Quick answer
C-23 on current Dacor ovens means the temp probe sensor is shorted; restart, then disconnect power if it persists.
Model compatibility: Dacor reuses codes across series and model years, so C-23 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

C-23 on a Dacor oven means the temp probe sensor is shorted while the oven is operating. The same entry shows up in the manuals for the Modernist wall oven DOB30M977, the combi oven DOC30*977D* and the Pro ranges DOP36M86D and DOP48M86D.
The manuals’ steps, in order
Press OFF or CANCEL, then restart the oven.
Code still on? Cut all power to the oven for 30 seconds or longer, then restore it.
