Is my burner not connected to LP? Pic provided

[Macca]

I’m trying to troubleshoot my dometic fridge. Power comes on the control panel but nothing gets cold. Doesn’t cool on 12v or 120v. Multimeter shows correct power at all points on lower board. When I switch it to gas, I can here the igniter clicking but never ignites the gas.
According to the pics provided, it looks like there is a big gap in the gas line before it enters the arm to the igniter. Is there a piece missing here?

If it has not been used for awhile, you have to bleed the lines. I turn on the propane burners until they light and then turn on other things until they light. My HW heater is in the back end so it lights last. I do not think you are missing a piece. How long are you waiting for it to get cold? It takes some time. Works best to cool it down with ice in some form.

That the fuel-air mixer. There is supposed to be a gap.
Newer models might have a perforated tube, but it's still open to the air for mixing.

Thanks for the replies. Okay. I have bled the lines through the stove burner but not while trying to start the fridge burner. I will try that.
