Viking Range Error Code Model Header

This error means the EOC4 electronic control board cannot find or recognize a valid model configuration header, which is a small hardware plug that tells the board what product it is installed in. Without this information, the board will not allow the range to operate at all. The error is most common after a control board replacement when the header is missing or incorrect.

No, simply resetting or power cycling the range will not resolve this error. The EOC4 board checks for a valid model header every time it powers up, so the error will return immediately if the header is still absent, unseated, or incorrect. The physical hardware issue must be corrected first.

If the fix is simply reseating a loose header connector, the cost may be limited to a service call fee, typically in the range of $75 to $150 depending on your area. If the header plug itself needs to be replaced or sourced separately, parts costs will vary. A full EOC4 board replacement, if required, can range from $300 to $600 or more for parts alone, plus labor.

If you are comfortable working on appliance electronics and the range has been powered down, you can inspect the model header connector on the EOC4 board and reseat it if it appears loose. However, if the header itself is missing or wrong for your VDSC model, sourcing the correct replacement header typically requires knowing the exact model number and may involve a qualified technician to ensure the right part is used.

The range will not operate while this error is present because the EOC4 board deliberately disables itself when no valid model header is detected. This means burners, oven functions, and ignition will all be non-functional, so there is no immediate safety hazard from the range itself. However, the appliance should not be left unattended with gas supply connected during diagnosis.
