Anyone see this? Just curious if anyone used one. Your RV Refrigerator boiler operates at about 350 degrees all the time, but even a brief time off-level, like driving up a hill, can send that temperature sky-rocketing. Events like this produced a lot of thermal stress in the fridge boiler, stress that causes the metal to fatigue and the anti-corrosion chemicals in the coolant to deteriorate leading to fridge failure and perhaps even causing an RV fire. This is the reason for Dometic and Norcold recalls leading to class action suits.
The ARP Control can monitor the boiler temperature and automatically shut down the boiler if temperatures begin to climb out of normal range. Best of all, ARP continues to monitor and re-starts the fridge once it cools down again, so that your food doesn't spoil.
