Viking Lighting System Failure Error Code

Error Code Explained

What Does the Viking Lighting System Failure Error Code Mean?

Viking Professional Series range hoods use halogen or LED cooktop lighting, with some models featuring dimmable LED task lights. Lighting failure is one of the most common Viking hood service calls. Depending on the model year, lighting may be controlled by the same PCB as the fan or by a separate lighting control circuit. Most Viking hood lights are accessible from below the hood by pressing or unscrewing a lamp cover.

Root Causes

Common Causes of the Viking Lighting System Failure Error Code

1

Burned-Out Bulb

Halogen bulbs in Viking hoods have a finite lifespan (typically 2,000 hours) and require replacement. LED modules last much longer but can fail.
2

Faulty Bulb Socket

Grease contamination or heat can corrode the bulb socket contacts, causing intermittent or no lighting even with a new bulb.
3

Lighting Control Board Failure

On PCB-controlled models, the lighting relay or control circuit on the PCB can fail independently of the fan controls.
