First understand that your fridge has two operating modes:
1. LP Gas and 12V DC(for electronics).
2. 120V AC (shore power) and 12V DC(for electronics).
So assuming you're plugged into shore power and have a charged house battery it should run on electric. If not check for both sources of power at the fuse panel and breaker panel, and behind the fridge itself.
