful spreading the two brackets that receive the latch so that they don't break.

4. Re-install exterior.

Unplugged appliance. Removed external cover's screw's from the microwave. Unplugged 3 internal plugs for wiring harness to the control panel which houses the door latch. Removed old door latch, carefully snapped new door latch in. Reassembled unit in reverse of dis assembly.

Took the cover off, had a lot of screws but easy. Removed the old motor and inserted the new motor. Replace the metal cover and it was ready to go. Can't believe I have waited so long to do this. I was going to replace the microwave but could not find the correct size to fit the cabinet.

Removed micro bottom - 5 screws. One screw on the motor and a clip. Reversed the sequence, turned it on and watched it turn.

Remove 2 Philips Head screws on left side of microwave. Remove 3 Philips Head screws from bottom rear of microwave. Remove 4 security screws from back of microwave (holding the cover to frame). These are the security type tips that are like a Torx bit, but need to be hollow in middle to accommodate pin in center of screw. Then back plate of microwave with heavy transformer still attached slides up and away. The wires aren't long enough to allow it to rest flat on the bench, but weight is low so it's easy to hold it upright while removing the motor unit. Separate connector from motor (simple) Remove motor by unscrewing 1 phillips head screw and rotating counter-clockwise a tiny bit. Remove Motor. Reverse steps to re-assemble. Note that there are a series of tabs at the bottom of the back cover that fit into holes in the baseplate of microwave. It can be a little tricky to line them up with the weight of the transformer, but it's not too bad. Once lined up, it drops in nicely and all the various screw holes line up. The microwave is a bad cooker when the plate doesn't spin. This simple and inexpensive fix saved me from having to buy a whole new oven.

I removed the microwave from its built-in position by removing the faceplace. This was a simple four phillips screw removal. I then removed the microwave and the rear housing. This required the special TORX T20 security star screwdriver. Once the main microwave housing was removed the broken latch was apparent and easily accessible. The longest part of this process was getting the security star driver and ordering the part. It literally took sixty seconds to replace the part. Another three minutes to replace the housing and Another five minutes to put the microwave back in place. This was an easy repair and saved me about $400 in replacement costs.I am very satisfied with the ease of determining the part I needed on the website, the cost of the part, the shipping was timely, and the overall experience by far surpassed my expectations. I am by no means a handy person but the instruction and detail associated with the purchase gave me the confidence and knowledge needed to complete the task.

Although the housing cover of the microwave had the "tamper-proof screws" described by earlier commenters, I easily removed them with pliers rather than a special screwdriver. Like others, I found that one of the two hinge posts on the plastic Door Latch Bracket had broken off. The broken bracket could be removed easily, but I had trouble fitting the blade of the replacement part into position until I loosened one more screw on the receiving latch board to allow extra maneuvering room. Only then did both hinge posts fit into their proper mounts and snap in easily.

Purchaced special security type srewdriver to gain access to interior of microwwave. Latch is press fitted in roller type receiver. No tool required to remove and replce new latch. Reassembled cover and job completed.

Removed the MW from the wall. Took the top screws off the air vent. Then removed the two screws holding on the display. I then moved the display to its side and it revealed the micro switches. I removed the plug in leads from the micro switch one at a time. I did this with all three micro switches only one at a time. I reinstalled everything and plugged it in. No more fans starting when the door is opened.

Initially we started looking to buy a replacement microwave to replace our 13+ year old built-in microwave. It was a real pain finding a replacement to fit the exact dimensions. So I thought I'd try to find an old KitchenAid microwave. However, I was pleasantly surprised when this site came up on my search. Their website allows me to input the problems and then it showed two possible parts that needed to be replaced. I emailed tech support and asked them which part I needed. They responded very quickly and said I needed to replace the magnetron. I watched a couple YouTube videos and then pulled my microwave apart. It was incredibly easy to pull the outer cover off. The magnetron had 5 screws that needed to be removed and one electrical plug. Took me maybe 10 min to complete the entire repair. It was one of the easiest repairs I've done and so thankful for this site They saved me a ton of money from not buying a new microwave and we now have our microwave working again. In hindsight, I wouldn't hesitate. I'd order the Part now and get it fixed.
