What the DSI LED Continuous error code actually means

Your Viking range has detected a problem with the electronic ignition control board, which is responsible for lighting the gas burner safely. The indicator light on that board is staying on solid, which means the board has stopped working correctly and needs attention. Cycling the power may clear the issue, but if the light comes back on, the ignition control board will need to be replaced.

Questions people ask about DSI LED Continuous

What does DSI LED Continuous mean on a Viking range?
DSI LED Continuous means the Direct Spark Ignition control board has detected a fault and its status LED is staying on solid rather than cycling normally. The DSI board manages the gas ignition sequence, and a continuous LED indicates the board has entered a locked-out fault state. This fault requires a power cycle as a first diagnostic step, and if it persists, the DSI board itself likely needs to be replaced.
Is it safe to use my Viking range when the DSI LED Continuous fault is active?
When the DSI board is in a faulted state, the ignition control system is not operating correctly, which means the gas ignition sequence may not complete safely or reliably. It is best to avoid using the affected burner until the fault is diagnosed and resolved. Attempting to operate a burner when the ignition system is compromised can pose a safety risk.
How much does it cost to replace a DSI control board on a Viking range?
The cost to replace a DSI control board on a Viking range typically falls in the range of $150 to $400 or more for the part alone, depending on the specific model. Adding professional labor costs can bring the total repair to $250 to $600 or higher. Obtaining a model-specific part quote before scheduling service is recommended, as Viking replacement components can vary significantly in price.
Will resetting the power clear the DSI LED Continuous fault on a Viking range?
A power cycle is always the first recommended step: disconnect the range from power for at least 30 seconds, restore power, and retry ignition. If the fault was caused by a transient voltage event or a temporary error, the reset may clear it completely. However, if the LED returns to a continuous-on state after the power cycle, the DSI control board has an internal failure and a reset will not resolve it permanently.
How do I fix the DSI LED Continuous fault on my Viking range?
Start by cycling the power to the range for at least 30 seconds, then restore power and attempt to use the burner again. If the fault clears, no further action is needed. If the LED remains on continuously, inspect all wiring connections to the DSI board for looseness or heat damage, and check the igniter and flame sensor circuits for shorts or open conditions. If no wiring issue is found, the DSI control board requires replacement.
