Error codeC33
ApplianceWall Oven
Quick answer
C33 on an older Dacor Renaissance wall oven means the relay board ambient temperature is above 80°C and the oven shuts down.
Model compatibility: Dacor reuses codes across series and model years, so C33 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
C33 means the relay board ambient temperature is above 80°C and the oven shuts down.
C33 is the relay board’s ambient over-temperature code. The guide says the ambient temperature at the relay board is above 80°C; the oven then shuts down with the cooling fans on until it drops to 50°C.
Older series
It appears for Renaissance wall ovens EORS/EORD (Epicure) and MORS/MORD (Millennia) 127/130/227/230.
For the owner
Nothing is listed for you to reset. Further checks on the relay board are technician work.
Related codes
C23 is the same over-temperature fault at the control board. The relay board probe faults are C34 (open) and C35 (shorted).
