i started an overnight cook for a couple butts. At 225, this should be a 12+ cook. But I can’t get me PG500 to hold at 225. What am I doing wrong. I even dropped the set temp to 175 just to see what would happen. It was between 260-270. My LHT and HHT we’re both set to 25. Not sure what I’m doing wrong here. Any suggestions?
