    Central Heat clicks on and off constantly
    I have a Gibson Electric Central Air & Heat unit, the cold air is fine, but when I turn it to heat it won't stay on for more than a minute or so. It will click off and then on... off and then on and so on. It doesn't matter what the thermostat is set on. Any ideas on what could be the cause of this?
    Thanks so much.

    Only thing under G3B is a variable speed conversion

    It could be a bad heat sequencer or relay. Check the back side of the blower access door for your exact wiring diagram.
