Freezer interior light does not turn on when the door is opened, but cooling appears normal.

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

Step-by-step checks:

• 1. Test door switch: Press the door switch manually and listen for a click. If the switch feels loose or does not click, test it with a multimeter and replace if faulty.
• 2. Inspect light assembly: Remove the light cover inside the freezer. Check for obvious damage or discoloration of the LED module or bulb.
• 3. Replace light source: On models with replaceable bulbs, install a new bulb of the correct type. For LED modules, replace with a Gram-compatible LED light assembly.
• 4. Check wiring: Ensure the light connector is firmly seated and wires are not damaged.

When to call a technician: If the light still does not work and the PCB is suspected, a technician should diagnose and possibly replace the control board.
