    Frunace Blows Cold Air
    Hi I have an American Standard Freedom 78 Furnace in the attic. It comes on then goes off when temp is reached but sometime in the night there's no heat just blows cold air. If I switch it back on in the morning it works but then it does the same thing especially when it's 3am in the morning.

    What can I look for. It has Emerson Switch 50A50 White-Rodgers.

    The model number is ADD080C945B0

    Flame Roll out Replacement is WG09X033

    Hope this is enough info.
