Interior light does not turn on when the door is opened, but the freezer cools normally.

Safety: Unplug the freezer before working on the light or switch.

• Check the bulb or LED module: Remove the light cover and inspect the lamp. Replace a blown bulb with the correct type or the LED module with a Teka replacement.
• Test door switch: Locate the door switch (usually in the frame). Press it manually; if the light flickers or never comes on, test it with a multimeter and replace if open.
• Inspect wiring: Ensure connectors to the light and switch are secure and not corroded.
• PCB driver: If the bulb and switch are good but no voltage reaches the light, the PCB light driver may be faulty, requiring PCB replacement.

Test: Restore power and open the door to confirm the light operates correctly.
