Viking Range Error Code 3 flashes

Three flashes on a Viking range indicate an ignition lockout. The control board attempted to ignite the burner multiple times within its allowed retry window and never received confirmation that a flame was established. As a safety measure, the control locks out and stops attempting ignition. The fault must be diagnosed and corrected before the burner will operate again.

The 3-flash lockout is a safety response designed to prevent unburned gas from accumulating, so the affected burner should not be used until the problem is resolved. If you smell gas at any point during diagnosis, do not attempt to light the burner, ventilate the area immediately, and contact your gas utility. Other burners on the range that are functioning normally may still be safe to use, but address the lockout promptly.

Repair costs depend on which component has failed. A spark electrode or spark lead is typically an inexpensive part, and replacement is often a straightforward job, with total costs potentially ranging from around $50 to $150 depending on labor rates. A gas solenoid valve or control board is more involved, and repairs in those cases can range from $150 to $400 or more. Getting a diagnostic estimate from a qualified technician before authorizing parts is recommended.

Start by checking that the gas supply is fully open and that other gas appliances in your home are working. Inspect the spark electrode for cracks, carbon deposits, or misalignment, and check that all spark leads are securely connected and free of damage. If the gas solenoid valve is suspect, that will require testing with a multimeter and likely professional service. After correcting the underlying issue, reset the control to clear the lockout.

Resetting the control can clear the lockout state and allow the ignition sequence to run again, but it will not fix the underlying cause. If the same conditions that triggered the lockout are still present, the control will go through its retry cycle and return to lockout again. The fault must be diagnosed and repaired first, then the control reset to confirm the fix.
