Dometic Refrigerator Not Cooling Properly

I will try cleaning it from the bottom. I am afraid to remove the top vent cover right because the weather looks like it may rain soon. I have improved the airflow across the coils by streamlining the air flow across the coils and cleaning up the cut thru the roof.
The wife just told me there wasnt any hot water. Got to check that out now.

Thanks for the advice.
