Viking Range Error Code 4 flashes every 4 seconds

This flashing pattern signals a gas solenoid fault detected by the control board. The solenoid valve is the component responsible for controlling gas flow to the burner or oven. The board triggers this code when it detects an electrical problem in the solenoid circuit, such as an open circuit, a short, or a wiring failure. The range should not be used until the fault is diagnosed and repaired.

No. A gas solenoid fault indicates a problem with the valve that controls gas flow, which is a safety-critical component. Using the range with this fault present risks improper gas delivery or uncontrolled gas flow. Stop using the range and have a technician inspect and repair it before resuming use.

A power reset may temporarily clear the fault code, but if the underlying wiring or solenoid problem still exists, the code will return when the control board attempts to activate the solenoid again. Resetting does not fix the fault, it only clears the stored indication. Proper diagnosis and repair of the solenoid circuit are required to resolve the error permanently.

A knowledgeable DIYer can start by inspecting and reseating wiring connectors at the solenoid, which requires no special tools and no parts. However, replacing a gas solenoid valve or diagnosing a control board involves working near gas supply components, so professional service is strongly recommended for those steps. If you smell gas at any point during inspection, leave the area and contact your gas utility immediately.

Repair costs vary depending on what has failed. If only a wiring connector needs reseating or repair, the cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing the gas solenoid valve itself generally runs $150 to $400 including parts and labor. A control board replacement, if that is found to be the cause, can bring costs to $300 to $600 or more depending on the model.
