Interior light does not turn on when the door is opened, but the cooler otherwise operates normally.

Safety: Unplug the wine cooler before replacing any light components.

• Check door switch: Verify that the door switch or sensor is working (see E7). If the control thinks the door is closed, the light will stay off.
• Inspect light module: Remove the light cover inside the cabinet. Check for visible damage or discoloration of the LED module or bulb.
• Test voltage: With the unit briefly powered and door open (only if safe and using insulated probes), check for voltage at the light connector. Then unplug again.
• Replace light module: If voltage is present but the light is off, replace the LED light module or bulb with a Teka-compatible part.
• PCB driver: If no voltage is present and the door switch is good, the light driver circuit on the main PCB may be faulty and require board replacement.
