My Ooni Koda 12 is making a loud roaring sound.

If your Ooni Koda 12 is making a loud roaring sound, this may mean that your burner has ignited in the wrong spot. This is called 'backlighting'.

To fix this, follow the steps below:

1. Switch your oven off for 5 minutes, then re-light. Make sure to turn your control dial very slowly.
   
   
2. Make sure there's no wind flowing into your oven (position your oven so that wind flows against the back instead of into the front).
   
   
3. Make sure there's enough gas in your tank (low pressure in your gas tank can lead to backlighting).
