Transformer

This ballast transformer restores proper power regulation to the appliance lighting circuit so bulbs operate reliably and safely. Designed for use as a direct replacement to revive dim, flickering, or non-working range-hood/vent hood lamps. What it does:

• Regulates voltage to the appliance lighting system so lamps start and run consistently
• Helps eliminate dimming, flicker, or intermittent light failures tied to a faulty ballast
• Works with the hood's existing lamp sockets and wiring to restore normal lighting operation
• Supports service-level replacement where the original ballast has failed

• Service-replacement part — disconnect power to the appliance before starting work
• Handle carefully to avoid damage to terminals; secure mounting per original hardware
