AdminRV refrigerators are a big investment and one of the most important appliances in your coach. There are a lot of different options on the market, but many owners choose to go with norcold cooling units. They’re built for the demands of off-road travel and use gas or propane (a norcold fridge automatically switches between fuel sources) as their primary energy source. This makes them quieter than residential refrigerators and less likely to be damaged by road vibration.
The JC Refrigeration unit is a freon cooling unit that replaces the original ammonia based cooling unit on a Norcold 1200 or 1210. The jc refrigeration unit fits into the existing mounting space and uses the same electronics to control it. This makes the conversion to a freon system substantially cheaper than replacing your fridge with a residential refrigerator and avoids the cost of modifying cabinetry in your coach.
During the cooling unit installation process great care is needed to seal the evaporator foam pack pocket. The instructions provided by some manufacturers include applying a tube of thermal mastic around the pocket on the rear of the refrigerator. This is not the proper procedure as thermal mastic is a conductor and does not provide an insulator.
If the evaporator foam pack is not sealed properly, air will be able to get into the evaporator coils and cause a fire. The foam will also deteriorate and leak ammonia into the refrigerator. If you notice yellow residue behind your refrigerator and a strong ammonia smell it is most likely due to a bad seal. norcold cooling units
