Our Viking microwave VMOS200  just suddenly quit.  I was just using it and it wouldn't restart.  The light came on and the timer would count down but carousel wouldn't rotate and it wouldn't start.   Watched a YouTube video and found the exact situation and the repair was the micro door switch.   There are four inside this model and 3 are normally open and one normally closed.  Using an ohmmeter to check them to see which was faulty.  All functioned normally except one which was intermittent and wouldn't work in the normally open position but would work with a slight pressure on the door open button.   I replace the switch and it worked perfect.
