John,
Check to ensure the refer is plugged into AC power.
Go outside and remove the lower vent cover for the refer.
Look to the left inside that compartment and locate the single AC outlet. If the refer is not plugged into it, find the cord laying loose there and plug it in. Perhaps it came unplugged.
Also, check all AC breakers in the breaker panels and Test, then Reset all GFCI outlets (kitchen and bathroom).
