What Does Error 3-FLASH-4SEC Mean?
The Viking oven 3-FLASH-4SEC error indicates an ignition lockout due to the oven failing to detect a flame after multiple ignition attempts. This issue is commonly seen in gas models, where the oven's indicator light flashes three times every four seconds, and there may be erratic temperature readings and cooking results. To resolve this, check the gas supply and reset the oven. If the problem persists, further inspection of the ignition system may be necessary.

- Inspect and clean the burner ports, ignition electrode, and flame sensor/spark electrodes for carbon build‑up or misalignment.
- Check wiring and connections between the control board and the ignition components.
- Test the gas valve and ignition module for proper operation; replace any faulty parts.
