    Flame cycling!
    I have a Temstar NUGK100DH08 gas HVAC. The unit lights then flame dies down, re-ignights and continues this. Temperature set at 72*. Flame doesn't appear to be rolling out. Exhaust motor is running O.K. and no vacume leak.

    Does anyone know what's wrong. Thks Mike!

    Try cleaning the flame sensor if so equipped.
