Viking oven shows F15 and bake function is disabled or shuts off quickly.

Safety first: Disconnect power at the breaker and allow the oven to cool before working inside.

Steps to check and correct:

• Inspect bake element: Look at the lower element inside the oven for cracks, breaks, or burn spots.
• Test continuity: Remove the screws securing the bake element and pull it forward to access the terminals. Disconnect the wires and test with a multimeter. Replace the element if it is open.
• Check wiring and terminals: Inspect the wires for heat damage and replace any burnt connectors. Ensure terminals are tight when reinstalling.
• Thermal cutoff: Some Viking models have a thermal cutoff in series with the bake element. Test it for continuity and replace if open.
• Control relay: If the element and wiring are good, the bake relay on the control board may be defective and the board will need replacement.

When to call a technician: If control board replacement is required or if you are unsure how to test continuity safely, seek professional service.
