What 6 flashes every 4 sec means on a Viking range

The 6-flash fault code on a Viking range indicates a gas solenoid fault detected by the DSI (Direct Spark Ignition) board. The DSI board controls the gas valve solenoid that opens to allow gas flow when the burner is called for ignition. When the board cannot confirm proper solenoid operation, either due to a wiring fault, a failed solenoid, or an issue within the board itself, it responds by flashing the indicator light 6 times in a repeating 4-second cycle.

The gas solenoid is an electromagnetically actuated valve component that opens and closes the gas supply path to the burner. If the solenoid coil develops an open circuit, a short, or the wiring harness connecting it to the DSI board becomes damaged or disconnected, the board will detect an out-of-range signal and trigger this fault. Corrosion at connector terminals is a frequent contributor, particularly in cooking environments where grease and moisture are present.

Diagnosis begins with a thorough inspection of the wiring between the DSI board and the gas solenoid, checking for loose connectors, burnt wires, or damaged insulation. If wiring is intact, the solenoid coil resistance should be measured and compared against expected values. A failed DSI board that cannot correctly drive or sense the solenoid signal is also a possible root cause if the solenoid and wiring both check out correctly.

Common causes of 6 flashes every 4 sec

  1. 01

    Faulty or disconnected wiring to the gas solenoid

    Wiring / connection

    Loose connectors, broken wires, or corroded terminals in the harness between the DSI board and the gas solenoid are the most common trigger for this fault. Inspect all wiring connections at both the solenoid and the board for damage or poor contact.

  2. 02

    Failed gas solenoid coil

    Part replacement

    The solenoid coil can develop an open circuit or short over time, causing the DSI board to detect an abnormal signal. Measuring the coil resistance will confirm whether the solenoid has failed and needs replacement.

  3. 03

    Burned or damaged wire insulation

    Part replacement

    Prolonged exposure to heat in the range cavity can degrade wire insulation, causing shorts or intermittent open circuits in the solenoid circuit. Look for visibly charred or brittle wiring near the solenoid and burner area.

  4. 04

    Failed DSI board

    Part replacement

    If the wiring and solenoid both test correctly, the DSI board itself may have failed internally and can no longer drive or properly sense the solenoid circuit. Board replacement is required in this case.

  5. 05

    Corroded connector terminals

    Wiring / connection

    Grease and moisture in the cooking environment can cause corrosion at the solenoid wiring connectors, creating high resistance that the DSI board interprets as a fault. Cleaning or replacing corroded connector pins can resolve this without replacing major components.

Frequently asked questions about 6 flashes every 4 sec

What does 6 flashes every 4 sec mean on a Viking range?
This flash pattern indicates a gas solenoid fault on the DSI (Direct Spark Ignition) board. The DSI board controls the solenoid that opens the gas valve during ignition, and when it cannot confirm proper solenoid operation, it triggers this repeating 6-flash alert. The fault points to a problem in the solenoid itself, its wiring, or the DSI board.
Is it safe to use my Viking range when it shows the 6-flash error?
No, you should not continue using the range when this fault is active. The 6-flash code indicates a problem in the gas valve control circuit, which means the ignition system may not function reliably or safely. Discontinue use and have the range inspected by a qualified technician before cooking again.
Will resetting the Viking range clear the 6-flash error code?
Resetting the range by cutting power at the breaker may temporarily clear the fault display, but the code will return if the underlying problem is not corrected. The DSI board will re-detect the solenoid fault as soon as the range attempts to operate. A reset alone is not a fix and should not be relied upon as a solution.
How do I fix the 6-flash gas solenoid fault on my Viking range?
Start by inspecting the wiring harness between the DSI board and the gas solenoid for loose connections, damaged insulation, or corroded terminals. If the wiring is intact, test the solenoid coil for continuity and proper resistance. A failed solenoid coil or a faulty DSI board will require part replacement, and gas system work should be performed by a qualified technician.
How much does it cost to repair a Viking range with the 6-flash error?
Repair costs vary depending on the root cause. If only a wiring connector needs cleaning or reseating, labor costs may be relatively low, typically in the range of $100 to $200 for a service call. Replacing a gas solenoid or DSI board will add parts costs that can range from $150 to $400 or more depending on the specific components required for your model.
