Fisher & paykel fridge e521t no power to fridge,not any power coming to fridge

If there's no power to the fridge, then check the breaker / fuse panel - the model number of the fridge is irrelevant if there's no power at the wall socket.

Where I live, fridges must have their own dedicated breaker, with nothing else except a clock on the same branch / circuit.

If there's power to the fridge, (ie unplug fridge, plug in a lamp, lamp works) but not in the fridge, then perhaps the compressor has run to long / hard, and has overheated. A thermal fuse inside the fridge may have tripped. They often reset, once they cool down again.

Did you try an other electrical outlet? Can you test the outlet has any voltage?
does the fridge have an on / off switch? I don't think so, so if nothing works also check the cable and the plug going in the outlet.
