How to Fix / Troubleshooting

Safety first: In case of a grease fire, keep the lid closed, unplug the grill, and use a Class B fire extinguisher if necessary. Never use water.

  • 1. After fire is out and grill is cool:
    • Remove grates and drip pan.
    • Scrape and clean all grease from the drip pan, barrel bottom, and grease channel.
  • 2. Inspect drip pan:
    • Check for warping that allows direct flame exposure.
    • Replace the drip pan/heat diffuser if badly warped or burned through.
  • 3. Adjust cooking method:
    • For very fatty meats, cook at lower temperatures or use drip pans to catch fat.
    • Avoid leaving the grill unattended at high heat.
