The water supply must be turned off before checking the water inlet valve. The valve controls water flow. If it doesn't shut off completely, water keeps dripping into the icemaker fill tube and freezes. Certain valves also have a screen, which can become clogged with dirt. The valve requires 20 pounds per square inch of water pressure to operate, so it doesn't work if the house has low water pressure.

All water used by the icemaker passes through the water filter. Over time, the water filter can become clogged, which reduces water flow. A clogged water filter should be replaced, and as of 2015, LG recommends changing the water filter every three to six months.

Icemakers work best when the temperature is between 0 and 5 degrees Fahrenheit. The freezer temperature is lowered using the thermostat. If the temperature doesn't go low enough, it could be due to an issue with the condenser coil, the condenser fan or the evaporator coil.
