Talked to Tony at C.S. yesterday and heres an update. It seems that in the 180* setting, the auger cycles in the on awhile/off awhile mode,until it reaches a certain temp. It then goes into the temp. mode to maintain the temp. If the temp. drops below a certain point (like when you open the door) it switches back to on awhile/off awhile. With me so far? According to him,enough pellets could be dumped into the fire pot to snuff out the fire. This does and has happened,again according to him. I'm my be confused as to the auger modes,running full time to reach temp. vs. on/off. but you see what could happen. Anyway, I consider this just a part of "knowing your cooker" which we all know is just as important as meat selection,cooking temps., etc. and as Fast Freddie pointed out,it's probably some "Voodoo" thing!
