The grill ignites but then goes out after 5–15 minutes; the temperature drops and pellets stop burning.

Safety first: Turn the grill off and allow it to cool before cleaning or disassembly.

• Clean fire pot thoroughly: Remove grates and diffuser. Vacuum ash and debris from the fire pot and surrounding area. Ensure air holes are clear.
• Check pellet quality: Replace any questionable pellets with fresh, dry pellets stored in a sealed container.
• Observe auger feed: With the hopper full, run the grill and watch pellet movement. If pellets feed intermittently or not at all, inspect the auger for partial jams or motor issues.
• Verify fan operation: Confirm that the fan runs continuously during the cook. If airflow is weak, clean or replace the fan assembly.
• Avoid frequent lid opening: Opening the lid repeatedly can disrupt combustion and cause flame-outs. Use the lid thermometer or digital display instead of lifting the lid often.
