    Auger continually feeds. The auger turns ever so slightly all the time and then pluses to a stronger turn every time the control energizes. Swapped out the mother board and adjusted the feed trim. Thinking that the daughter board controller is to blame here, any thoughts?

    Sounds like a leaky triac or driver to me. Is the triac on the daughter board?

    Daughter board. Just had a customer with a very similar problem which for that is generally always either the daughter board or the control board and you already tested the control board.
