LG Ice Maker in refrigerator compartment frosting up
If the ice maker in your refrigerator compartment is frosting up, the most likely cause is warm air leaking in from a bad door gasket — a twisted, torn, or worn seal lets humid air hit cold surfaces and builds frost. Next check the dispenser mechanism: a faulty dispenser solenoid or a bad dispenser door motor can prevent the dispenser door and actuator from moving correctly, and a stuck or damaged dispenser door, a clogged or broken funnel guide, or an actuator pin that doesn’t move freely can leave the compartment exposed to warm air. Inspect the gasket, test the solenoid and motor with a multimeter if you have one, clear any obstructions around the funnel guide, and replace any bent or broken dispenser parts. Addressing these common problems will usually stop frost from forming and keep your ice maker making ice again.

01 - LG Refrigerator Door Gasket
A door gasket should form an airtight seal around the appliance's frame to keep the cold air in and the warm air out. If the door gasket is twisted or torn, gaps can form that will allow warm air in, which can result in frost building up on the ice maker compartment. Inspect the door gasket for any damage and replace with a new one if necessary.

Highly Likely
02 - LG Refrigerator Dispenser Solenoid
The dispenser solenoid opens a door flap to release the ice and then closes the door flap once the dispenser finishes dispensing ice. If the dispenser solenoid is defective, the dispenser door won’t open. To determine if the dispenser door solenoid is defective, use a multimeter to test it for continuity. In addition, check the dispenser actuator pin to ensure that it moves freely. If the dispenser door solenoid does not have continuity, or if the actuator pin does not move freely, replace the dispenser solenoid.
Common
03 - LG Refrigerator Dispenser Door Motor
The dispenser door motor opens and closes the dispenser door to prevent cold air from escaping the refrigerator. If the dispenser door motor is defective, the dispenser door won’t open. As a result, the dispenser will not dispense ice. To determine if the motor is defective, first determine if the motor is getting power. If the motor is getting power, but it won’t run, replace it. You can use a multimeter to test the motor for continuity. If the dispenser door motor does not have continuity, replace it.
Common
04 - LG Refrigerator Dispenser Funnel Guide
The dispenser funnel guide is the component that allows the ice from the ice maker to be properly dispensed. If the guide is obstructed or broken, the ice may not dispense as expected. Inspect the funnel guide or any obstruction or damage and replace if necessary.
Common
05 - LG Refrigerator Dispenser Door
The dispenser door is opened by a motor, solenoid or actuator arm to dispense the ice, but if the door is broken, it may not open properly in order to release the ice. You should inspect the dispenser door for damage to determine if the component should be replaced. You may have to remove the dispenser control panel or frame to access and inspect the dispenser door.
Common
06 - Dispenser door stuck open
If the dispenser door is stuck open, warm air can enter the ice maker compartment causing frost buildup and potentially stopping the ice maker. Remove any items that may be keeping the dispenser door from closing.
