Possible Causes

Blocked chimney or exhaust, Fire creeping up auger tube due to overfilled firepot, Combustion fan not running, Hopper lid gasket missing or damaged

How to Fix / Troubleshooting

Safety first: Turn the grill off and unplug it. Keep the hopper lid closed if you suspect fire in the auger. Do not add water.

  • Step 1 – Allow cool‑down: Let the grill cool completely before opening the hopper or firepot.
  • Step 2 – Inspect chimney: Check the exhaust stack for obstructions such as foil, nests, or heavy soot. Clean thoroughly.
  • Step 3 – Clean firepot: Remove excess pellets and ash. An overfilled firepot can allow flame to travel up the auger.
  • Step 4 – Verify fan operation: Ensure the combustion fan runs during startup and cooking. Replace if not operating.
  • Step 5 – Replace hopper gasket: If your model uses a gasket on the hopper lid, replace any worn or missing sections to improve sealing.
