do you have both shorepower cords pugged in for 120 use?
Is it turned on? Way back in the top right side there is a knob the you would turn clockwise to turn it on and is also is to set the temp.
You should hear it running. The freezer part should frost alittle.
When you disconnect the shorepower it automatically switches over to 12V is that connected?
I know mine is cold with in the hour so if that is not happening a professional might be needed.
I dont have one in my boat but have had similar in caravans in the past, should get cold in an hour max as stated above
