Most likely your battery has become discharged because your Converter (battery charger) has stopped charging it. This could be because the circuit breaker which provides 120v power to the converter has tripped, or because the Converter has died.

Another possibility is that the in-line fuse, normally found within a foot or two of the battery, has blown. It normally looks something like this:

and may be resettable (look for a button on it).

(If you don't have a voltmeter/multimeter yet, now is a good time to buy one.)

Sounds like maybe your converter is not working (that would be taking 110V "shore power" and converting to the 12 volt DC your fridge controls and lights need) or a dead battery.

I assume you are plugged in to 110V if your outlets work. Also what make/model is your rv?

I reading from your description that the camper is plugged into 120V shorepower. It sounds like you don't have any 12V DC power was would come from the camper's converter and battery...the fridge requires 12V power for it's circuit board.

Check the voltage across the battery posts with the cables disconnected...a fully charged battery should be about 12.7 V. Also check the voltage across the battery terminals while on should read about 13.5 V...if not, the convertor to kaput.
