Do you mean it doesn't work on gas or electric or both?
Is the 'fridge fitted in a unit with cutlery drawer, microwave etc? if it is you may find that it is should be plugged into a socket behind the cutlery drawer ( Assuming that the layout is similar to our 540UK). If not it may still be possible to check behind the 'fridge in another cupboard. Have you checked all the electrical breakers and fuses?
If it is the gas side that is not working have you checked that the correct gas cock is turned on?( Might sound obvious but plenty of people do it.), If it is and it will not ignite it could still be a fuse etc and if not the igniter may be U/S.
