Turn the oven off and keep the door closed while it cools; if there is smoke or flame, keep it shut and call 911. If it comes back, it needs a visit. ### Why would my Dacor oven overheat and show C-21? A heat source that does not shut off, a sensor giving a false reading, or blocked cooling can all let heat build. Each needs testing. ### Is C-21 on a Dacor stove dangerous? The control stops heat to prevent damage. Repeated C-21 should not be ignored; book a visit before long cooks. ### C-21 showed once during broiling on my Dacor stove. Should I worry? Once may follow very long high heat. If it repeats with ordinary cooking, have it checked. --- **[Read on the site: Dacor stove showing C-21 with an oven running too hot](https://stoverepair.center/error-codes/dacor-c-21/)** **[Book a visit with StoveRepair.center](https://stoverepair.center/schedule/)**
