Interior light (on models equipped with a viewing window) does not turn on, but the fryer otherwise works.

Safety first: Unplug and allow the unit to cool before accessing the lamp area.

• Access lamp: On windowed Swan models, the lamp is usually behind a glass or metal cover inside the cavity. Remove the cover screws to access the bulb.
• Inspect bulb: Look for a broken filament or darkened glass. Replace with the same type and wattage, rated for high temperature.
• Check connections: Ensure the lamp holder contacts are clean and the wires are secure.

If a new bulb does not light, the lamp driver on the PCB may be faulty; this typically requires PCB repair or replacement.
