What OC means on a Dacor refrigerator

The OC error code on a Dacor refrigerator indicates that the FoodSaver thermistor circuit has been detected as open during the FoodSaver diagnostic test. A thermistor is a temperature-sensing resistor whose resistance changes predictably with temperature. When the control system runs its diagnostic routine on the FoodSaver compartment, it measures the thermistor circuit's continuity and resistance. An open circuit means the electrical path is completely broken, producing no readable resistance signal, which the control board interprets as a fault condition.

The FoodSaver module is a specialized compartment designed to maintain precise humidity and temperature conditions for food preservation. The thermistor embedded in this system continuously reports temperature data to the control board. When the circuit reads as open, the board loses all temperature feedback from that zone. This prevents the FoodSaver system from regulating conditions properly, and the OC code is triggered to alert the technician or user that the sensor loop has failed.

The most common causes of an open thermistor circuit are wiring harness failures such as broken wires, corroded terminals, or disconnected connectors at the thermistor itself or at the FoodSaver module. Physical damage from door movement, ice buildup, or vibration can sever a wire or pull a connector loose. If the wiring checks out intact and connections are secure, the thermistor itself has likely failed internally and the FoodSaver module will need replacement.

Common causes of OC

  1. 01

    Disconnected thermistor wiring connector

    Wiring / connection

    The connector linking the FoodSaver thermistor to the wiring harness may have come loose due to vibration or movement. Inspect all connectors along the thermistor circuit for a loose or unplugged connection.

  2. 02

    Broken or damaged wiring in the harness

    Part replacement

    A wire in the thermistor circuit may have fractured internally or at a stress point, creating an open circuit even if the connector appears seated. Carefully trace the harness for pinched, cut, or kinked sections and test continuity with a multimeter.

  3. 03

    Corroded or oxidized terminal connections

    Wiring / connection

    Moisture inside the refrigerator compartment can cause terminal pins to corrode over time, breaking the electrical path. Look for discoloration, pitting, or white residue at the connector terminals.

  4. 04

    Failed FoodSaver thermistor

    Part replacement

    The thermistor itself may have failed internally, resulting in an open circuit that cannot be corrected by reseating connections. If wiring and connectors check out, thermistor failure is the likely cause and the FoodSaver module should be replaced.

  5. 05

    Faulty FoodSaver module

    Part replacement

    If the thermistor and all wiring test good but the OC code persists, the FoodSaver module itself may have an internal fault. Replacement of the module is the recommended corrective action in this scenario.

Frequently asked questions about OC

What does OC mean on a Dacor refrigerator?
The OC code means the FoodSaver thermistor circuit was detected as open during the refrigerator's FoodSaver diagnostic test. An open circuit indicates a complete break in the electrical path of the temperature sensor, so the control board receives no signal from that thermistor. This prevents the FoodSaver compartment from operating correctly until the wiring or module is repaired.
Can I fix the OC error code myself?
A knowledgeable DIYer can start by checking that all wiring connectors along the FoodSaver thermistor circuit are firmly seated and free of corrosion. If a loose connector is found and reseated, the code may clear. However, if the thermistor or wiring harness is physically damaged, or if the FoodSaver module needs replacement, professional repair is recommended.
Is it safe to keep using my Dacor refrigerator with the OC code active?
The main refrigerator and freezer compartments should continue to operate normally while the OC code is active, so food stored outside the FoodSaver section is generally not at immediate risk. However, the FoodSaver compartment cannot maintain proper conditions without a functioning thermistor, so food stored in that zone should be moved until the fault is resolved.
How much does it cost to repair the OC error code on a Dacor refrigerator?
Repair costs vary depending on what component has failed. If only a loose connector needs reseating, costs may be limited to a service call fee, typically in the range of $75 to $150. If the FoodSaver module requires replacement, parts and labor combined can range from $200 to $500 or more depending on the specific model and regional labor rates.
Will resetting the refrigerator clear the OC error code?
Resetting the refrigerator by unplugging it briefly may temporarily clear the displayed code, but the OC fault will return as soon as the FoodSaver diagnostic runs again if the underlying open circuit has not been repaired. A permanent resolution requires identifying and correcting the wiring fault or replacing the FoodSaver module.
