KitchenAid Ice Maker in refrigerator compartment frosting up
If your KitchenAid ice maker inside the refrigerator compartment is frosting up, start by assuming warm air is getting in. The most likely cause is a bad door gasket — a torn, twisted, or flattened seal lets humid air in and creates frost. Next check the dispenser door and its controls: a faulty dispenser solenoid or a bad dispenser door motor can leave the dispenser stuck or slow to close, which lets cold air escape and moisture condense on the ice maker. Inspect the funnel guide and the dispenser door itself for obstructions or broken parts that can prevent a proper seal, and make sure the dispenser door is not physically stuck open. You can use a multimeter to test solenoid and motor continuity and check that the actuator pin moves freely. These problems can also lead to an ice maker not making ice if frost or a stuck door interferes with operation. Enter your model number on RepairClinic.com to see the exact replacement gaskets, solenoids, motors, and dispenser parts that fit your refrigerator.
01 - KitchenAid 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 - KitchenAid 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 - KitchenAid 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 - KitchenAid 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 - KitchenAid 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.
