Controller displays 'OPEN LID' or a similar message, and the temperature will not rise to the setpoint.

Safety first: Avoid leaning over the cook chamber when igniting; hot air and smoke can escape rapidly.

• Step 1 – Close lid: Ensure the grill lid is fully closed during startup and normal operation.
• Step 2 – Wait for recovery: After closing the lid, allow several minutes for the controller to stabilize the temperature and clear the 'OPEN LID' status.
• Step 3 – Check lid switch (if present): Some models use a magnetic or mechanical lid switch. Inspect the switch and magnet alignment. Adjust or replace the switch if it does not change state when the lid is opened or closed.
• Step 4 – Inspect RTD probe: A loose or damaged RTD can cause false rapid temperature drops. Verify the probe is firmly mounted and the wiring is intact.
