Grill overshoots set temperature by 50°F or more and runs excessively hot

Safety first: Monitor the grill closely when it is running hotter than expected to avoid grease fires.

• Step 1 – Clean RTD probe: Wipe the temperature probe inside the cook chamber with a damp cloth to remove grease buildup that can insulate it and cause slow response.
• Step 2 – Verify setpoint: Confirm the controller is set to the desired temperature and not in a high-heat mode.
• Step 3 – Observe auger behavior: Watch the auger during operation. It should cycle on and off. If it runs continuously, the auger relay on the control board may be stuck, requiring board replacement.
• Step 4 – Check for air leaks: Inspect the lid gasket and body seams. Excess air leaks can increase combustion and raise temperature. Replace worn gaskets.
• Step 5 – Controller calibration: Some models allow temperature calibration. Compare with a reliable grill thermometer and adjust per the manual if available.
