convection

Most oven doors will have a slight look of being open at the top but are usually touching the seal all the way around. When the oven goes into self clean the hook pulls the door tight against the seal and compresses it.

A simple way to test the door seal is what we call the dollar bill test. Take a dollar, close the oven door on it and you should fee a slight resistance when pulling out the bill. Do this test about every 6 inches around the top of the door.

I tried the dollar bill and there was no resistance to speak of. That said, I roasted a chicken in convection roast mode last night, and it cooked beautifully in the time I expected it to take.

I read elsewhere that the hinges on these may have a known defect that causes them to fail.
