Dometic RM2551 fridge won't operate on propane

I took a gun cleaning brush and cleaned out the tube. I went all the way past the holes. There was no debris. My next task is to check the pressure. Both stove units burn bright blue with plenty of flame. So, I believe the problem would have to be after the split to the stove.

Also,as a footnote, the water heater works very well. Only 20-30 minutes after turning on that we have nice, hot water.
