Lid thermometer reading does not match controller temperature or grate temperature.

Safety first: Use heat-resistant gloves when handling hot components.

• Use reference thermometer: Place a digital probe at grate level and compare readings to both the lid thermometer and controller.
• Understand differences: Recognize that lid thermometers often read cooler or hotter than grate level due to placement.
• Replace if faulty: If the lid thermometer is wildly inaccurate (e.g., stuck), replace it with a compatible unit.
