Thanks for the replys folks, I have another question, the microwave we are currently using is built into a cabinet above the refrigerator, basically its in a large plywood box with a face frame and there is a hole cut for the microwave to be used. There is plenty of room inside the box, 3-4 inches on each side, 6-8 inches above to the ceiling, and I have a vent cut at the top of the face frame for heat from the fridge and micro to escape. Will I run into problems with the convection oven combo with a set up like this? Jim
