Norcold RV refrigerator neil 12-9-16  
My refrigerator every once in a while, flashes, HI/AU, hat does this mean?
Re: norcold RV refrigerator Keith 12-9-16  
Hi Neil, are you sure it's not HI/AC? Since no model number is noted.... AU is the auto setting, I can't see HI/AU unless you have a newer model that has this fault code.

HI/AC is indicating over 132 volts to the fridge from the generator, shore power, or an inverter. If this is not the case, the circuit board should be replaced. I'd have it checked out by a qualified RV tech before doing that though. Good luck
