Error codeC44
ApplianceWall Oven
What C44 tells you
On an older Renaissance wall oven the control board computes a FLASH checksum and compares it with the number it has on file. C44 appears when the two numbers differ.
Series affected
Epicure EORS and EORD, and Millennia MORS and MORD, in sizes 127, 130, 227 and 230.
What owners can try
Nothing: the service guide offers no procedure. Reach out to service and describe what the display showed.
C35: not a checksum at all, but a shorted probe on the relay board.
