Symptom
Displayed temperature is significantly different from actual grate temperature.
Temperature Calibration Error
Symptom
Flare-ups or grease fires occur in the cook chamber during use.
Grease Fire / Excessive Grease Accumulation
Symptom
Grease is dripping from the bottom of the grill or running down the legs during cooks.
Grease Management System Blockage or Misalignment
Symptom
