Nordic Cooling Units is the premier remanufacturer of RV refrigeration cooling units. If your RV refrigerator isn't cooling and smells of ammonia, the cooling unit has failed and needs to be replaced. The number one reason cooling units fail is because they rust out and start leaking ammonia. Also, if your unit has been run off-level, a blockage can form inside the cooling unit preventing proper circulation of the charge solution. Repairing your refrigerator with a remanufactured Nordic Cooling Unit is significantly less Expensive than replacing the entire RV refrigerator. Our units are completely remanufactured to the highest standards by experienced professionals.
