Universal Ice Maker in refrigerator compartment frosting up

If the ice maker in your refrigerator compartment is frosting up, the most likely cause is air leaking around the door gasket so warm, moist air gets in and condenses on the ice maker. After that, check the dispenser hardware: a bad dispenser solenoid or a failed dispenser door motor can leave the dispenser stuck closed or stuck open, which either prevents ice from dispensing or lets warm air in and creates frost. A clogged or broken funnel guide or a damaged dispenser door can also block ice flow and contribute to icing. Start by inspecting the door gasket for tears or gaps, then see whether the dispenser door opens and closes freely; use a multimeter to test the solenoid or motor for continuity if you’re comfortable with electrical checks. Clearing obstructions or replacing the faulty solenoid, motor, funnel guide, or gasket usually fixes a refrigerator ice maker not working or an ice dispenser not working problem.

01 - Universal 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.

02 - Universal 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.

03 - Universal 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.

04 - Universal 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.

05 - Universal 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.

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.
