    Furnace runs but not blower on automatic
    We have just started using the heat occasionally. The furnace is turning on with the thermostat set, but the blower isn't. If I put the blower to manual it turns on, but not in the auto setting. What do I need to do?

    It's a bad circuit board or fan limit control. If the fan on switch will make the fan run during a call for heat just leave the fan on, on, until you can get it repaired
