Error codeC3
ApplianceCooktop
What C3 is
A sensor error: that is how Samsung’s Canadian cooktop listing describes C3. It shares an entry with C0, C1 and C2, so the same instructions cover all four. The listing links the code to no specific model or series.
Working through it
Turn the cooktop off with the Power button and then on again.
When C3 comes back, remove power by unplugging the cooktop or using the circuit breaker, wait 30 seconds, and start it up.

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.
