Hi Mariel,
Thank you for choosing Samsung for your refrigerator needs. We understand how important it is for your fridge to be fully operational, and we'd like to assist you with getting the main light working as expected.
There may be an issue with the light bulb or the internal connections.
We recommend checking if the light bulb in the fridge section needs replacing. If that doesn't resolve the issue, further inspection may be required.
For detailed troubleshooting steps, please refer to the Link below.
