GE Café Refrigerator Ice Maker Not Dumping Cubes: Timing... | appliancefaults.com

Technical Background:

The icemaker operates based on a programmed sequence controlled by the main control unit (MCU). The MCU sends a 120V AC signal to the icemaker motor, initiating the ejection cycle. A thermostat monitors the ice temperature. When the ice reaches the appropriate temperature (around 15-20°F), the thermostat signals the MCU to start the ejection cycle.

Symptoms:

The GE Café refrigerator's ice maker is producing ice, but the cubes are not being ejected from the tray. The homeowner reports hearing a grinding noise or no noise at all from the icemaker during the ejection cycle.

Possible Causes:

Icemaker module gear misalignment.
Faulty icemaker motor.
Ice buildup preventing ejection.
Defective icemaker water valve.
Frozen or blocked fill tube.
Icemaker thermostat malfunction.

Solution:

1

Unplug the refrigerator or turn off the breaker at the breaker panel.
2

Remove the icemaker cover (usually held in place by screws, use a 1/4-inch nut driver).
3

Inspect the icemaker gears for visible damage or misalignment. Manually rotate the gears to observe the ejection cycle.
4

Check for ice buildup within the icemaker tray and around the ejector arm. Use a hair dryer to gently melt any excess ice.
5

Disconnect the wiring harness from the icemaker module. Using a multimeter, check for 120V AC at the icemaker water valve during the fill cycle.
6

If the gears are misaligned, attempt to realign them. Some models have a reset button, while others require manual adjustment. Refer to the service manual.
7

If the icemaker motor is suspected, it can be tested for continuity. If there is no continuity, the motor is defective and the icemaker module should be replaced.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use appropriate lockout/tagout (LOTO) procedures. The icemaker operates on 120V AC, which can cause serious injury or death.

Prevention:

Regularly clean the icemaker and surrounding area. Replace the refrigerator's water filter every 6 months. Avoid overfilling the ice bin.

Expert Tip:

Many GE refrigerators have a service mode. To enter service mode on some Café models, simultaneously press and hold the 'Freezer Temperature UP' and 'Refrigerator Temperature DOWN' buttons for 3 seconds. This allows you to manually cycle the icemaker to observe its operation.

Frequently Asked Questions

•How do I access the service manual for my specific GE Café model?

The service manual can often be found online by searching for your model number followed by 'service manual'. You can also contact GE directly or a local appliance parts supplier.

•What is the correct gear alignment for my GE Café ice maker?

The specific gear alignment varies by model. Refer to the service manual for diagrams and instructions. Generally, the gears should mesh smoothly without binding, and the ejector arm should move freely through its full range of motion.

•How do I test the icemaker thermostat?

The icemaker thermostat can be tested for continuity using a multimeter. At the appropriate temperature (around 15-20°F), the thermostat should show continuity. If it does not, the thermostat is likely defective.
