I brought the W10151236 “Electronic Control Boar” and install it, but the LED still not work. None of the display function works, I wonder that what else’s need to repair?
Whirlpool Refrigerator KSSC48QTS02
You will want to check the wiring in the door of the refrigerator at the hinge. Look for broken, damaged or loose wiring. If this checks ok then the main control board W10219462 is faulty and would need to be replaced.
