Dometic Fridge Gas Flame Lights and Then Goes Out

Hoping someone with more experience can help with this Dometic Fridge Issue.

We purchased a used 2018 Keystone Hideout RV and the sellers mentioned that they could not keep the Dometic Fridge running on gas. So being the handy people we are, we looked and saw the ignitor needed to be replaced due to some damaged insulation on the wire. However, replacing the ignitor apparently wasn't the only issue.

The flame ignites at the end of the tube for a few seconds and is blue. Then the flame goes out at the end of the pipe and the gas ignites at the air gap which is probably what damaged the previous ignitor wire.

So I'm thinking it is either the gas valve or the control board but would like to get someone else's expert thoughts who maybe have had this exact issue.

Thanks for your help.

I would clean the burner tube and replace the orifice,You can’t clean the orifice.

Have set the gap on the igniter? It’s also the flame sensor.
