Error codeC02
ApplianceWall Oven
Quick answer
C02 on a Dacor wall oven is a touch panel fault: a CANCEL/SECURE key input line is open or shorted. The manual suggests a breaker reset first.
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.
Plain language
What this code means
C02 is a touch panel fault: a CANCEL/SECURE key input line is open or shorted.
C02 is a touch panel fault. Dacor’s service manual describes it as cancel redundancy, meaning one of the cancel key input lines has opened or shorted, and it names the CANCEL/SECURE key.
Reset, then call
Turn the breaker off, then on, to see whether the reset resolves the problem.
If it does not, call for service.
On the technician side, the manual points to the glass and touch panel assembly.
Ovens it covers
