On the covered Samsung range or oven, C-22, C-23 means a secondary temperature-sensor circuit is invalid on applicable models. First, record which cavity or mode was active. Then: arrange model-specific sensor service. Note whether the problem appears in both cavities or in only one before you call for service.

0 of 4 completedWhat to do first
ReversibleRecord which cavity or mode was active.
Correct only the documented fault domain
ReversibleArrange model-specific sensor service.
Turn the range off at the breaker
ReversibleSwitch the breaker off for a minute and back on. A temporary temperature reading glitch clears, and this costs nothing.
Have the temperature sensor tested
ReversibleService information for Samsung oven temperature sensors gives about 1,080 ohms at room temperature, with a reading far above or below that marking an open or shorted sensor. A technician measures this with the sensor unplugged.

Common questions about “Samsung range or oven code C-22, C-23”
What does C-22, C-23 mean on a Samsung range or oven?+
A secondary temperature-sensor circuit is invalid on applicable models.
Can I replace the Samsung oven temperature sensor myself?+
It is a common owner repair once the power is off, but the wiring harness is delicate and the reading should be checked with a meter first.
Can I keep using my Samsung oven with a C22 or C23 code?+
The oven has stopped because it cannot trust its temperature reading. Cooking should wait until the cause is found.
Is the C22 code the sensor or the control board?+
Most often the sensor, because it is cheaper and far more likely to fail; the control board is the conclusion when a normal-reading sensor still shows the code.
