Fridge - insufficient cooling on gas

I got my answer. I saw online that some Camcos are adjustable. I got home from work and checked into mine and sure enough, it is adjustable. I adjusted the pressure up to 11" WC with the fridge and 3 range burners going. I'll see how the fridge performs now. I can't tell any difference visually by looking at the flame, but I'll see what happens. Maybe the flame is burning hotter now. If there is more gas pressure, the flame has to be producing more heat I would think, although it might be a minor difference.

Since I have the ability to adjust the pressure, I'm thinking checking the pressure output needs to be an annual part of my inspection process every spring.
