What C41 reports
In Dacor’s Renaissance guide the code is filed under A/D Reference Readings. The check exists to insure that the RTD oven temperatures are right, so C41 tells you that verification did not succeed.
Where it applies
Epicure ovens: EORS and EORD
Millennia ovens: MORS and MORD
Sizes 127, 130, 227 and 230
An older Renaissance generation
Owner action
The guide hands owners nothing to try. Since the code questions whether the oven’s temperature figures are reliable, do not keep cooking on the assumption that they are; get the oven diagnosed.
For a Renaissance oven that shows C41, phone (415) 687-5926 and have the code and your model number ready, plus a note of whether the oven still heats. The Dacor wall oven repair page lists what we handle in San Francisco and across the Bay Area.
Model compatibility: Dacor reuses codes across series and model years, so C41 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
The A/D reference readings safety check on the RTD oven temperature readings failed.
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.
