I have a PH35 pellet stove for about 9 years now . It’s been great until now . The problem is a low orange fire , lots of soot and won’t get to temp . Flashes 2x green then goes solid . I have cleaned everything!! Even the pipes outside . I’ve put 2 new ambient probes in ,new exhaust probe , new snap disc , new igniter. Even put a new control board in . Didn’t work so I returned it . Put a new vacuum switch in . That didn’t work . Fires up great after 5 minutes the flame goes down and dark orange . I’ve adjusted the air flow . Now I’m just lost . Dial knob ? Auger not feeding enough ? Any advice will be appreciated . Thanks
