Startup seems to go great. Element heats up, blower comes on, pellets fall out and everything works good in smoke mode and at low temps. Once the startup is finished the blower goes off. The issue comes in when I try to go up to the higher temps 300-500. Is the blower supposed to come on at this point? Because mine just starts moving pellets and moving them to the point that it smothers the flame and overfill the pot. Its brand new it happened once during burn-off and again on my first cook.
