  • cold air in kitchen exhaust

    having finally vented the exhaust fan of our over the stove mounted GE microwave, i am noticing a not insignificant amount of cold air seeping in. the unit exhausts to an outdoor wall cap with a sring loaded flap meant to keep out critters. the microwave has a similar metal flap that is opened by the exhaust air whenever the fan is activated. anyone here know of anything i could insert between the squirrel cage fan and the wall cap to reduce cold air infiltration? thanks.
    there's a solution to every just have to be willing to find it.

    i have the same problem with the rental house i'm in.

    when the wind blows from a certain direction cold air spills in through the range hood.

    i know the louvers inside are working but they can't stop the cold air from coming in.

    i've been forced to stuff a plastic bag around the fan to prevent this.

    just be patient.

    there are alot of people on this forum with good advice.

    sorry i couldn't help you out.

    i just didn't want you to think you were being ignored.

        It is a common problem. and I do not have a real answer,

        make sure the vent closer is not bent and is closing completely, and not have any build up on it keeping it open,
        possibly a better vent hood,

        the other possibility is to form some kind of shield around the vent to block the wind from it so it is not hit straight on,
