bd is a control board issue. You could try killing the power to the unit, flip circuit breaker, and then turn it back on and see if the error appears again. If error comes back, the control board is the likely culprit.
That's board display on face. I've changed everything else and as you know parts are expensive. Have $500 in it already.
