If the water inlet valve is defective, the icemaker is likely to develop problems.The electro-mechanical valve maintains the coil, which prevents the passage of water into the ice maker. The LG refrigerator's icemaker develops problems when the water pressure in the house is too low. The water inlet valve is designed to operate at a minimum of 20 psi of water pressure. When the house supply water pressure is low, the water inlet valve cannot supply water to the ice maker.
Defects in the door switch also cause problems with the ice maker. When the door is opened, it turns off the dispenser and ice maker and then turns on the light. When it fails, the ice maker cannot be turned on and off. The LG refrigerator's ice maker is designed to operate when the freezer temperature is between zero and 5 degrees Fahrenheit. When the freezer temperature rises above 10 degrees Fahrenheit, the ice maker develops problems.Learn more about Refrigerators & Freezers
