What C-21
actually means.
C-21 is Dacor's high-heat code: the internal temperature climbed further than it should. The control stops the oven to protect it and the cabinets around it.

What to do when C-21 shows on the rangeKind of codeOven heating
The oven under the burners called for heat and the cavity did not warm the way the control planned. On an electric oven a bake or broil element that has burned open is the usual cause; on a gas oven the igniter and the valve it opens come first. The wiring and the relay are checked before the board takes the blame.
Usually leads toBake and broil elements
An electric range oven that stays cold, heats only from above or below, or will not broil, traced to the elements, their terminals or the relay that switches them.
Shows up asRange Oven Temperature Wrong
Recipes burn or come out underdone, and an oven thermometer disagrees with the temperature set on the range.

Before you book,
in this order.
Each step comes from Dacor's own guidance for C-21 on its ranges. Follow it to the end: the last card says whether this is a visit.
Turn the oven off and let it cool with the door closed; restart it once it is cool.
If the oven seems to keep heating with the knobs off, switch the range off at the breaker; if C-21 repeats, book a visit.
What not to do
C-21 is not the vent blockage message; Dacor gives a blocked vent its own code, C-24.

Dacor range repair
Gas range
Open flames on top and a gas-fired oven below, all fed by one supply line behind the range and lit by igniters rather than a match.
Dual-fuel range
Gas burners on top and an electric oven below, the combination most professional-style ranges use, needing both a gas line and a 240-volt circuit.
Induction range
A glass top that heats the pan itself through copper coils and power boards, over an electric oven, with electronics doing almost all the work.
