Thanks for the reply and yes the hood is closed. I spoke with Bill at Cookshack. He recommended raising the LHT to 30. The main issue is once i get up to temp it falls off and never recovers the temp. Raising the LHT didn’t seem to help. I let it run for an hour and it steadily dropped temp.
I’m trying your suggestion now. Set to 550 with LHT at 30 and HHT at 150. It gets up to about 360 then drops off to about 335. And continues this cycle. Auger is running 100% but isn’t dropping many pellets. I let it run for about an hour and it never topped 360 degrees.
