I just had to jump on here to say THANK YOU to everyone for the tips and tricks, and I FINALLY have solved this issue permanently! After replacing the boards almost completely 4 times I was fed up with this and cut them out! I used the existing wiring harness to wire in some new LED 120v lights in each of the three areas. I used the following parts from Amazon:
DiCUNO G8 Base Wire Connector Socket, G8 LED Light Bulb Socket Adapter, Ceramic Bulb Holder, 10 Pack https://www.amazon.com/dp/B07CG6FFMH/ref=cm_sw_r_cp_api_glt_fabc_MHEXXN0FR4CSK1CA3K0D?_encoding=UTF8&psc=1

Makergroup 3W G8 LED Bulbs Dimmable 20W 25W 35W G8 T4 120V Halogen Replacements for Under Counter Lights, Under Cabinet Puck Lights Cool White 6000K 6-Pack https://www.amazon.com/dp/B088H849NR/ref=cm_sw_r_cp_api_glt_fabc_HZ72J6B43S4Q3G169YX7?_encoding=UTF8&psc=1

There is a trick to this! The lower refrigerator light and the freezer light are run in series back to the main top light. For the main top light connect the neutral (white) to the red going to the slaves. Connect the main hot (solid yellow) to the striped yellow running to the slaves. Then connect each of these two leads to the new LED light in the top. Connect a new LED to the two leads in the bottom of the refrigerator (red and gray). The freezer is trickier… Connect BOTH leads in the freezer light together! Then run a wire to the ground in the wiring harness just behind the freezer light (it’s just 4 bolts, so don’t panic). Then connect this new ground wire (now a neutral) to one side of a new LED, and connect both of the original leads (now connected together) to the other side of the LED.

If you used the parts I did it fits nicely behind the original plates with the old LED boards removed. You will need butt connectors, crimpers, and electrical tape for good measure. I actually wired two new LED bulbs in the top main area just for extra brightness. If you follow this exactly it will work! The g8 bases are optional, but will allow you to change out the bulbs easily IF they ever go bad.

All this to say that Whirlpool should have corrected this for us, and I’m in if there is a lawsuit. Problem solved for less than $30. Couldn’t be happier after dealing with this for three years! Reach out if you need more info!
