I agree with you and not saying it wasn't my fault. My point was to advise a new member who was asking about the maintaining the grill. I could run the grill without deep cleaning for a long time, as long as there is no greeze on the bottom.
BTW, the second incident of the greeze fire happened when I was cooking the pork shoulder at 225F , then wrapped it in the foil and raised the temp to 300F. It took a long time to heat up, and, I guess the flames were extinguished and it accumulated a lot of pellets into the pot. It didn't give the error messages, but the temp was too low (135F) before it started to rise. When it stared to rise, it went crazy hot and overshoot the temp way far. I had to remove the meat, just before the greeze cough on fire.
