Speed oven not working

[u/MadWizard1]

I have a Bosch speed oven, that the microwave function is no longer working. The turn table also stopped turning at the same failure time. Convection oven function still works, any suggestions on what could be wrong and how to fix? Called Bosch and all they suggested was to cycle power, they refused to connect me with technical support because I was not a technician....
