    Intertherm furnace
    My 8 year old Intertherm forced air furnace won't fire. Igniter is good red led is blinking twice says it's a pressure switch is open. Anything I can do myself?

    Try tapping on the pressure switch while observing the status light. If operation is restored, pressure switch may be failing.
