First, there are three door operated switches in this model. The monitor sw, the secondary sw (both of these are on the bottom in the same bracket) and the door sensing sw on top. The door sensing and secondary switches are both N.O. and have the same part number (probably why you show just two switches). The monitor sw is N.C. and it was not my problem. The secondary sw was bad on my oven but I had replaced the door sensing sw (which wasn't bad) on a previous order and kept the old one so I used it to make the repair. All three switches can be accessed without removing the oven by removing the discharge louver (remove two flat head screws on top and slide the louver to the left) then carefully remove the control panel (one screw on top and lift out). The switches are held in place by a plastic tongue that fits into the rear mounting hole on the switch. I used a common screw driver with a small tip to gently lift the tongue and slide the switch out with needle nose pliers. The new switch just snaps back in. The switch holder bracket looks like it would be easily broken so be gentle. I don't know what the symptoms would be if either of the other switches were bad so I would recommend buying all three and you would have them if one of the others failed in the future. The information I gave on the switches came from a schematic I found inside the control box. Hope this is helpful.
