What to do if my Ooni Burner will not ignite?

  Amanda EvansAug 18, 2025
  If your Ooni gas burner isn't igniting, here's what to check: 1. Make sure the chimney cap is off, and the ceiling and chimney vents are open, with the door open as well. 2. Ensure your gas bottle isn't empty, as even low gas can affect performance. 3. Inspect the hose for cracks or leaks. 4. Try lighting the burner more slowly, as turning the dial too quickly can prevent ignition. 5. Verify the regulator is correctly attached to the gas bottle and the hose is firmly connected to the burner, using appropriately sized wrenches. 6. Adjust the sparker tip so it's 2-3 mm from the front of the burner cap.

  If the FSD on your Ooni burner isn't working right, soot buildup on the FSD probe may be the cause. Turn off the gas and burner, let it cool, then gently clean the probe and burner holes with a damp cloth. Make sure everything is fully dry before relighting.

  If your Ooni's FSD (Flame Safety Device) isn't functioning correctly, it might be due to soot buildup on the FSD probe. To resolve this, switch off the gas burner and gas supply, wait for the burner to cool down, then gently clean the probe and burner holes with a damp cloth. Allow the burner to fully dry before relighting.
