Samsung Range Error Code C-

The C- code on a Samsung range indicates an oven temperature performance failure. It triggers when the oven does not reach expected temperatures during Bake or Broil mode, or when it fails to reach 150°F (66°C) within 5 minutes at room temperature. The most common cause is a faulty oven temperature sensor or a problem with its wiring harness. A failed heating element can also produce this code.

It is not recommended to use the oven while the C- error is active. The code indicates the oven is not heating properly, which means food may not cook to safe internal temperatures. There is also a risk that an underlying component fault could worsen with continued use. Use the stovetop burners only until the oven issue is diagnosed and repaired.

Disconnecting power briefly may temporarily clear the C- code, but if the underlying fault is still present, the error will return once the oven attempts to heat again. A reset does not repair the component causing the fault. Proper diagnosis and repair of the temperature sensor, wiring harness, heating element, or control board is required for a lasting fix.

A knowledgeable DIYer can perform the initial diagnostic steps. Start by disconnecting power, removing the rear cover, and using a multimeter to measure resistance at the two oven temperature sensor harness connectors. If the sensor reads outside its normal room-temperature resistance range, replacing the sensor is a straightforward repair. If the sensor checks out, further diagnosis of the wiring harness and heating elements is needed, and control board replacement may require a professional technician.

Repair costs depend on which component has failed. An oven temperature sensor is generally an affordable part, with replacement costs typically falling in the range of $20 to $80 for the part itself. If a bake or broil element has failed, parts usually range from $30 to $100. A control board replacement is the most expensive scenario, with parts potentially ranging from $100 to $300 or more. Professional labor costs will add to these estimates.
