Your refrigerator may take up to 8 to 12 hours before it produces usable ice cubes.

The initial batches of ice cubes may have irregular shapes, colours, or other impurities especially if your refrigerator is a plumbed model. You may want to discard the first two or three batches before your appliance starts producing perfect ice cubes.

Your refrigerator needs to stand level and balanced on its feet to function properly. Try rocking the appliance from side to side or back and forth. If it is wobbling too much, your flooring or the appliance's feet may be uneven.

Use a spirit level to check the appliance's balance. If it's off, adjust the feet by reaching under your refrigerator and finding the two front feet. Turn the feet clockwise or counterclockwise, until they are firmly in contact with the floor.

Your refrigerator needs some time to settle before you can start using it. You should let it stand unplugged, in an upright position, for at least 4 hours to allow its compressor oil to settle. 

You can plug your appliance in once 4 hours have passed. Make sure that the thermostat control is set to ON but don’t start loading food right away. Allow your fridge some time to cool down to temperatures safe for food storage, which might take up to 12 hours. 

Ideal refrigerator temperatures 40 °F or below for the fridge and 0 °F for the freezer compartment. Check the temperature inside your appliance with an accurate thermometer. 

Place the thermometer inside a cup of water and put it inside the fridge compartment. To check freezer temperatures, do the same with the thermometer inside alcohol or cooking oil (because water would freeze). You can begin storing food when the desired temperatures are reached. 

Allow 24 hours for the refrigerator to cool down so that it can chill water properly. Also, the water dispenser needs to have the trapped air in the water line removed when it is first connected or every time the water filter is replaced.

Place a large container below the water dispenser and start pressing and releasing the lever for 5-seconds intervals. Repeat until water begins to flow. Once water starts flowing, continue pressing and releasing the dispenser paddle until a total of 4 gallons of water has been dispensed. This will flush the air from the filter and the water dispensing system, ensuring pure and fresh water for drinking.
