Possible Causes

Fire creeping up auger due to overfilled fire pot, Combustion fan not running or running backward, Auger tube packed with pellets, Poor exhaust flow from blocked chimney

How to Fix / Troubleshooting

Safety first: Turn OFF and unplug the grill immediately. Keep the hopper lid closed to limit oxygen.

  • Allow to cool: Wait until all smoke subsides and the grill is cool.
  • Inspect fire pot: Remove grates and diffuser, then clear excess pellets and ash from the fire pot.
  • Check chimney and exhaust: Clean any blockage from the chimney and exhaust path.
  • Verify combustion fan: Ensure the fan runs correctly during startup and cook. Replace if not operating.
  • Prevent overfilling: Do not manually add large amounts of pellets directly into the fire pot.
