The MCD230 is the double version of the Millennia classic oven. Dacor’s diagnostic manual devotes a page to the lower oven ERC harness, and on these doubles a lower oven that stops responding is often traced to that harness rather than the ERC itself.
F6, an EEPROM checksum error, is the other code to know. Dacor’s sheet says only the clock and timer keep working after it, and the fix is a new ERC.
