if the fridge is on electric or gas or indeed 12volt and the outside vent is getting hot ,then im sorry but fridge is totally u/s,these fridges(caravan or motorhome )cannot be regassed,and only a replacement fridge will sort it,we have been mending fridges for over 20yrs,repairing and selling and servicing
