I have a Whirlpool WRS325FDAM04 refrigerator whose 3 LEDs lights are all
flickering (for years) and I want to surprise fix it for my wife's birthday
coming up.

I think I need to replace the main 120VAC LED control module at the top of
the refrigerator in the front of the roof which I think also is wired in
series to two other LED lights, one of which is in the back behind the
refrigerator crisper and the other of which is in the back of the freezer
down low.

I just want to make sure I get the right part numbers, specifically for the
control module but also for the LED lights as I don't know which is busted.

Where can I look up the right part numbers for the three modules to be
sure?

 
I started with a Google search:
<https://www.google.com/search?q=Whirlpool+WRS325FDAM04+power+supply>
I picked the first parts supplier (Coast Parts):
 
Parts suppliers usually have online exploded views of their equipment.

I tried to find the LED control panel, but failed.  It's probably on
here somewhere:

The best I could do is:
<https://www.coastparts.com/lookup/257008/1693023#diagram>
I found one board with electronics (item #6), which is an "adaptive
defrost control":

If the LED's are "flickering", it means that they will probably light
correctly when power is applied continuously.  Therefore, the LED's
are probably not defective and the flashing problem is elsewhere.  The
the LED's were totally off, then I would worry about defective LED's.

I think this is what the OP needs as I had the same issue.

They're wired in series so if one is bad, it will destroy the other.
Most people say R15 or C4 (electrolytic) go bad but you never know.

That seems likely except the photos of the part shows four LED's
instead of three. 

The video on the Amazon pages shows the flickering lights.

There's no way to test it so you don't repair it. You replace it.

Note that the photo of the PCB on the Amazon page shows that the board
has 34 test points.

That might lead me to suspect that there might be a way to test it.
