Error codeC2
ApplianceCooktop
Quick answer
C2 signals an open IGBT sensor. The manual calls for a restart, a 30-second unplug and then a service center.
Model compatibility: Dacor reuses codes across series and model years, so C2 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
C2 means the IGBT sensor is open.
The C2 message
If your Modernist induction cooktop (DTI30M977BB or DTI36M977BB) displays C2, the IGBT sensor is open. This is a different sensor from the top sensor behind C0 and C1.
Owner steps
The manual groups C2 with the sensor codes. Switch the cooktop off and restart it; if C2 persists, unplug the cord for 30 seconds or more, plug it in again, and call a Dacor service center if nothing changes.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
