It vents the stovetop odors and steam.
Sorry, there was a problem. Please try again later.The SMH9187ST has a powerful 400 cfm (cubic foot per minute) vent fan to help remove odors from the stovetop. This exhaust fan can be set up to filter outside, through the top or back of the unit, or it can recirculate filtered air back into the room through the concealed vent in the top front of the microwave. The microwave itself has an internal fan that vents through the front. Thanks for your interest in Samsung! Ms. Samsung
