Viking Range Error Code 3 flashes every 4 seconds

This flash pattern signals an ignition lockout condition. The control board attempted to ignite the burner multiple times within the allowed trial period and never detected a flame. As a safety measure, the control stops making further ignition attempts and enters lockout until the issue is resolved. The four areas to investigate first are gas flow, spark lead condition, electrode position, and the gas solenoid valve.

Resetting the range by cycling the power may clear the lockout state and allow the control to attempt ignition again. However, if the underlying problem has not been corrected, the control will go through the ignition sequence again, fail to detect a flame, and return to lockout. A reset is useful for confirming a repair was successful, but it is not a fix on its own.

Repair costs vary depending on which component has failed. Cleaning or repositioning an electrode is a low-cost fix, while replacing a spark electrode or lead wire typically adds a modest parts cost. A failed gas solenoid valve is a more involved repair and generally carries higher parts and labor costs. Total repair expenses can range from around $75 to $400 or more depending on the specific fault and local labor rates.

Start by confirming the gas supply is fully on and that other gas appliances are working. Next, inspect the spark electrode for cracks or heavy grease buildup and clean or replace it if needed. Check the spark lead wires for damage and make sure all connections are tight. If those components check out, the gas solenoid valve may need to be tested and replaced by a qualified technician.

You should not attempt to operate the affected burner while it is in lockout. The lockout condition exists specifically to prevent unburned gas from being released repeatedly. Other burners not involved in the fault may still function, but the faulty burner should remain off until the ignition system has been inspected and repaired.
