Samsung Range Error Code C2

The C2 code on a Samsung range signals an IGBT sensor fault on the inverter module assembly. The control board monitors a temperature sensor via an analog-to-digital converter: a reading above 239 indicates an open sensor circuit, while a reading below 10 indicates a short. The range disables the affected cooking zone to protect the inverter electronics until the fault is resolved.

The range disables the affected induction zone when the C2 fault is active, so continued use of that burner is not possible in most cases. You should not attempt to bypass or ignore the fault, as the IGBT and inverter components carry significant voltage. Stop using the affected zone and arrange for diagnosis before resuming cooking on it.

Repair costs vary depending on the root cause. Wiring inspections and connector reseating may only involve a service call fee, typically in the range of $75 to $150. Replacing the IGBT sensor or the inverter module PCB will add parts costs, which can range from $100 to $350 or more for the board depending on the specific model. Getting a diagnostic estimate before authorizing parts replacement is recommended.

Some C2 errors are caused by loose or misrouted wiring harness connectors at the inverter module, which a knowledgeable DIYer can inspect and reseat after unplugging the appliance. If the sensor itself has failed or the inverter PCB is defective, those repairs involve working with high-voltage power electronics and are best handled by a qualified technician. Always disconnect power at the breaker before opening the appliance.

A power reset by turning off the circuit breaker for a few minutes may temporarily clear the code if it was caused by a transient condition, such as a brief period of very cold ambient temperature. However, if the underlying cause is a failed sensor, damaged wiring, or a defective inverter PCB, the C2 code will return as soon as the range is powered back on and the system runs its diagnostic checks.
