What C-30
actually means.
Samsung puts a small temperature sensor on the main control board. C-30 means that sensor opened or shorted, C-31 means the board temperature rose abnormally high, and the gas manual adds C-22 for the same board sensor check. The oven stops working until the board is back in range.

What to do when C-30 shows on the stoveKind of codeControl board and power
The main board failed its own start-up check, lost contact with the display, or saw the supply voltage sag too low, often after a storm, a power outage or a spill that ran down behind the panel. The breaker, the cord and the outlet are ruled out before a board is replaced. A stove that sparks, smells of hot wiring or keeps heating while this code shows is switched off at the breaker first.
Usually leads toControl board and display repair
Stoves with a blank or flashing display, touch keys that do not answer, codes that keep returning or a stove that will not turn on, traced to the board, the keypad or the power to them.
Shows up asStove Display Blank or Flashing
The clock and display on the stove have gone dark, or they flash the time, a word or a string of characters and ignore the keys you press.

Before you book,
in this order.
Each step comes from Samsung's own guidance for C-30 on its stoves. Follow it to the end: the last card says whether this is a visit.
Press OFF/CLEAR and let the stove cool, especially after a long bake or self-clean.
Make sure the back of the stove is not pushed against something that blocks air around it.
Switch the breaker off for at least 30 seconds and turn it back on.
If C-30 or C-31 returns, book a visit; Samsung's manual sends C-31 straight to service.
Still there?
It usually turns into control board and display repair. Book with the code and the model number.
What not to do
These codes are not about the oven's own temperature sensor. That one is C-20; C-30 and C-31 concern the board inside the control panel.
