I am getting ready to do a Pork Loin for the super bowl and My MasterBuilt wont heat up. It keeps reading EAAF on the Digital Control Panel. I dont have a clue what is wrong with it . Worked fine the last time I used it. Its been snowing here and we have about a foot of snow but the smoker is under a roof outside. Anyone got any ideas on what the problem is and if I could give it a quick fix to save the smoked loin for the super bowl?
