If you experience the flame cutting out with your Ooni 3 Gas Burner, it's important to carefully follow the outlined steps in this article (The flame in my Ooni Gas Burner is cutting out) before proceeding with the following instructions.
Your oven has a built-in safety feature known as an FSD (Flame Supervision Device). This mechanism automatically shuts off the gas supply if the thermocouple fails to register a sufficiently high temperature.
Over time, the FSD bolt connecting to the thermocouple might gradually loosen. This loosening can potentially cause your flames to unexpectedly cut out. Regularly checking and tightening the FSD bolt can help ensure the consistent and safe operation of your oven.
