new glass tray

Make sure to have your model number correct. First tray I purchased I didn't use the model number and just picked what I thought would work (KitchenAid), but didn't. Second attempt I put in the model number and received the correct one. Take out of the box and into the oven, that easy.

Had to remove door. Next pop off the plastic trim around door. Remove spring holding latch place new latch and afix it to the door frame

It was a bit awkward because the microwave is mounted over my stove. I had to twist around and install the bulb and then replace the cover. It was a bit uncomfortable. It took me about 10 minutes to complete.

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.

unscrewed and removed grate. removed old filter and slide new one in.

change light bulbs

Finding the part was the most difficult as this is a very old microwave. I spoke to a really nice lady and we figured out that even though it was not the exact dimensions of my previous film that it would certainly fit since it was just a little bigger that what I had. Once I got it lined up correctly, it was really easy to put on after I removed the backing and took off the old film which wasn't difficult either.

Removed case,
Discharged HV capacitor and removed cooling fan.
Unscrewed ground end of HV diode and unplugged from HV capacitor.
Installed new diode by reversing the order. In my case, the problem was the magnetron was bad, so I replaced it as well.

Took old ones out, threw away and put new ones in easily.

Really easy for a 75-year old female; just spent more time reading the online manual than actually installing the light bulbs to find out where to access the light bulbs.

Piece of cake. One screw to release the dropdown light diffuser. Just remember, the you're screwing the new bulb in from a reverse perspective. Also this site sends the correct part the first time.

Unplug microwave! It's NOT necessary to remove microwave from above stove. Removed two Philips head screws on top front of unit to remove front grille. Removed one screw to remove control panel, letting it hang down. Found inline fuse in cabinet where line cord wires come in. Pulled out blown fuse with thumb and forefinger. Snapped in new fuse, replaced control panel and grille with the three screws. Plugged in the microwave. -Worked great! Good opportunity while grille was off to clean it and replace the charcoal filter inside the cabinet.

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.
