What Does Error C-22 Mean?

The Samsung Oven error code C-22 indicates a malfunction in the internal temperature sensing system. This error typically arises from a defective oven temperature sensor, leading to incorrect temperature readings and failure to heat properly. During operation, you may notice a buzzing sound, and the oven may struggle to complete preheating or baking cycles. Addressing this issue often involves inspecting and potentially replacing the temperature sensor or diagnosing control board malfunctions.

Common Symptoms:

  • Error C-22 appears on the oven display either at startup or during a cooking cycle.
  • Oven fails to complete preheat or bake cycle.
  • Oven temperature may not be correctly read or controlled.

Possible Causes

  • Defective oven temperature sensor (shorted or abnormally low resistance). (high)
  • Wiring fault between the temperature sensor and main control board. (medium)
  • Control board misinterpretation due to a faulty PCB or connector issue. (medium)

How to Fix Error C-22

DIY Fix Power Reset and Basic Check

  1. Turn the oven off and disconnect it from power (unplug or switch off at breaker) for at least 60 seconds.
  2. After reconnecting power, try to restart the oven to see if the code clears (useful if caused by transient electrical glitch).
  3. Ensure oven vents are not obstructed and the oven cavity is cool before further steps.

Technician Only Inspect and Replace Temperature Sensor if Faulty

  1. Disconnect power at the breaker and allow the oven to cool.
  2. Access the oven’s rear/side panel to locate the oven temperature sensor.
  3. Visually inspect the sensor and its wiring for damage (burn marks, melted insulation, pinched wires).
  4. Test the sensor’s resistance with a multimeter; if resistance is below specification or fluctuates, replace the sensor.
  5. Check wiring continuity from the sensor to the main control board and repair or replace any damaged harness.
  6. Reassemble and test the oven; clear stored codes if applicable.

Parts needed: Oven temperature sensor, Wiring harness (if damaged)

Technician Only Control Board Diagnosis/Replacement

  1. If sensor and wiring test within specification, evaluate the main control board’s inputs and connectors for faults.
  2. Inspect for signs of damage or corrosion on the PCB; re‑seat or replace connectors if needed.
  3. Replace main control board only if sensor and wiring checks are confirmed good but C‑22 persists.

Parts needed: Oven main control board

🛑 When to Call a Pro:
  • If after basic power reset the C‑22 error reappears consistently.
  • If you are not comfortable safely accessing internal oven components.
  • If multimeter testing of sensor and wiring is inconclusive or beyond user capability.
