Dacor Range, Oven, Cooktop Error Code C44

C44 on a Dacor Heritage appliance means the control board has detected a FLASH memory checksum failure. The board calculates a checksum of its stored firmware and compares it to a saved reference value. When those values do not agree, C44 is triggered to indicate that the firmware data has been corrupted or is invalid. This is a control board level fault, not a sensor or wiring issue.

A C44 error means the control board's firmware integrity has been compromised, which can cause unpredictable behavior in the appliance's control functions. Continued use is not recommended until the fault is resolved. Shut the appliance off and disconnect power until the control board has been inspected and repaired or replaced.

Repair costs for a C44 error typically involve the price of a replacement control board plus labor. Control boards for Dacor Heritage appliances generally range from around $150 to $400 or more depending on the specific model. Labor for a qualified technician to diagnose and replace the board commonly adds $100 to $250, putting total repair costs in the range of $250 to $650 or higher in some cases.

C44 points to internal firmware corruption within the control board, which is not something that can be resolved through user-level adjustments or cleaning. Replacing the control board is the standard repair. Unless you have experience handling electronic control boards and following proper ESD precautions, this repair is best handled by a qualified appliance technician.

A power reset is unlikely to permanently clear C44 because the underlying cause is FLASH memory corruption within the control board. The checksum failure will recur whenever the board performs its integrity check. If the error returns immediately after a reset, the control board will need to be replaced.
