What to do when C-21 shows on the ovenKind of codeHeating
The control asked for heat and the cavity did not warm the way it expected. A bake or broil element that has opened or blistered is the usual answer; the wiring to it and the relay that switches it are checked before a board is blamed.

Before you book,
in this order.
Each step comes from Dacor's own guidance for C-21 on its ovens. Follow it to the end: the last card says whether this is a visit.
Press OFF. If the oven keeps heating or you see smoke, switch it off at the breaker and keep the door closed.
Once it is cool, disconnect power for at least 30 seconds and reconnect.
If C-21 appears again, book a visit before cooking with it.

What not to do
C-21 is not a normal part of self-clean or broiling. It is the control saying the temperature is out of bounds.
