Dacor Refrigerator Error Code CC

The CC error code on a Dacor refrigerator indicates that the FoodSaver thermistor circuit has detected a short condition during the FoodSaver diagnostic test. The FoodSaver compartment is a specialized preservation zone within the refrigerator that relies on precise temperature monitoring via a dedicated thermistor. When the control board runs its diagnostic routine and detects an abnormally low resistance reading from the thermistor circuit, it interprets this as a short and triggers the CC code. A properly functioning thermistor will present a predictable resistance value that changes with temperature; a shorted circuit collapses that resistance to near zero, making accurate temperature control impossible.

The thermistor itself is a negative temperature coefficient (NTC) sensor, meaning its resistance decreases as temperature rises. A short circuit in this context means the resistance has dropped outside the acceptable operating range, typically caused by a wiring fault or a failed thermistor component rather than actual temperature conditions. The control board flags this immediately during the diagnostic cycle to prevent the FoodSaver zone from operating in an uncontrolled state.

Diagnosis should begin at the thermistor wiring harness. Inspect the connector pins and wiring for signs of pinching, chafing, moisture intrusion, or corrosion that could be creating an unintended low-resistance path to ground. If the wiring checks out intact and properly seated, the thermistor itself or the FoodSaver module may be internally shorted and will require replacement. Resistance testing across the thermistor leads with a multimeter will confirm whether the sensor or the wiring is the source of the fault.
