Product review (1 stars): Annoying cold air blows out front.  Poor fit into existing 30" slot.  Don't buy.
I have only had this range 2 weeks and I hate it and wish I had bought a free-standing one to replace our old slide in range (this would have required cutting our stone backsplash and possibly shaving down adjacent cabinets but would have been much preferable for total cost and for quality of the final product).  Here are my complaints:
 - when the oven is on (either convection or not) IT BLOWS COLD AIR OUT THE FRONT OF THE OVEN.  I don't know if this is normal (I've called the installer to check) but it's awful to stand in front of a cold wind.
 - the oven is designed to stick out from the countertop, so we cannot push it back towards the wall enough.  This is annoying because there is now a gap in the back.
 - the oven door is wider than the 30" space that the oven slides into.  Thus while the oven fit into our 30" space, the adjacent cabinet doors bang on the oven door.  I will need to get a carpenter to come shave down these cabinet doors.
 - the knobs to turn on gas top are sticky and difficult to use
 - as others have said the oven is loud and you cannot turn off the fan.  This isn't a huge problem, but an annoyance.

I would never buy this again and would not recommend it.
