What 5 flashes every 4 sec means on a Viking range

The 5-flashes-every-4-seconds error code on a Viking range indicates a DSI (Direct Spark Ignition) control fault. The DSI control board is the electronic module responsible for managing the ignition sequence on gas burners, including generating the high-voltage spark, monitoring flame sensing signals, and timing the gas valve operation. When this fault is triggered, the control has detected an internal error or a failure in the ignition circuit that prevents it from completing a successful ignition cycle.

Common contributors to this fault include a failed DSI control board, a disrupted power supply to the ignition module, wiring harness faults between the DSI board and connected components such as the gas valve or igniter electrodes, or a flame sensor that is not returning a valid signal to the control. The DSI module continuously monitors the ignition process and will flag a fault if the sequence does not complete within the expected parameters.

The first recommended diagnostic step is a power cycle: disconnect power to the range for at least 30 seconds, then restore it and attempt to operate the burner again. This clears any transient fault conditions that may have caused a false trigger. If the 5-flash fault code returns after the power cycle, the DSI control module itself is considered the likely failed component and replacement is the appropriate corrective action.

Common causes of 5 flashes every 4 sec

  1. 01

    Failed DSI Control Board

    Part replacement

    The DSI module itself has an internal failure and can no longer manage the ignition sequence correctly. This is the most likely cause when the fault persists after a power cycle.

  2. 02

    Transient Power Interruption or Surge

    Wiring / connection

    A brief power fluctuation can cause the DSI control to register a false fault. Cycling power to the range will clear this condition in many cases.

  3. 03

    Wiring Harness Fault

    Wiring / connection

    Damaged, loose, or corroded wiring between the DSI board and connected components such as the gas valve or igniter electrodes can cause the control to fault. Inspect connectors and wire insulation for visible damage.

  4. 04

    Faulty Flame Sensor

    Part replacement

    If the flame sensor is not returning a valid signal to the DSI control, the module may register a fault after failing to confirm ignition. A dirty or degraded sensor electrode can cause this condition.

  5. 05

    Gas Valve Communication Failure

    Wiring / connection

    If the DSI control cannot properly communicate with or energize the gas valve, the ignition sequence will fail and a fault code may be triggered. Check for wiring issues at the valve terminals.

Frequently asked questions about 5 flashes every 4 sec

What does 5 flashes every 4 sec mean on a Viking range?
This flash pattern indicates a DSI (Direct Spark Ignition) control fault. The DSI board manages the gas ignition sequence, and this code means the control has detected an error it cannot resolve on its own. The fault may be caused by a failed control board, wiring issues, or a faulty flame sensor. A power cycle is the first recommended step to determine if the fault is transient or persistent.
Will resetting the Viking range clear the 5-flash error code?
A power cycle, disconnecting the range from power for at least 30 seconds and then restoring it, can clear the fault if it was caused by a temporary power disruption or a transient control error. However, if the underlying cause is a hardware failure such as a defective DSI board or damaged wiring, the 5-flash code will return after power is restored. A reset is always worth attempting first before moving on to component-level diagnosis.
Is it safe to use my Viking range when it shows the 5-flash DSI fault?
You should not attempt to use the gas burners while the DSI fault is active. A fault in the ignition control means the ignition sequence cannot be properly managed, which could result in unlit gas being released. Avoid operating the range until the fault is diagnosed and resolved.
How do I fix the 5-flashes-every-4-seconds error on my Viking range?
Start by cycling power to the range: unplug it or shut off the circuit breaker for 30 seconds, then restore power and test the burner. If the fault clears, no further action may be needed. If the 5-flash code returns, inspect the wiring harness connected to the DSI board for loose or damaged connections. If no wiring fault is found, the DSI control board will need to be replaced.
How much does it cost to repair a DSI control fault on a Viking range?
Repair costs vary depending on whether the fix requires only a service call and wiring correction or a full DSI board replacement. A wiring inspection and reconnection alone may fall into a lower cost range, while DSI board replacement including parts and labor can range from several hundred dollars depending on your location and service provider. Viking ranges are professional-grade appliances, so obtaining a quote from an authorized service technician is advisable.
