Dacor Oven Error Code C23

C23 means the ambient temperature around the oven's control board has risen above 80 degrees Celsius, triggering an automatic thermal shutdown. The oven cuts off heating and turns on its cooling fans to bring the temperature back down to 50 degrees Celsius before allowing normal operation to resume. This is a protective feature designed to prevent damage to the control electronics.

No, the oven shuts itself down when C23 is active specifically because operating with overheated control electronics risks permanent board damage. Do not attempt to force the oven back on while the error is present. Allow the cooling fans to run and the unit to cool fully before attempting to restart, and address the underlying cause before using the oven again.

Repair costs vary widely depending on the cause. Clearing a ventilation blockage costs nothing beyond your time, while a cooling fan replacement might run anywhere from $100 to $300 including parts and labor. Control board replacement on a Dacor oven is typically the most expensive repair, often ranging from $300 to $700 or more depending on the specific model and labor rates in your area.

Some causes of C23 are DIY-friendly, such as clearing blocked vents, cleaning grease from ventilation openings, and verifying the oven has proper installation clearances. If a cooling fan has failed or the control board needs replacement, those repairs require sourcing the correct parts and a higher level of comfort working with appliance electronics. If you are unsure, a qualified appliance technician can diagnose the root cause efficiently.

A reset may clear the error display temporarily, but the code will return if the underlying cause of the overheating has not been corrected. The oven's thermal protection system will trigger C23 again whenever the control board ambient temperature exceeds 80 degrees Celsius. Clearing the code without fixing the root cause can lead to repeated shutdowns or eventual board damage.
