Possible Causes

Combustion fan running too fast, Fire pot overfilled with ash, Exhaust restriction causing turbulence, Very soft pellets producing extra ash

How to Fix / Troubleshooting

Safety first: Turn off and unplug the grill, and allow it to cool before cleaning ash.

  • Step 1 – Clean fire pot and barrel: Remove grates, drip tray, and heat baffle. Vacuum ash from the fire pot and bottom of the barrel.
  • Step 2 – Check exhaust: Ensure the chimney and exhaust ports are clear and the cap is adjusted correctly.
  • Step 3 – Use better pellets: Switch to a higher‑quality pellet brand that produces less ash.
  • Step 4 – Inspect fan control: If the fan seems excessively strong or runs at full speed constantly, the control board may be overdriving it and could require replacement.
