Fridge stopped geting cold on electric

Thanks for all the info. will try the drop light tomorrow see if the plug is bad. also will borrow a Ohm meter to test circuits, checked lower fuses already, all good. Check light never came on ether AC or gas (which doesn't light anyway). I have a surge protector hook up at the shore pole,( think maybe its not getting enough power to the fridge? ) I've used 30 protector since rig was new in 2011.
