Lidmh, Howdy;
To add to what Festus2 said.
If you find that you DO have an exterior vent SOME not all have some small plastic tabs that twist across the edges. As I was told "to keep it from flapping". Should you discover a vent check to ensure that the tabs aren't holding it closedwhen you want to cook.
