Error codeC41
ApplianceWall Oven
Quick answer
C41 shows when the A/D reference readings check, which confirms the RTD oven temperature readings, fails.
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
A/D reference readings failed: safety check that RTD oven temperature readings are correct.
C41 on a Dacor wall oven is labeled A/D Reference Readings in the Renaissance service guide. It is a safety check that makes sure the RTD oven temperature readings are correct, and the code appears when that check does not pass.
Which series
This is an older series. Renaissance EORS/EORD (Epicure) and MORS/MORD (Millennia) wall ovens, 127/130/227/230.
What the manual expects
There is no owner procedure for C41 in the guide. If the oven keeps showing it, stop relying on its temperature and arrange a visit, since the code concerns whether the temperature readings can be trusted.
Related codes
C42: E2 checksum failure on the control board, another self-check code.
For a Dacor oven that displays C41, phone (310) 742-1907. Give the model number, say what the display showed, and mention what was done before calling. More on Dacor wall oven service is on our service page.
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.
