Dacor Oven Error Code C76

C76 means the oven's control system has detected that the oven type connected does not match the configuration it expects, either single or double oven. The error is triggered after 3 seconds of sensing an incorrect configuration. It is classified as a reversible error, meaning it can be resolved once the cause is corrected. The issue typically involves wiring connections or control board compatibility.

Start by disconnecting power to the oven and inspecting all wiring harness connectors at the control board for loose or disconnected plugs. If a control board was recently replaced, confirm it is the correct board for your specific model and oven type. If wiring appears intact and the board is correct, testing the secondary control board in double-oven setups may be necessary to determine if it has failed.

Repair costs depend on the cause. If the fix is simply reseating a loose wiring connector, costs may be limited to a diagnostic service call, typically in the range of $75 to $150. If a secondary or primary control board needs replacement, parts and labor combined can range from $200 to $600 or more depending on the specific board and local labor rates.

A power reset may temporarily clear the C76 display, but the error will return if the underlying configuration mismatch is not corrected. Because the control board checks the oven type configuration on an ongoing basis, the fault will reappear within seconds of sensing the incorrect setup again. Addressing the root cause, such as a loose harness or incorrect control board, is necessary for a permanent fix.

A C76 error indicates a control system configuration issue, and it is not advisable to continue using the oven until the fault is resolved. A misconfigured control system may not properly manage heating elements or safety shutoffs. Discontinue use and diagnose the error before operating the oven again.
