Identifying the fault
When you open your refrigerator door and the light doesn’t come on, this may indicate a problem. Possible causes include a lighting malfunction or the opening and closing mechanism.

Each of these components may be at the root of the problem. This article will guide you in identifying the source of the malfunction and carrying out the necessary repairs.

Checking the socket-outlet and other components
For check plug condition Inspect it visually for moisture or burn marks. Plug in another device to confirm correct operation.
Then use a multimeter set to AC at a voltage above 240 V; a reading of around 230 V indicates that the plug is operational. To test the fridge switch, simulate closing the door by pressing it.
If the light doesn’t go out, use a multimeter in continuity mode Unplug the fridge, remove the switch and place the touch points on its terminals. Finally, check that the thermostat knob is positioned above 1; if necessary, replace the thermostat by following the appropriate steps.
