Had 18 pork butts in the smoker friday/saturday and the temperature was all over the place. Had it set for 220 and the air temperature overnight was low 60's. I've used it a few times this year and the temperature would go up/down a few degrees but Friday it was bouncing 15 to 20 degrees above and below the 220 set temp. I'm going to call customer service tomorrow, (which from past experience are AMAZING ) but just wondering if there is something that I may need to replace that's on it's way out or something I may have done when I cleaned it the last time? ( It was really greasy after doing a brisket, then prime rib, chicken and ribs all back to back )
Any help or suggestions is appreciated.
Thank you !
