Dacor Wall Oven C-31 Error Code

When a Dacor oven shows C-31, the control reports that its PCB temperature has risen abnormally high. In the owner’s manuals this sits in the information-code table, and the instruction beside it is a single line: call for service.

Which Dacor models show C-31

The code is listed for the Modernist DOB30M977 wall oven, the DOC30*977D* combi oven and the Modernist Pro DOP36/48M86D range. These are current Dacor lines.

What to do when it appears

Unlike C-70 or C-d1, the manual gives no restart routine for C-31. It points straight to service, so a reset attempt is not part of the printed advice. A technician is the person to check the PCB side of the oven.

Codes easily mixed up with C-31

Look at C-30 if the display shows a PCB sensor that is open or shorted instead of a high temperature. C-21 covers abnormally high internal temperature, and C-A2 is the cooling motor code that sits in the same table.
