GE Refrigerator Error Code CC: Troubleshooting... | appliancefaults.com

Technical Background:

The CC error code on a GE refrigerator typically indicates a problem with the communication or reading from the refrigerator compartment temperature sensor (thermistor). The MCU (Main Control Unit) constantly monitors the thermistor voltage to maintain proper temperature. An out-of-range voltage or no signal triggers the CC error. Thermistors vary resistance based on temperature, and the MCU interprets this resistance to control cooling cycles.

Symptoms:

The refrigerator compartment is either too warm or too cold. You might also notice ice buildup in the freezer, or the refrigerator not cooling at all. The CC error code is displayed on the refrigerator's control panel.

Possible Causes:

Faulty thermistor in the refrigerator compartment.
Blocked air vents restricting airflow.
Defective main control board (MCU).
Wiring harness issue affecting temperature sensor signals.
Damaged damper motor controlling airflow between freezer and refrigerator.
Excessive frost buildup on the evaporator coils.

Solution:

1

Disconnect power to the refrigerator at the breaker panel.
2

Locate the refrigerator compartment thermistor. Typically located near the top or back of the refrigerator.
3

Using a multimeter, measure the resistance of the thermistor. Compare the reading to the temperature/resistance chart in the service manual. At 70 degrees Fahrenheit, a typical reading might be around 5000 ohms.
4

Inspect air vents for obstructions (food, ice). Clear any blockages.
5

Check the wiring harness connecting the thermistor to the main control board for damage (cuts, frayed wires).
6

If the thermistor and wiring are good, replace the main control board. Ensure the new board is properly programmed for your refrigerator model.
7

Reconnect power and monitor the refrigerator to verify the CC error is resolved.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental re-energization. Some components may contain 120V AC, so use caution when testing live circuits.

Prevention:

Regularly clean the refrigerator's interior to prevent food from blocking air vents. Periodically check the condenser coils (usually located at the back or bottom) and clean them with a vacuum cleaner and brush to improve cooling efficiency. Avoid overfilling the refrigerator, as this can restrict airflow.

Expert Tip:

Many GE refrigerators have a service mode. Accessing this mode allows you to run diagnostic tests on various components, including the thermistors and damper motor. Refer to the service manual for your specific model to learn how to enter service mode. A common sequence involves pressing and holding specific buttons on the control panel simultaneously for several seconds.

Frequently Asked Questions

•Where exactly is the refrigerator thermistor located in my specific GE model?

The exact location varies depending on the specific model number. Consult the service manual or parts diagram for your refrigerator. It's typically located near the top or back wall of the refrigerator compartment, often near the air vents.

•How do I find the correct temperature/resistance chart for my refrigerator's thermistor?

The temperature/resistance chart is usually included in the service manual for your refrigerator model. You can often find the service manual online by searching for your refrigerator's model number followed by 'service manual'. Alternatively, you may be able to find a replacement thermistor kit with the chart included.

•How do I determine if the main control board needs to be replaced?

Replacing the main control board should be considered after ruling out all other potential causes. Verify the thermistor is good, the wiring is intact, and the air vents are clear. If the error persists after addressing these issues, the control board is likely the culprit. Check the voltages going to the board with a multimeter to verify proper power supply to the board before replacement.
