Interior light does not turn on when the door is opened.

Safety: Unplug the wine cooler before replacing any light modules or accessing wiring.

Steps to restore interior lighting:

• Check door switch: Verify that the door switch (mechanical or magnetic) is functioning. If the control panel still detects door open/closed correctly, the switch is likely good.
• Inspect light module: Locate the LED light assembly inside the cabinet (often at the top). Remove its cover carefully.
• Check connections: Ensure the light module connector is firmly seated and wires are not damaged.
• Replace LED module: If the module shows signs of burning or still does not light with good power, replace it with a Haier-compatible LED light assembly.
• Test operation: Restore power and open the door to confirm the light turns on.

Note: If both the light and door-ajar indication fail, suspect the door switch or control PCB.
