Dometic RM47 Fridge - Propane Issue

Hello all! It's been a long time...

Recently, in my 1976 Argosy, The dometic RM47 refrigerator no longer works on propane. Previously, it worked perfectly on both 110 v and propane. Now when I try to light it, It will ignite but the flame will only go to an orange yellow color and not the typical blue. Then it will eventually just burn out. I'm assuming there's some kind of oxygen to fuel ratio issue... Does anyone have any fixes for this? Something I should be looking for particularly?

I have the front end torn out so I am able to remove the refrigerator if needed...

Thanks for any help!

General idea as I've never seen your model. Pics can help too.

The burner where the flames are, remove that burner tube and look for foreign objects, bugs, webs anything. Clean that burner tube out and try again.

I tried cleaning out the burner but apparently the igniter snapped. And manually lighting, it it still doesn't light correctly. The flames are coming out earlier in the tube than where it's supposed to...

Does anyone know where I can get a new burner assembly for this model?

I will add some photos...

Sorry, no clue where to search for parts. Do you have this service manual? https://rvrefrigeratorrepair.com/wp-...ce-EarlyRM.pdf

On page 31 it has an illustrated parts list, page 33 and 55 show the burner. If flame is not coming out where it should I'd look for burner tube obstructions or obstructions in the chimney.

Broken parts, oops.

Pics might bring other ideas.

That manual is very helpful. Know that I know what I need, anyone have any idea of where to locate it?

Looks like I need a thermocouple and an ignitor. Possibly a new burner jet and burner pipe.
