Hi! My name is ***** ***** I can assist you with this. I may need some additional information from you first in order to give a complete answer.

That is most often a sign that the available voltage is too low for the fridge to operate the unit properly. It should be load tested to be sure that it is viable. Only use that when the battery(s) are being charged up from another source like the vehicle alternator or solar panels. One battery with no other input can run down quickly. The light is warning you of this problem. Hope this proves helpful here. Please get back to me if you need more as all follow ups are included in our fee. No time limit.

Can I get an Auto Electrician to load test this unit. I will try it on the main battery to see if I get the error message if not then the fult may be with the Aux battery feed ?

Yes. I would have the battery(s) load tested to be sure they are viable and then if so, give them a full charge and try it again. If that error code still persists then you have an internal issue on the 12 VDC side. That tends to be a trouble source in these.
