Quick Answer

Gas BBQ: low gas, blocked burners, worn igniter, or lid not closed. Gas: check gas bottle level, clean burner ports with a wire brush, replace worn igniters.

Why This Happens

Gas BBQ: low gas, blocked burners, worn igniter, or lid not closed. Charcoal: not enough coals, vents closed, or using old/damp charcoal. Both: windy conditions, cold weather, or dirty grease traps restricting airflow.

How to Fix It

  1. Gas: check gas bottle level, clean burner ports with a wire brush, replace worn igniters
  2. Gas: check the regulator — sometimes it trips and restricts flow. Turn off fully, disconnect, wait 30 seconds, reconnect
  3. Charcoal: use a chimney starter for reliable lighting
  4. Charcoal: open all vents fully, ensure the ash catcher is clear
  5. Both: preheat with the lid down for 10-15 minutes
  6. Both: clean grease traps and ensure airflow isn't blocked
  7. Cold/windy: use a wind break and add extra fuel
