Error codeC25
ApplianceWall Oven
Quick answer
C25 on an older Dacor Renaissance wall oven means the control board ambient temperature probe is shorted.
Model compatibility: Dacor reuses codes across series and model years, so C25 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
C25 means the control board ambient temperature probe is shorted (shorted thermistor).
C25 means a shorted thermistor was detected on the control board’s ambient temperature probe. It is the opposite fault to C24, where the probe is open.
Ovens this code belongs to
Dacor documents it for Renaissance wall ovens EORS/EORD (Epicure) and MORS/MORD (Millennia), models 127, 130, 227 and 230. Treat it as an older-series code.
What the service guide offers owners
Only the meaning is printed. Any probe testing is a technician’s task.
Compare
See C24 for the open-probe case, C23 for control board over-temperature, and C35 for a shorted thermistor on the relay board.
