What to Check First
- Unplug your refrigerator before connecting or handling the water supply line.
- After installation, check the connections at your refrigerator and water shutoff valve for leaks to prevent water damage.
- If you use copper tubing, install it indoors where the temperature stays above 0°C (32°F) to prevent freezing and bursting.
- Connect the automatic ice maker to a cold water supply with a pressure between 20 and 120 psi.
- You may need a separate adapter depending on your home’s plumbing.
- If you need to use your refrigerator before connecting the water line, turn off the automatic ice maker.
- To use the automatic ice maker and water dispenser, you must connect your LG refrigerator to your home’s cold water supply. For a safe installation, first unplug your refrigerator and connect a compatible water supply line. Once connected, check all connections for leaks, and make sure to flush the water line before using the water or ice.
- The automatic ice maker and water dispenser on your LG refrigerator use water directly from your home’s plumbing. To use these features, connect the refrigerator to a cold water supply with a water supply line. If the water line is not connected, your refrigerator cannot dispense water or make ice.
- Connect a standard 1/4-inch water supply line to your home's cold water shutoff valve. If the line does not fit the valve, use a compatible adapter.
- Place the end of the water supply line in a large bowl or container. Open the water shutoff valve. Let the water flow through the line until it runs clear to remove dust and debris. Close the water shutoff valve. This removes dust and debris from inside the line before you connect it to the refrigerator.
Why This Can Happen
Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
