light not working

Hi. I can not see how the lighting is set up on this unit from the parts break down. I assume you have more than one light in the refrigerator section. I found p# DA41-00676G for the L.E.D light. This looks like the control board with the lights on it. I would suspect this part first, if other lights in the refrigerator are working. Could be a main board or door switch issue, but with other lights working it does not sound like it.
