Microwave interior light does not come on, but unit heats normally

Safety first: Unplug the microwave before replacing the lamp. Avoid touching internal HV components.

• 1. Access the lamp: On many Russell Hobbs models, the lamp is accessible by removing the outer cover or a dedicated lamp cover at the rear or side.
• 2. Inspect the bulb: Check if the filament is broken or the bulb is blackened. Replace with the same type and wattage specified by the manufacturer.
• 3. Check connections: Ensure the lamp holder terminals are tight and not corroded.
• 4. Test operation: Reassemble and test. If the new lamp does not light but the microwave works otherwise, the control PCB lamp circuit may be faulty and require professional repair.
