We have Paul Unmack and his wife Mao here at our Quartzsite Circle, and they just put on a presentation this afternoon. The ARP device will not void any warranty and their model that controls the additional fans works great, as we have had an ARP device, now called Fridge Defend by ARP, for close to six years, ever since we had our cooling unit replaced the second time, and our fridge is still working great. The sooner you protect your fridge with the ARP device, the sooner you help protect it from damage from excessive heat at the boiler of the cooling unit. This is their web site,
