Error codeC1
ApplianceCooktop
Where C1 shows up
It belongs to the Modernist induction cooktops DTI30M977BB and DTI36M977BB.
As an information code it stands for a top sensor that is shorted.
The manual’s safety shutoff section also names it: when abnormal operation makes the cooktop overheat, C1 appears and the cooktop switches off.
Steps to recover
Turn the cooktop off and back on.
If the code returns, pull the power cord for 30 seconds or longer and reconnect it.
When the problem is still not resolved, Dacor service is the next contact.
Codes close to C1
Where C1 means a shorted sensor, C0 means an open one. A different part, the IGBT sensor, is covered by C2, and a keypad issue looks like d0.
Repair help in the Bay Area
For a C1 that repeats on a Dacor cooktop in San Francisco, phone (415) 687-5926 and see Dacor cooktop and rangetop repair. Mention the model and what the cooktop did just before it shut down.
Model compatibility: Dacor reuses codes across series and model years, so C1 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
C1 means the top sensor is shorted, and it is also shown when the cooktop overheats and turns off.
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.
