Grill temperature is much lower than display reading (food undercooked)

Safety first: Use heat‑resistant gloves when placing thermometers in a hot grill.

• Step 1 – Verify with external thermometer: Place a reliable oven thermometer or probe at grate level away from direct flame. Compare to the Monument display.
• Step 2 – Clean and inspect RTD: Clean the RTD probe and ensure it is not bent toward the firepot or a hot spot.
• Step 3 – Adjust cooking technique: If the display is consistently high, cook to internal meat temperature using a food probe rather than relying solely on chamber reading.
• Step 4 – Replace RTD or controller: If the discrepancy is large and consistent, replace the RTD probe. If the issue persists, replace the main control board.
