Samsung Range Error Code C-

Oven overheating error

Samsung codesSamsung range codes

Oven overheating error - temperature does not reach expected levels in Bake mode or Broil mode, or oven fails to reach 150°F (66°C) within 5 minutes in a room temperature condition.

First step from the service manual

Disconnect power, open the rear cover, disconnect the two harness connectors to the oven temperature sensor and measure resistance at room temperature. If there are any problems, replace oven temperature sensor.

What C- means on a Samsung range

The C- error code on a Samsung range indicates an oven overheating or temperature performance fault. Despite the name suggesting overheating, this code actually triggers when the oven fails to reach expected temperature levels during Bake or Broil mode, or when the cavity cannot reach 150°F (66°C) within 5 minutes under normal room temperature conditions. The control board monitors temperature rise rate and compares it against expected parameters, and when the oven falls short of those benchmarks, C- is thrown to alert the user and halt operation.

The oven temperature sensor (also called the oven sensor probe or RTD sensor) is the primary component involved. This sensor feeds real-time resistance-based temperature data to the control board. At room temperature, a properly functioning oven temperature sensor should read within a specific resistance range. If the sensor reads out of range, reads open, or reads short due to a damaged probe or compromised wiring harness, the control board receives inaccurate temperature data and cannot confirm that the oven is heating correctly.

Additional causes beyond the sensor include wiring harness faults between the sensor and the control board, a failed bake or broil element that is not generating sufficient heat, or a defective control board that is misreading sensor signals. Diagnosing this code begins with disconnecting power, removing the rear cover, unplugging the two harness connectors at the oven temperature sensor, and measuring the sensor resistance with a multimeter at room temperature. Abnormal resistance readings confirm the sensor needs replacement.

Common causes of C-

  1. 01

    Faulty oven temperature sensor

    Part replacement

    The oven temperature sensor provides resistance-based readings to the control board. A failed or drifted sensor will report incorrect temperatures, causing the board to log a C- fault. Disconnect power, remove the rear cover, unplug the two sensor harness connectors, and measure resistance with a multimeter at room temperature to confirm.

  2. 02

    Damaged sensor wiring harness

    Part replacement

    The two harness connectors that run from the oven temperature sensor to the control board can suffer heat damage, corrosion, or breaks over time. Inspect the connectors and wire runs for visible burns, melted insulation, or loose pins after disconnecting power.

  3. 03

    Failed bake or broil heating element

    Part replacement

    If the bake or broil element is burned out or has an open circuit, the oven cannot generate enough heat to reach the 150°F threshold within 5 minutes, triggering the C- code. Visually inspect both elements for cracks, blistering, or visible break points.

  4. 04

    Defective oven control board

    Part replacement

    If the temperature sensor and wiring harness both check out within spec, the control board itself may be misreading sensor signals or failing to properly command the heating elements. Control board faults are typically diagnosed after ruling out all other components.

Frequently asked questions about C-

What does C- mean on a Samsung range?
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.
Can I fix the C- error on my Samsung range myself?
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.
Is it safe to use my Samsung range while the C- error is active?
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.
How much does it cost to repair a Samsung range C- error?
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.
Will resetting my Samsung range clear the C- error code?
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.
