What to do when 3C20 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 Won't Turn On
Nothing happens anywhere on the stove: no burner heats, the oven stays cold, the clock and lights are dark, or the display lights up but nothing will start.

Before you book,
in this order.
Each step comes from Wolf's own guidance for 3C20 on its stoves. Follow it to the end: the last card says whether this is a visit.
Turn off the burners and the oven.
If other appliances or lights are acting oddly too, call the electric utility or an electrician about the house supply.
Book a visit so the supply at the stove and the control can be measured.
Still there?
It usually turns into control board and display repair. Book with the code and the model number.
What not to do
3C20 is not a code about the gas burners or a sensor. It concerns the electricity reaching the stove.
