Error codeC3
ApplianceCooktop
Quick answer
C3 is a sensor error that Samsung lists with C0, C1 and C2. Restart the cooktop, then remove power for 30 seconds if the code stays.
Model compatibility: Samsung reuses codes across series and model years, so C3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
C3 is a sensor error, listed together with C0, C1 and C2.
C3 on a Samsung cooktop display means a sensor error. Samsung’s support information for cooktops sold in Canada lists it in one group with C0, C1 and C2, and all four share the same instructions. The listing does not tie the code to a particular model or series.
What Samsung says to do
Press the Power button to turn the cooktop off, then switch it back on.
If C3 returns, cut power to the cooktop, either by unplugging it or by using the circuit breaker. Wait 30 seconds and restart it.
If the code is still there, request service.
Other codes in the sensor group
The same group includes C2, a problem with the PBA sensor; C1, where the temperature is sensed higher than specified; and C0, a problem with the burner temperature sensor.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
