Can you open your cabinet doors completely without banging into the oven door? That would be my best guess as to why the clearance specification for the doors. Also, can you try to contact Frigidaire to find out details of why their instructions specify 1" minimum?

Thanks Prickly--I can open the drawers, but it is close. I was just on hold for 45 minutes with frigidaire before getting disconnected.

I don't know if this is universal, but open those doors/drawers while you run the oven cleaning cycle. We saw side vents on the unit before it was re-installed and it stuck in the back of my mind as a puzzle.

My different brand slide-in oven primarily vents out the top and a little from under the controls in the front UNTIL I run the cleaning cycle, then it vents out the side too. I noticed the interior of the cabinet and some of the drawer glides got hot during cleaning and that the side of the drawer fronts right at the edge got hot too.

There is such a thing as a heat shield. Some cabinet companies sell them to protect thermofoil doors from excessive heat. It might work for you.

Thanks bmorepanic--My thermofoil doors did get damaged from the heat from my oven--aw well as our toaster oven. I am not sure why the drawers would be more of a problem than filler--but I had them move the cabinets over and put filler in by the range.
My old Jenn-Air had some sort of heat shield tape along the top--I think I will look for something that will protect the sides of the cabinets.
