Norcold Refrigerator problem

I'm in a park on power, 30amp in a travel trailer. I opened the door to the unit and the inside light goes out. I shut the door and the green power light flashes twice over and over. I looked at a guide and it says power or fan problem. I have no idea where the fan is or if I even have one. I never heard it run. I will call the repair service in the morning and for now I switched over to gas.
