KitchenAid French Door LED lights

[NVRGVUP!]

Good morning 

I have a KitchenAid French door refrigerator. # KRFF707ESS01

serial # W10695459

the Freezer LED quit working a few months back. I found them from my local supplier for $30 each.  I decided to wait because I could find some at work if I were patient.  I work at a facility that reclaims Freon and scraps old appliances.  I just have to keep an eye out.  A few weeks ago, finally one arrived.  It was a whirlpool but had the same LED’s.  I removed about 5 and thought I was set.  I searched how to remove the freezer drawers and access the LED.  No issues.  Except,  it didn’t come on.  I found out today the freezer LED is a different part number and $100 apiece.  Also the 4 LED’s on the side the refrigerator compartment are out as swell as the one towards the front on the left.  Ice maker side.  It flickered a bit but went off.  My question is what’s the difference in the lights in freezer and Frig?   What is the circuit order, as I leaned the circuit is continuous?  Do I have a bad LED Board?   $400 bucks?  I’ll keep a flash light in the door shelf beside the mayo!   Thank you. Merry Christmas
