Samsung Microwave Error Code C-10

C-10 is a cooking sensor information code indicating that the gas sensor output value has fallen outside the acceptable range, either below 5 or above 250. When this happens, the microwave automatically cancels the cooking cycle and displays C-10. The code points to a problem with the sensor itself, its connector, or the wiring between the sensor and the control board.

The microwave will automatically cancel any sensor-based cooking cycle when C-10 is active, so it will not complete those cooking programs. Manual time-based cooking may still function, but the underlying sensor fault should be repaired before relying on the appliance regularly. Continuing to use the unit without fixing the fault means automatic cooking features will remain unreliable.

If only the connector needs to be reseated, there is no parts cost involved, just time. If the gas sensor needs replacement, parts typically range from around $20 to $60 depending on the model, plus labor if a technician performs the repair. A full technician service call including parts and labor generally falls in the range of $100 to $200, though this can vary by region and service provider.

In some cases, yes. Start by unplugging the microwave and inspecting the sensor connector and wiring harness for loose connections, corrosion, or visible damage. Reseating the connector sometimes clears the fault. If the connector and wiring look fine, the sensor component itself likely needs to be replaced, which is a more involved repair that requires disassembling the microwave cabinet.

Unplugging the microwave and plugging it back in may temporarily clear the display, but the C-10 code will return as soon as a sensor-based cooking cycle is attempted if the underlying hardware fault has not been corrected. A reset does not repair a failed sensor, damaged wiring, or a loose connector.
