Recently replaced the main board, I have the bottom controls set at 6 4 1. When I'm running the heater on setting 1, it runs great,  maybe a little too great,  but if I change the heat setting to 2 or 3 , it's as if the augur slows down,  the fire will almost die out before it gets more pellets and then catch back up.... any ideas of what may be happening 🤔??
