Whirlpool Refrigerator Ice Maker Ejector Arm Jammed:... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) signals the ice maker module to initiate an ice harvest cycle. The module then activates the ejector motor, which rotates the ejector arm, pushing the ice cubes out of the mold. Voltage paths from the MCU to the ice maker module and motor must be intact for proper operation. The thermistor must also be within spec.

Symptoms:

The homeowner notices the ice maker stops producing ice, or produces only partial ice cubes. They observe the ejector arm is stuck, often with a half-formed cube jammed in the ice mold.

Possible Causes:

Ice buildup around the ejector arm.
Damaged or worn ejector motor.
Faulty ice maker module.
Water supply issues causing inconsistent ice cube formation.
Debris or foreign objects obstructing the ejector arm's movement.
Warped or cracked ice mold.

Solution:

1

Disconnect power to the refrigerator at the breaker panel. Confirm 0V AC at the refrigerator outlet using a multimeter.
2

Remove the ice maker cover using a 1/4-inch nut driver.
3

Inspect the ejector arm and ice mold for ice buildup. Use a hair dryer on low heat to carefully melt any ice obstructions.
4

Manually cycle the ice maker ejector arm to check for smooth movement. If it's still jammed, proceed to the next step.
5

Disconnect the wiring harness from the ice maker module. Using a multimeter, test the ejector motor for continuity. A lack of continuity indicates a faulty motor.
6

If the motor tests good, replace the ice maker module. Ensure the new module is compatible with your Whirlpool refrigerator model.
7

Reassemble the ice maker, restore power to the refrigerator, and allow 24 hours for ice production to resume. Monitor for proper ice cube formation and ejection.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization. High voltage is present in the control circuits. Use caution when testing electrical components.

Prevention:

Replace the refrigerator's water filter every 6 months. Periodically inspect the ice maker for ice buildup and clear any obstructions. Ensure the freezer temperature is set between 0-5 degrees Fahrenheit.

Expert Tip:

Many Whirlpool refrigerators have a service mode that allows you to manually initiate an ice harvest cycle for testing purposes. Consult the service manual for your specific model to access this feature. It often involves pressing a specific sequence of buttons on the control panel.

Frequently Asked Questions

•How do I test the water inlet valve to ensure it's supplying enough water to the ice maker?

Disconnect the water supply line from the inlet valve. Place the end of the line in a bucket. Activate the ice maker harvest cycle through service mode. The valve should deliver a steady stream of water. A weak or intermittent flow indicates a faulty inlet valve or low water pressure. Minimum pressure should be 20 PSI.

•What is the correct resistance reading for the thermistor in the ice maker?

The thermistor's resistance varies with temperature. Consult the service manual for your specific Whirlpool model. Generally, at 77 degrees Fahrenheit, the resistance should be around 5k ohms. Use a multimeter to measure the resistance and compare it to the specifications in the manual. Out-of-range readings indicate a faulty thermistor.

•If the ice maker is constantly overfilling, what could be the cause?

The most likely cause is a faulty water inlet valve that's not shutting off completely. Even after the ice maker is full, the valve continues to leak water into the mold. Replacing the water inlet valve is usually the solution. Also, verify the ice level sensor is working.
