Maytag Refrigerator Error Code CC

The CC error code means the refrigerator's control system has detected a closed circuit condition, or short, on the CZT temperature thermistor during a CZT test mode. The thermistor is a sensor that monitors temperature in a specific cooling zone. A short causes the resistance reading to drop abnormally low, preventing an accurate temperature measurement and triggering this code.

The CC code indicates the refrigerator cannot reliably read temperatures in the affected CZT zone, which means cooling in that area may not be properly controlled. Running the appliance in this condition risks food spoilage if temperatures are not being maintained correctly. It is advisable to address the fault promptly and verify temperatures with an independent thermometer in the meantime.

Repair costs vary depending on the root cause. If the issue is simply a loose or corroded connector, the fix may cost little to nothing beyond your time. A replacement CZT thermistor typically runs in the range of $20 to $60 for the part. If a control board replacement is needed, parts alone can range from $100 to $300 or more, with additional labor costs if a technician is hired.

Some causes of the CC code are DIY-friendly, particularly inspecting and reseating thermistor wiring connectors or drying out a moisture-affected connector. If the thermistor itself has failed internally, replacing it is a moderately accessible repair for someone comfortable with basic appliance disassembly. However, if the control board is at fault, that repair is more complex and may warrant a professional technician.

A reset may temporarily clear the code from the display, but it will return if the underlying short circuit in the CZT thermistor circuit has not been resolved. The control board runs the CZT test mode and will detect the fault again each time. A permanent fix requires diagnosing and correcting the wiring issue or replacing the failed thermistor.
