I am confused about the reference to the fridge working as the fridge does not work on a battery. We are missing some information but I do not know what it is.
The fridge needs a 12v battery to operate. As the caravan should still be under warranty, I suggest that it is taken back to the dealer unless it was purchased privately.
Do you have an owner's manual? Hopefully you have checked all the fuses. Looking from the left to right the 2nd and 3rd fuses are for the fridge and battery. Above that the first bank of double switch is for the fridge.
Go to the control panel and press the switch at the top and in the middle. This indicates the voltage supplied by the battery however is just a test.
I am looking at the wiring diagram in the owner's manual, but it is not the easiest one to understand, however none of the cigarette sockets seem to on the diagram. Maybe get in a mobile technician to sort out the 12v electrics if the caravan was bought privately.
BTW is the battery charger switched on?
