Grill starts but then goes out mid-cook; fire dies and temperature drops to ambient while controller continues running.

Safety first: Turn the grill OFF and allow it to cool before cleaning or relighting.

Step-by-step checks:

• 1. Check hopper level: Ensure the hopper has sufficient pellets and that they are feeding freely into the auger intake.
• 2. Break pellet bridges: Stir pellets in the hopper to eliminate tunnels or bridges that prevent feed.
• 3. Clean firepot: Remove grates and diffuser, vacuum ash and unburned pellets. A clogged firepot can smother the flame.
• 4. Verify fan operation: On startup, confirm that the combustion fan runs with a steady airflow. Clean the fan intake and blades if dirty.
• 5. Restart properly: Follow the Grilla Grills manual for relighting after a flame-out, typically involving clearing the firepot and running a normal ignition cycle.

When to call a technician: If flame-outs occur repeatedly despite clean internals and good pellets, the control board timing or fan output may need professional evaluation.
