    Furnace blower won't shut off
    The furnace blower won't shut off, no heat just cold air... The only way to shut it off was to turn off the central air breaker. What could cause this?

    With most furnaces if a limit switch opens up the gas is shut off and the blower runs all the time until the limit is reset.
