What C02 is
The service manual labels C02 as cancel redundancy, a fault on the touch panel. It involves the CANCEL/SECURE key, whose input line is either open or shorted.
Owner action, then service
Flip the breaker to off and back to on, and see whether the code disappears.
No change? Then call for service.
For the technician
The manual’s solution column names replacement of the glass and touch panel assembly, which is a technician’s job.
Ovens in the source
Dacor’s Wall Oven Service Manual, the document behind this code, covers touch-glass control on single and double ovens in both 27-inch and 30-inch widths.
Other codes to check
C01 is a shorted key entry for legacy Renaissance ovens.
If the breaker reset leaves C02 showing, San Francisco and Bay Area owners can call (415) 687-5926. Details are on Dacor wall oven repair. Tell us you tried the breaker, and read out the model number.
Model compatibility: Dacor reuses codes across series and model years, so C02 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
