Dacor Range, Oven, Cooktop Error Code C76

C76 on a Dacor Heritage appliance indicates that the control board has detected an incorrect oven type configuration, either expecting a single oven but finding a double, or the reverse. The error is confirmed after 3 seconds of continuous sensing, so it is not a random glitch. It most commonly appears after a control board replacement where the wrong board was installed or configuration settings were not properly adjusted.

C76 indicates a configuration mismatch that affects how the control board manages the oven system, so continued use is not advisable until the issue is resolved. The board may not correctly manage heating elements or safety functions if it is operating under an incorrect oven type assumption. Resolve the configuration error before resuming normal cooking use.

If the fix involves only adjusting jumper or DIP switch settings or reseating a wiring connector, the cost may be limited to a service call fee, typically in the range of $75 to $150. If a replacement control board is required, parts alone can range from $200 to $500 or more depending on the specific Heritage model, with labor adding to the total. Getting a diagnostic visit from a Dacor-authorized technician is the most reliable way to determine the exact repair cost.

In some cases, yes. If the error appeared after a control board replacement, you can verify that the correct board is installed for your specific model and check any jumper or DIP switch settings on the board. You can also inspect all wiring harness connections for secure seating without special tools. However, if the board itself needs to be replaced or reconfigured at a deeper level, a qualified technician with access to the correct parts and settings is recommended.

A power reset may temporarily clear the display, but C76 will return within 3 seconds of the control board re-sensing the configuration mismatch. Because the error is based on a persistent hardware or configuration condition rather than a one-time event, resetting alone will not resolve it. The underlying cause, such as an incorrect board or wiring issue, must be corrected for the error to clear permanently.
