The only thing that low AC voltage will affect on one of these gas/electric RV fridges would be the heating elements. They are the only thing connected to 120 volts AC. The best combination of protective devices for these rigs is an EMS system, and an ARP device to directly protect your fridge. I have a hardwired Progressive EMS in our rig and have an ARP device wired to the fridge. If the voltage gets too low or there is another problem with the incoming AC, the unit will shut down power until it gets back to a good range. The ARP device shuts the fridge cooling unit off if the temperature of the cooling unit exceeds a safe level, which prevents crystal buildup inside the system and also keeps the tubing from developing cracks due to high temps which helps prevent leaks. The money spent on these two devices is well worth the protection, just like buying insurance, except you only pay one time.
