We get an error code on our Norcold refrigerator stating "HI AC" whenever we are plugged into our 50amp shore power at home. This code does not come on when using the generator. I know that the refrigerator code is set to come on when AC is higher than 132V. I measured our shore power at the outlet at 133.8V. Is 1.8V over the normal accepted AC voltage range going to damage our appliances over time? If so, could anything be done to lower the voltage coming from the 50amp outlet? I always use a surge protector.
