How to Fix / Troubleshooting
Safety first: Operate the grill outdoors in a well-ventilated area only.
- 1. Check pellets:
- Discard any pellets that are swollen or crumble easily.
- 2. Clean fire pot:
- Vacuum ash and ensure air holes are open.
- Do not manually overfill the fire pot with pellets.
- 3. Inspect exhaust:
- Check the chimney cap and exhaust path for grease or soot buildup.
- Clean with a non-flammable degreaser and brush.
- 4. Verify fan speed:
- Listen for strong airflow from the combustion fan.
- If airflow is weak, clean the fan blades and intake; replace the combustion fan if needed.
