Questions
about C-21.

Can I clear C-21 myself?
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.

Back to your everyday

Still showing C-21?

Book with the code written exactly as the stove shows it, the full model number, and whether you notice any smell of gas or hot wiring — when there is a code, that is where the diagnosis starts.
