GE Profile Ice Maker: Bin Full Sensor Not Stopping... | appliancefaults.com

Technical Background:

The GE Profile ice maker uses a bin full sensor to detect the ice level. The sensor sends a signal to the main control unit (MCU) on the control board. The MCU uses this signal to stop the ice-making cycle. The sensor typically uses a 5V DC signal. If the MCU doesn't receive the correct signal due to a faulty sensor, wiring, or internal control board issue, the ice maker will continue to produce ice.

Symptoms:

The ice maker continues to produce ice even when the ice bin is completely full, resulting in ice overflowing and potentially damaging the freezer compartment.

Possible Causes:

Faulty bin full sensor
Wiring harness issue between sensor and control board
Icemaker control board malfunction
Ice blockage interfering with sensor arm movement
Incorrect ice maker system/leveling
Software glitch in the ice maker's MCU

Solution:

1

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

Locate the ice maker bin full sensor. It is usually a plastic arm or light sensor located near the top of the ice bin.
3

Inspect the sensor arm for any ice buildup or obstructions. Remove any obstructions.
4

Use a multimeter to test the continuity of the sensor. The sensor should show continuity when the bin is full and no continuity when empty. Refer to the service manual for the correct resistance value if available.
5

Check the wiring harness connections between the sensor and the main control board. Look for loose connections, corrosion, or damaged wires. Repair or replace as needed.
6

If the sensor and wiring are good, replace the ice maker control board. This is often the cause if the sensor signal isn't being processed correctly.
7

Reconnect power and monitor ice maker operation to verify the repair.

Safety Warning:

Disconnect power to the refrigerator before performing any repairs. Use Lock-Out/Tag-Out (LOTO) procedures to ensure the refrigerator remains de-energized. Some components may carry 120V AC – exercise caution.

Prevention:

Regularly empty the ice bin and inspect the sensor arm for any ice buildup. Ensure the refrigerator is level to prevent ice from interfering with the sensor. Clean the ice maker components with a damp cloth every 6 months.

Expert Tip:

Many GE refrigerators have a diagnostic mode accessible through the control panel. Entering this mode allows you to test the ice maker sensor directly and view error codes that may not be displayed normally. Refer to the service manual for your specific model for instructions on entering diagnostic mode.

Frequently Asked Questions

•What is the typical lifespan of an ice maker bin full sensor?

The lifespan of an ice maker bin full sensor varies, but typically lasts between 5-7 years. Factors such as humidity, usage, and voltage spikes can shorten its lifespan.

•Where can I find the service manual for my GE Profile refrigerator model?

You can typically find the service manual online by searching for your specific model number followed by 'service manual'. GE's website or third-party appliance repair sites often host these documents.

•What is the voltage I should expect to measure at the sensor connector?

Typically, you should expect to measure around 5V DC at the sensor connector when the sensor is activated (bin full) and close to 0V DC when it's not activated (bin not full). Always consult the service manual for precise values.
