Error codeC01
ApplianceWall Oven
Quick answer
C01 on an older Dacor Renaissance wall oven is a shorted key failure, set when a key release is not seen for two minutes.
Model compatibility: Dacor reuses codes across series and model years, so C01 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
C01 is a shorted key failure: a key release was not seen for 2 minutes.
C01 is listed as a shorted key failure. The oven logs it when it does not see a key released for two minutes.
Which ovens
This is an older series. The code is documented for the Renaissance wall ovens EORS/EORD (Epicure) and MORS/MORD (Millennia), models 127, 130, 227 and 230.
What the service guide gives
The guide lists C01 under control errors with its meaning only. No steps for the owner are printed, so a technician is the one to look into a key the oven reports as shorted.
Codes with a similar feel
Newer Modernist ovens show C-d0 for a control key shorted for one minute. A C02 entry in the service manual covers a touch panel key line that is open or shorted.
