I saw a similar problem description at and was confident to take the challenge to repair it myself. (Thanks to When I opened the microwave cover I found 3 similar switches. 2 of them works the same way and the other in reverse direction. Image diagram provided to buy parts is helpful to identify the switch.
Remove the built-in microwave from the wall and keep it in an open space.
Remove the microwave screws and take the cover out.
Remove the 2 screws(inside) from the plastic panel where switches are snapped in
Gently remove the faulty switch and replace with the new one.
(In my case the topmost secondary door switch was broken)
