On most fridges you can,tip it backwards and you will probably find the bottom hinge is secured with 2 or 3 screws when you loosen them the whole door will drop down,the top hinge is usually just a pin in a hole.Use a sharp blade to take the centre plate out of the handle and unscrew it.There will be small plugs covering the holes for the other side of the door hinge(remove with sharp blade)put them in the old holes,just unpick and swap over all the bits.It should fit first time.
