What C-21
actually means.
Samsung uses C-21 when the temperature inside the oven climbs abnormally high. The control shuts heating down to protect the stove, the cabinets around it and the food.

What to do when C-21 shows on the stoveKind of codeOven heating
The oven part of the stove was set to bake or broil and did not warm the way the controls expected, or took far too long to get there. On an electric stove a bake or broil element that has burned through is the everyday reason; on a gas stove the oven igniter and the valve it opens are looked at first. The wiring and the relay on the board are checked before the board itself is blamed.

The oven part of a stove that stays cold, heats slowly or bakes too hot or too cool, fixed at the bake and broil elements, the oven igniter, the gas valve or the temperature sensor.

Recipes take much longer or much less time than they should, cakes burn on the outside and stay raw inside, or an oven thermometer disagrees with the display by more than a little.

Before you book,
in this order.
Each step comes from Samsung's own guidance for C-21 on its stoves. Follow it to the end: the last card says whether this is a visit.
Press OFF/CLEAR and leave the oven door closed while it cools on its own.
Check that nothing is covering the vent and that no foil lines the oven floor or racks.
Once the oven is cool, switch the breaker off for at least 30 seconds and back on.
Should C-21 reappear the next time you bake, retire the oven for now and book a visit.

What not to do
C-21 is not a report of a broken sensor wire. On Samsung stoves the sensor itself is C-20, while C-21 means the reading was real and too high.
