The ARP device may seem pricey, but the protection of the cooling system will dramatically lengthen the life of the cooling unit. If the system gets too hot on a regular basis, corrosion inside the tubing will happen and you ultimately will develop a leak. Besides the protection, our fridge has worked better than ever before, and you will know it's doing its job when you see the power shut off for a short time and then power comes back on, which is the device keeping the fridge cooling unit from overheating.
