Possible Causes
Incorrect P-setting too high, Weak or non-functioning fan, Ash-clogged firepot, Control board feeding pellets continuously
How to Fix / Troubleshooting
Safety first: Turn the grill OFF, unplug it, and allow it to cool. Do not restart until excess pellets are removed.
Step-by-step checks:
- 1. Remove excess pellets: Vacuum or scoop unburned pellets from the firepot and surrounding area.
- 2. Clean firepot: Ensure all air holes are clear and ash is removed.
- 3. Verify fan operation: Confirm the combustion fan runs during operation. Replace if not functioning.
- 4. Adjust P-setting: Reduce the P-setting to lower pellet feed rate, especially at low temperatures.
When to call a technician: If pellets continue to overfeed despite proper settings and a good fan, the control board may be malfunctioning.
