I have a Kitchen Aid Wall Oven Microwave Combo Model KEMS308SSS05 that is around 2 years old.

Oven works fine

Microwave oven just died with the following symptoms.

-Display works fine and illustrates as if working normally.
-Microwave itself is dormant and silent, no fan, no stirrer/magnatron sound, no light, no turntable.
-video located here Broken Kitchen Aid Microwave - YouTube

Two items to note

-we returned home from a week long trip and the oven had error message on both displays. I hit cancel which reset the error message. The problem is likely associated with this as this is the starting point of the dead microwave
-for many months before and after a self cleaning cycle in the oven, the microwave would have a loud fan noise when operated which research sounded like a bad stirrer.

I love fixing appliances and have no problem digging into this one but before I pull it from the wall I was hoping to get some feedback of likely issues or things to test.

Many thanks....
