What C-20
actually means.
C-20 is Samsung's code for the oven sensor itself. The electric manual lists two versions of the problem, a sensor circuit that opens while the oven is running and one that has shorted, and the gas manual calls it an oven sensor malfunction. Either way the control has no usable reading, so it will not keep baking.

What to do when C-20 shows on the stoveKind of codeTemperature sensor
The thin probe on the back wall of the oven sent the stove a reading it would not trust, or one that kept climbing past the setting. A loose plug behind the stove or a probe knocked against the racks is ruled out before the sensor or the board is replaced. If the oven keeps getting hotter with the controls turned off, switch the stove off at its breaker first.

Before you book,
in this order.
Each step comes from Samsung's own guidance for C-20 on its stoves. Follow it to the end: the last card says whether this is a visit.
Press OFF/CLEAR, then start the bake again and watch whether the code returns.
If it does, switch the stove's breaker off, wait at least 30 seconds and switch it back on.
Use the burners or elements on top if they still work, but leave the oven off until it is checked.
When C-20 survives the breaker reset, book a visit so the sensor and its harness can be measured.

What not to do
C-20 does not mean your oven actually got too hot. Samsung gives the overheated oven its own number, C-21, so the two call for different checks.

Still showing C-20?
Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
