How Long Should My Fridge Last?

QUESTION: Will the ARP Control make my refrigerator last forever?

ANSWER: No, the ARP is no different from any other preventive mechanism. Failure is just a natural process, prevention is just smart. For example, the human body is known to last longer when diet and exercise are implemented as a preventive measure. But, diet and exercise will not make anyone live forever, no system in nature can be absolutely prevented from failure. Degradation is a natural process. Just as diet and exercise can help you live longer, limiting the boiler temperature of your cooling unit will help your fridge live longer.

Will the ARP Stop All Fires?

QUESTION: Will the ARP Control keep all fires from occurring in my RV?

ANSWER: The ARP only senses excessive boiler temperatures when the control is turned on and has been installed and maintained properly. The ARP control cannot prevent fires when there are defects to the cooling unit or if the cooling unit has been abused before the ARP was installed. Although limiting your boiler temperature is the best preventive measure to prevent a cooling unit boiler caused fire, there are many sources of refrigerator fires. A partial list, but not limited to, would include rodent nests, insect nests, wiring failure, LP gas leaks, and 120VAC failures.
