Key facts about C01
Service guide name: Shorted Key Failure
Trigger: the oven does not see a key release for two minutes
Owner steps in the guide: none
Which Dacor ovens
C01 belongs to the older Renaissance wall ovens: EORS and EORD (Epicure), and MORS and MORD (Millennia), in sizes 127, 130, 227 and 230.
What to make of it
The code appears among the control errors with its meaning and nothing more, so a key that the oven reports as shorted is a matter for a technician.
Newer or neighbouring codes
C-d0 is the Modernist control key code, shorted for one minute.
C02 is a touch panel key line that is open or shorted.
Dacor oven repair in San Francisco
If a Renaissance oven in the Bay Area throws C01, call (415) 687-5926 and read our Dacor wall oven repair page. Have the oven’s model number and the code ready.
Model compatibility: Dacor reuses codes across series and model years, so C01 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
