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. Dacor range display What to do when C-21 shows on the range ### Kind of code Oven 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 to Bake 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 as Range Oven Temperature Wrong Recipes burn or come out underdone, and an oven thermometer disagrees with the temperature set on the range. ### Make Dacor A Samsung-owned luxury brand that sells professional-style gas, dual-fuel and induction ranges. ### Source Dacor 30-inch Transitional gas range user manual, troubleshooting Dacor Transitional gas and dual-fuel ranges. ## 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. 01 Turn the oven off and let it cool with the door closed; restart it once it is cool. 02 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. ### Still there? It usually turns into [bake and broil elements](https://rangerepair.center/services/bake-and-broil-element-repair/). Book with the code and the model number. ### What not to do C-21 is not the vent blockage message; Dacor gives a blocked vent its own code, C-24. ## What you may notice with it.

Turn the oven off and let it cool with the door closed; restart it once it is cool. If it comes back, it needs a visit. ### What should I do first when my Dacor range shows C-21? Switch the oven off and give it time to cool before restarting, since the code means the inside ran too hot. If it keeps heating with the knobs off, turn off the breaker. ### Why does C-21 on my Dacor only appear on long roasts? Long, hot cycles are when an oven that overshoots its temperature is most likely to cross the limit. Tell the technician the mode and setting you used when C-21 appeared. --- **[Read on the site: Dacor range showing C-21 | RangeRepair.center](https://rangerepair.center/error-codes/dacor-range-c-21/)** **[Book a visit with RangeRepair.center](https://rangerepair.center/schedule/)**
