We have come across two issues while getting to know our new to us 2011 Pinnacle. First, the Half Time microwave/convection oven will run for 20 seconds or so then stop and the "service" message appears on the control panel. Second: there are switches right inside the outside door. They control kitchen, living room, outside door and outside front lights. The single controls what? the Fantastic fan? We can't get our Fantastic Fan to turn on. Ideas?
