Possible Causes

Restricted airflow from dirty fan or vents, Low pellet feed rate, Wet or low-BTU pellets, Leaking lid gasket or misaligned lid

How to Fix / Troubleshooting

Safety first: Turn OFF and cool the grill before deep cleaning.

Steps:

  • Clean internals: Remove grates, drip tray, and diffuser. Vacuum ash from the fire pot, burn chamber, and exhaust path.
  • Inspect fan and vents: Clean the combustion fan blades and ensure intake and exhaust vents are not blocked.
  • Check pellets: Use high-quality, dry hardwood pellets. Avoid blends with excessive bark or filler.
  • Inspect lid seal: Check the lid for warping and ensure it closes evenly. Replace any worn gaskets if equipped.
