Thanks for the prompt and helpful replies. It's actually not been that hot in our area (Springfield, OR). The fridge and freezer were working fine 10 days ago and then this problem just cropped up on our current outing with no significant change in weather.
When we're prepping for a trip, I usually pre-cool the refer for a day before we load in the food. I turn the unit on using AC power, and then the next morning both the fridge and freezer compartments are cold. This time, the freezer compartment was cold...but not the fridge.
I will check the temps and see what's up. The very first thing I checked was the fuse and it was fine.
