Antennae doesn't work and fridge coded after one day of use. 2017 Avalanche 365mb.

[Sue from WI]

Hi....we are at a permanent campsite with our new 2017 avalanche 365mb and can't get the tv to work. It won't pick up any channels. We think the antennae isn't hooked up way up by antennae somewhere. Also, our fridge dies after one day!! The error code stated that it was not user fixable. Any ideas or did this happen to anyone else.? I am sick about it.
