I am seeing more and more of the W10219463 boards fail. I had 3 this week. Customers are getting very angry when I tell them that their 3-4 year old $2000.00 - 3000.00 refrigerator has a part that whirlpool no longer has available. Very few want to wait a week + for the board to be rebuilt. Does anybody know the story on these boards? Wish I had some cores to send in to have ready on my truck since it seems to be becoming a more frequent failure.
