C-10 on a Samsung oven means the temperature sensor failed its own self-test, a check the control board runs to confirm the sensor circuit is reading within a valid range. Unlike the rapid-rise codes in the C-2x family, C-10 usually points more directly at the sensor component or its connection rather than at airflow.
What Causes a Sensor Self-Test Failure
- A temperature sensor probe that has failed internally or shorted
- A loose or corroded connector between the sensor and the wiring harness
- Damaged sensor wiring, sometimes from heat exposure over years of use
- A control board input that has degraded and can no longer read a valid signal, though this is less common than a sensor-side problem
What You Can Check
Cut power at the breaker for a minute and restart the oven, since a one-time glitch can occasionally trip this code without a real hardware problem. If you can safely access the back panel without disturbing gas lines or exposed wiring, a visual check for a loose harness connector near the sensor is reasonable. Avoid running a bake or broil cycle repeatedly while C-10 is active, since the board may not be reading cavity temperature accurately during that time.
When Service Is Needed
If the code returns after a reset, the sensor itself typically needs to be tested with a multimeter and replaced if it’s out of the expected resistance range. This is a common, well-understood repair on Samsung ovens. Our oven repair service covers sensor diagnosis and replacement for Samsung wall ovens and ranges.
