How to Fix / Troubleshooting

Safety first: Turn off and cool the grill before tightening hardware.

  • 1. Level the grill:
    • Ensure all legs or casters are firmly on the ground.
    • Adjust position to eliminate rocking.
  • 2. Tighten hardware:
    • Use appropriate wrenches/screwdrivers to tighten bolts on the hopper, barrel, legs, and shelves.
  • 3. Check internal parts:
    • Verify the drip pan and diffuser are seated properly and not loose.
  • 4. Inspect fan:
    • If vibration coincides with fan operation, inspect the fan blades for damage and replace the combustion fan if bent or imbalanced.
