Dometic refrigerator gas problem

I got a new (to me) Camper. Outback 28 foot bumper pull. First weekend out and loved it!
I found out that the gas did not light up. I found a dirt dauber shield at the site the gas should shoot into the burner. I cleaned that out and brushed the burner as well as poked da wire up to it.
Than I realized the gas was off at that point also. I turned the little knob and the starter was working with a good crisp snap. Only it would not ignite at the burner, it lights up before the burner, right where the gas comes out of the nozzle. There is about an inch space between the gas orifice and the beginning of the burner. I also sprayed compressed air and coil cleaner into the burner. It looks clean.
Any ideas would be appreciated to assist me.
Thanks'
Glenn

Did you remove and clean the BURNER TUBE (the thing that the gas should shoot into with the slits in the top)?

I cleaned it with a wire, air pressure and a coil cleaner. I don't believe anything is in it. The area looks clean. I did remove the orifice that the gas comes out of. It is clean too.
Thanks,

You might want to have a tech check it out so you don’t have an accidental fire. Would be will worth it. He or she can then check your voltage and igniter. John

The orifice and burner tube are made together. If you poked a wire into the orifice you destroyed it! You can't even blow high-pressure air into it without damage. Don't ask me how I know!

Thank you all for the advice. Know what I did. I removed the burner, looked inside and it looked OK from how I could see. I poked my screw driver into it and poked some more crusty mud out, not much at all but a little. I found a brush pipe type cleaner and brushed it out. Some more crumbs came out.
Replaced it all and wham, works great! Just amazing that just a little crumbs can cause that.
Know I also know that the refrigerator is a 3 way and all 3 works!

Propane System pressure is only 0.39psi and does not take much to disrupt the flow....single spider web will do it

Air is 'pulled' in via that open space between orifice and burner tube
Proper gas flow is critical to get the correct air/fuel mixture. Disrupt that and no ignition

Routine cleaning will keep them working
Fridge, Water heater, furnace, stove etc

Simple..........

Got cha, I will take a look at the water heater and system furnace too, although they work fine!
