what make and model fridge. Sounds like a cooling unit issue. Do you have any external fans on the fridge. If so. Are they working.

Check the seals on your doors and, if it's a two-door, check the flap between the doors. Feel the cooling fins to see if they are cold.

How long has it been on? Did you let it cool down before loading it?

Also check the thermistor. It’s located on the fin. It could be defective.For the sake of 20 bucks I would replace it and see if your refrigerator gets cold. A bad thermistor will allow freezer to work and get cold but not frig.

Domestic DM2852. It seems to work on LP but not when plugged into 50amp or running on generator.

Have you verified that the refrigerator is getting 120 volts?

You could have a fuse blown on the control board. One fuse controls the heating elements which are 120 volts zmd are required to get hot when using the electric sude

I check the fuze and it looks good, you would think there would be a breaker somewhere.

I have not, guess I need to figure out where to test, don't look like there is access to any wires inside the camper.

There is a fuse on the control board on the back of the fridge. You need to access it from outdoors on the backside of the fridge. Remove vent and see if you can locate the control board. It’s covered with a black cover. Shut down 12 volt kill switch and 110 Shore power before removing cover to check fuses. Check operating manual first to see if/ what type of fuses are contained on control board.
