Hi,
It wont work if the fridge is more than 10 degrees out of level. If the fridge has been out of level it may be airlocked so take the fridge out and turn it upside down and rotate slowly back to vertical and set it on level area. leave for a few days and try again. Look for leaks and smell of ammonia as this the refrigerant. Some refridgerant engineers can repair and replenish ammonia.
