Error codeC24
ApplianceWall Oven
Quick answer
C24 on an older Dacor Renaissance wall oven means the control board ambient temperature probe is open.
Model compatibility: Dacor reuses codes across series and model years, so C24 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
C24 means the control board ambient temperature probe is open (open thermistor).
The C24 code reports an open ambient temperature probe on the control board. The service guide words it as an open thermistor detected.
Where it applies
It is listed for the Renaissance wall ovens EORS/EORD (Epicure) and MORS/MORD (Millennia) 127/130/227/230, an older series from Dacor.
Owner guidance
The guide gives no restart or cleaning step for this one. Probe and thermistor checks are technician work.
Closely related codes
When the same probe reads shorted instead of open, the display shows C25. C23 is the control board over-temperature code, and C34 is the open-thermistor code for the relay board.
