LG Refrigerator lights don't shut off

Unusual temperature in the refrigerator led to the discovery that the bulbs weren’t turning off when the French doors were closed. Manually pushing the light pegs in the frame didn’t disconnect the power to the bulbs and the only way to turn them off was to unplug the panel inside the fridge.
Outside of that, the fridge seems to be working fine, just no interior illumination which is definitely inconvenient.
Anyone know what the cause of this malady could be? Any idea of things to check or how to fix it?
Thanks!
