Error codeC23
ApplianceWall Oven
Quick answer
C23 on an older Dacor Renaissance oven means the control board ambient temperature is above 80°C, so the oven shuts down with the cooling fans on.
Model compatibility: Dacor reuses codes across series and model years, so C23 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
C23 means the control board ambient temperature is above 80°C and the oven shuts down.
C23 is an ambient over-temperature code. The service guide says the control board ambient temperature is above 80°C. When that happens, the oven shuts down and keeps the cooling fans running until the ambient temperature falls to 50°C.
Series
This belongs to an older line: Renaissance wall ovens EORS/EORD (Epicure) and MORS/MORD (Millennia) 127/130/227/230.
Owner view
The guide describes the shutdown with the fans running and prints no reset steps for the owner.
Related ambient codes
The relay board has its own version of this fault, C33. Probe faults on the control board show as C24 when open and C25 when shorted.
