Whirlpool Ice Maker Not Harvesting Cubes: Jammed Cube... | appliancefaults.com

Technical Background:

The ice maker's MCU controls the harvest cycle. Voltage is sent to the ice maker motor to rotate the ejector blades. An ice level sensor detects the ice level and signals the MCU to stop ice production. If the ejector is jammed, the motor can stall, and the sensor might not register correctly.

Symptoms:

The homeowner observes that the ice maker is full of ice but is not ejecting the cubes. A large, misshapen mass of ice appears to be blocking the mechanism. No new ice is being produced.

Possible Causes:

Ice cube jam in the ejection mechanism
Foreign object obstructing the ice maker assembly
Faulty ice maker motor or gear assembly
Malfunctioning ice level sensor
Defective ice maker module

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Locate the ice maker assembly inside the freezer compartment. Usually held in place by screws or clips.
3

Visually inspect for any ice jams or foreign objects blocking the ejector arm or cube mold. Use a flashlight for better visibility.
4

Manually rotate the ejector arm to dislodge any stuck cubes. Use a plastic tool if necessary to avoid damage to the mold or ejector blades. Gently pry any stuck cubes.
5

Once cleared, restore power to the refrigerator.
6

Monitor the ice maker for proper harvesting. Allow 24 hours for ice production to stabilize.
7

If the issue persists, further component testing, such as checking the ice maker motor voltage (120V AC) and ice level sensor, may be needed.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. High voltage components are present. Use caution when working near electrical connections. Lock Out/Tag Out (LOTO) procedures should be followed.

Prevention:

Regularly empty the ice bin to prevent ice from clumping together and forming jams. Clean the ice maker assembly periodically with a damp cloth. Ensure proper freezer temperature (0-5 degrees Fahrenheit).

Expert Tip:

Many Whirlpool ice makers have a service mode that can be accessed by pressing and holding the ice maker test button for 3 seconds. This will force a harvest cycle and can help diagnose problems. Note: Repeated use can overheat the ice maker.

Frequently Asked Questions

•How do I test the ice maker motor?

Disconnect power. Use a multimeter to check continuity across the motor terminals. Also, with power applied, carefully check for 120V AC at the motor input using proper safety precautions.

•Where is the ice level sensor located, and how do I test it?

The ice level sensor is usually located on the side of the ice maker assembly or on the ice bin. Use a multimeter to check for continuity or voltage output as per the service manual.

•How often should I clean my ice maker?

Ideally, clean your ice maker every 6 months to prevent mineral buildup and ice jams. Use a mild detergent and warm water.
