I ordered all three door switches, not knowing which one or one's were bad, but I didn't want to take it apart and have to replace more than one or order the wrong one. After removing the top vent panel (two screws) and having the door open, it exposes a screw on the top of the control panel which hold the control panel in place. After removing this screw, the control panel lifts off the frame. I found it is best to remove the control panel & plugs on the backside to access the switches. Also on the left side by the switches are two screws which hold the frame for the switches. I removed them to remove the frame holding the switches. A You-tube video said to twist the switches to remove them from the frame, DO NOT DO THIS! You will crack the frame because the back portion of two of the switches are held in place with plastic pins which are part of the frame and you will break them off. I very carefully unlocked them from the frame and lifted them out of the frame. The new switches snapped into the frame easily. Replaced the screws to remount the switch frame, connected all the plugs on the switches and control panel. Put the control panel back in place and the top vent. Re-plugged the microwave into the electrical outlet and closed the door. Worked perfectly. After checking the switches, I found that the bottom switch was bad. Now I have two replacement switches. Saved a costly service call. Took about 45 minutes, Received the replacement parts in 2 days.
