Any help is appreciated here.

I know there are other threads and videos talking about how to replace a single LED module inside a fridge like mine...but... we woke up the other day and ALL of the interior LEDs no longer work.
My understanding is there are two lighting circuits inside this fridge - one for the side lights and the other for the top lights and freezer light.

So if one LED module were bad, I'd expect only one circuit to stop working...not both.

There is a smaller single LED in the crisper drawer (a different type of LED altogether) that DOES work, and I can manually turn it on and off by pushing the door switches. So, I don't believe the door switches are faulty.
I'm trying to understand if any others have experienced this, or if there are troubleshooting suggestions? Could we be talking about multiple LED module failures (at the same time)...or...something else?
Where do all the LEDs eventually terminate into something? Is there a driver module, or do they plug directly into a control board? I'm not big on the idea of paying $500 for a whole new board if that's it.

Thank you very much in advance for any help or suggestions, this is an annoying problem.

Hi,

You can check if the LED Driver Board is getting 120 Volts AC across L and N:
WPW10306786 Invrtr-Box


Its located in the very back of the refrigerator, once you pull the refrigerator out from the wall, you will see a cover over the control boards.

The LED Driver Board is the very bottom one in this photo:

The Yellow and White wires on the left side of the very bottom board is L and N.
