A:Answer Greetings!
No, the vent of this Samsung range model does not have a cover that opens and closes manually or automatically. The vent, which is an adiabatic vent, is designed to allow for pressure equalization while minimizing heat loss, regardless of whether the oven is in use or not. This means that the vent remains open at all times, providing a pathway for excess pressure to escape and helping to maintain a controlled cooking environment inside the oven.
