Error codeC-F0
ApplianceWall Oven
The fault in one sentence
The Main PBA and the Sub PBA have lost communication, and C-F0 is the code that announces it. Dacor describes the cause and lists no owner steps at all.
At a glance
Display: C-F0
Cause: communication between Main and Sub PBA interrupted
Owner steps: none printed
Current models: Modernist DOB30M977 wall oven, DOC30*977D* combi oven, Modernist Pro DOP36/48M86D range
What this means for you
Because the manual offers nothing to try, the useful thing to do is write down the code. This is a link between boards inside the oven, and owners are not asked to adjust it.
Entries beside it
C-F2 covers the interrupted Main and Touch connection.
A Dacor oven in San Francisco or elsewhere in the Bay Area that displays C-F0 can be discussed on (415) 687-5926. Visit Dacor wall oven repair for background, and keep the model number to hand along with the code.
Model compatibility: Dacor reuses codes across series and model years, so C-F0 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
C-F0 means communication between the Main and Sub PBA has been interrupted.
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.
