Replaced the microwave door switches. There are 3 of them, one at the top and 2 at the bottom of where the door latches into the main body of the microwave. You have to remove the upper vent guide (it pulls out) to expose the single Philips head screw that holds the right-side panel in place. Once removed, the right-side panel lifts out. I took several digital pictures of all the wire connections on the circuit board so I could unplug them all and get the panel out of the way. The door switches are in a plastic piece that is held in place with 2 Philips head screws. Remove those and pull the wire connectors off of each switch so you can get the entire plastic piece out. The switches are held in place with a plastic post and other molded plastic pieces. Be careful not to break the pieces holding the switches. I actually broke one on the bottom switch so I had to use gorilla glue to hold the new switch in place. The total time would have taken less than 15 minutes to complete.
