Repairing Nor Cold Cooling Units
RVers and campers use Nor cold cooling units in their refrigerators and freezers because of their quiet operation, ease of operation and reliability. The Norcold company has been making these types of gas absorption fridges since 1959 and it is easy to see why they are so popular with weekend warriors and full timers alike.
However, like all things mechanical there are things that can go wrong. One of the most common issues with Norcold cooling units is when they start to cool but then shut off before reaching a low temperature. This can be due to a variety of reasons ranging from a thermistor to a control board and so on.
One way to help resolve this issue is by adding a new thermostatic switch in the proper location. This will allow the fans that pull heat out of the freezer and fridge to start running far sooner in the refrigeration cycle than they do with the original thermostatic switch location.
The best way to make sure your new thermostatic switch is properly located is to have it installed by a professional. They can install it in the proper place, re-use the existing fans and give you peace of mind that the problem is fixed for good.
The Fridge Defend by ARP is an automatic temperature monitoring device that can protect your Dometic or Norcold fridge from cooling unit failure and overheating problems. It is a simple plug in accessory that can be added to your refrigerator that monitors the boiler for overheating conditions. When the fridge overheats the ARP control will turn off the heater that powers the absorption refrigeration process and restart your fridge when cooler ambient temperatures are detected.
