How to tighten the FSD bolt for Ooni Koda 16Updated 7 months ago
### If you experience the flame cutting out with your Ooni Koda 16, it's
important to carefully follow the outlined steps in this article ([The flame
in my Ooni Koda 16 is cutting out](https://support.ooni.com/en_us/the-flame-
in-my-ooni-koda-16-is-cutting-out.-what-should-i-do-rko5aAOzj)) 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.
**Note: **If you encounter difficulty with the screws, apply a gentle over-
tightening until you hear a distinctive '_click_.' This will effectively
disengage the screw, making it easier to be removed.
### ** ⚠ BEFORE YOU BEGIN:**
