What 8 flashes every 4 seconds means on a Viking range

The 8-flashes-every-4-seconds fault code on a Viking range indicates a gas solenoid fault. The gas solenoid is an electromechanical valve that controls the flow of gas to the burner or oven cavity. When the control board sends a signal to open or close this valve and does not receive the expected feedback, or detects an electrical anomaly in the solenoid circuit, it triggers this fault and interrupts normal operation to prevent an unsafe gas condition.

The fault is rooted in the solenoid valve circuit, which includes the solenoid coil itself, the wiring harness connecting it to the control board, and any connectors or terminals along that path. A failed solenoid coil can present as an open circuit or a short, both of which the control board can detect. Wiring issues such as damaged insulation, corroded terminals, or loose connectors can also break continuity or cause intermittent resistance changes that register as a fault.

Diagnosis should begin with a visual inspection of the wiring harness running to the gas solenoid, checking for burns, pinches, or corrosion at the connector pins. Following that, resistance testing of the solenoid coil with a multimeter will confirm whether the coil has failed internally. If wiring and connections check out and the coil reads out of specification, solenoid replacement is the appropriate repair path.

Common causes of 8 flashes every 4 seconds

  1. 01

    Failed gas solenoid coil

    Part replacement

    The solenoid coil can burn out or develop an open or short circuit internally. Testing the coil with a multimeter for resistance will confirm if it has failed and needs replacement.

  2. 02

    Loose or disconnected wiring connector

    Wiring / connection

    Vibration and heat cycling can cause the wiring connector at the solenoid to loosen or back out, breaking the circuit. Inspect the connector for secure seating and check for any pins that have backed out of the housing.

  3. 03

    Corroded or damaged terminal pins

    Wiring / connection

    Grease, moisture, and heat can corrode the terminals in the solenoid wiring connector, increasing resistance and causing the control board to register a fault. Clean or replace affected terminals and connectors.

  4. 04

    Damaged wiring harness

    Part replacement

    The wire insulation running to the solenoid can become brittle, pinched, or melted near heat sources, causing shorts or open circuits. A full visual inspection of the harness routing is needed to locate any damage.

  5. 05

    Faulty control board

    Part replacement

    If the solenoid coil and all wiring test within normal parameters, the control board itself may be failing to properly drive or read the solenoid circuit. This is a less common cause and should be diagnosed only after all other components are confirmed good.

Frequently asked questions about 8 flashes every 4 seconds

What does 8 flashes every 4 seconds mean on a Viking range?
This flash pattern indicates a gas solenoid fault. The control board has detected a problem in the circuit that operates the gas solenoid valve, which controls gas flow to the burner or oven. The range displays this fault to alert you to an electrical or mechanical problem with that valve or its wiring. Normal operation will be interrupted until the fault is resolved.
Can I fix the 8-flash gas solenoid fault myself?
Some portions of the diagnosis, such as inspecting wiring connectors for corrosion or loose pins, are within reach of a skilled DIYer comfortable working with appliances. However, any repair that involves working on or near gas components should be approached with caution, and solenoid replacement or wiring repairs near gas lines are best left to a qualified technician. Always disconnect power to the range before inspecting any internal components.
Is it safe to use my Viking range when it shows this fault?
You should not attempt to use the affected burner or oven function while this fault is active. The control board triggers this fault specifically to prevent an uncontrolled gas situation. Continuing to use the range in this condition could pose a safety risk. Stop using the affected function and have the fault diagnosed and repaired promptly.
How much does it cost to repair a gas solenoid fault on a Viking range?
Repair costs vary depending on the root cause. Wiring connector cleaning or re-termination is generally a lower-cost repair. A solenoid valve replacement typically involves part costs in the range of $50 to $200 or more depending on the specific valve, plus labor. If the control board is at fault, costs can be significantly higher, often in the $200 to $600 range or beyond for parts and labor combined.
Will resetting my Viking range clear the 8-flash fault code?
Cycling power to the range by unplugging it or switching off the circuit breaker for a few minutes may temporarily clear the fault display, but if the underlying problem with the solenoid or its wiring has not been fixed, the fault will return. A reset is useful for confirming whether a fault is persistent, but it is not a repair and does not address the root cause.
