Error code C77
Appliance Wall Oven
Quick answer

C77 means the oven sensed an incorrect 27 or 30 inch style; the manual says to call for service.

Model compatibility: Dacor reuses codes across series and model years, so C77 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
