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

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

Steps to restore interior lighting:

• 1. Check door switch: Verify that the door switch (mechanical or magnetic) is functioning. If the display indicates door open/closed correctly, the switch is likely fine.
• 2. Access light assembly: Remove the light cover inside the cabinet (usually clipped or screwed). Inspect the LED module or bulb.
• 3. Replace light source: If the LED module is visibly damaged or darkened, replace it with a Brandt-compatible LED light assembly.
• 4. Check wiring: Ensure the light connector is firmly seated and wires are not damaged.
• 5. Control board: If a new light does not work and the door switch is good, the light driver circuit on the main PCB may be faulty and require board replacement.
