Refrigerator help needed.

[ttikalsky]

The refrigerator is not cooling when operating on gas. It works fine
when hooked up to electricity. I pulled the burner out and cleaned
it, reinstalled. I also removed the vent cover on the roof to verify
there was no blockage. I also brushed the fins while the roof cover
was off. I have the wind shield off and the flame is all blue and
looks to be burning the full length of the flame tube. The
refrigerator is a Dometic RM1300. How long should it take to begin
cooling? Are there other things to check? There is also a fan behind
the refrigerator and when I turn the fan on at the galley panel should
the fan be spinning or is thermostatically controlled?
