Interior light (if fitted) does not turn on, but the unit otherwise works normally.

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

• Locate lamp cover: Inside the cooking chamber, find the lamp lens or cover.
• Remove cover: Unscrew or unclip the cover to access the cavity lamp.
• Replace lamp: Fit a new lamp of the same type, voltage, and wattage rating specified for your Russell Hobbs model.
• Check connections: Ensure the lamp holder contacts are clean and secure.
• Driver circuit: If a new lamp does not work, the lamp driver on the control PCB may be faulty; PCB replacement may be required.
