Have you checked all your fuses and reset any circuit breakers? Are you plugged into a known good ac power source? Is there anything else that does not work including all your AC outlets, lights, etc. Once you can isolate that the only thing that does not work is truly the fridge, then you can start thinking about something internal to the fridge itself. If so, the first thing I would do is pull the panel off the back side of the fridge and while using a volt meter, check that the power inlet has power. Do you have the schematic of the fridge to work with?
