Jenn-Air Refrigerator Error Code CC

The CC code stands for Closed Circuit and means the refrigerator detected a short circuit on the ClimateZone temperature thermistor during its CZT self-test. The control board reads near-zero resistance from the thermistor circuit, which falls outside the valid range for any real temperature reading. The fault points to a problem in the thermistor wiring, connector, or the sensor itself.

The CC code specifically affects the ClimateZone compartment's temperature monitoring, which means that section may not maintain its intended temperature range reliably. The main refrigerator and freezer compartments typically continue operating, but you should avoid storing temperature-sensitive items in the ClimateZone drawer until the fault is resolved. Addressing the code promptly prevents potential food safety issues in that compartment.

If the repair requires only a new ClimateZone thermistor, parts and labor typically range from around $100 to $250 depending on your location and the service provider. If the main control board is at fault, the total cost including parts and labor can range from roughly $300 to $600 or more. Getting a diagnostic visit from a certified technician first can help narrow down the cause before committing to a larger repair expense.

A knowledgeable DIYer can perform the initial diagnostics by inspecting the thermistor wiring and connectors for visible damage, pinching, or moisture. If the thermistor itself needs replacement, that is generally a straightforward repair involving disconnecting the old sensor and plugging in a new one. However, if the fault is traced to the main control board, board replacement is more complex and may be better handled by a qualified technician.

Unplugging the refrigerator or cycling the power may temporarily clear the code from the display, but the CC code will return when the control board runs the CZT test mode again if the underlying short circuit is still present. A reset does not repair the faulty wiring, connector, or thermistor, so the root cause must be corrected for the code to stay cleared.
