Thanks everyone...I really jumped the gun on this one...the fridge is working...I thought it would at least show some signs of cooling after more than an hour, but I see now it takes way longer. Thanks for all the input..as for the vent..still not working. We have checked the fuses and everything looks good, so still scratching our heads on that one. This is only the second year we have had the trailer, and the first year it was all set when we bought it used, so this is our first year really opening it. Still have lots to learn...
