Thanks for sharing your experience. Did you do anything special in terms of ducting from the back of the oven to the external vent? That's really my biggest question - how air tight of a seal between the two is achievable and how.
I didn't do any ducting. The exhaust fan I added moved plenty of air from the room through the area behind the microwave outside through the vent. I also added a grill above the microwave to get air from the room.
When it was first installed, the temp behind mine got up to 200 degrees F after 45 minutes in convection mode.The fan and vent kept it way down to around 120 degrees or so as I recall.
