Did you tilt it over and carry it,if so you should have left it in position switched off until it settles,empty it of food switch it off and let it stand for at least an hour then try it.There is a part of the motor that contains oil,if you tip the fridge over the oil spills out(you wont see it)you have to leave the fridge unplugged until the oil drains back to where it belongs,if you buy a new fridge you have to do the same,leave it to settle before switching the motor on.
