I had a Kitchenaid (owned by Whirlpool) refrigerator and it had a severe design flaw. The motherboard that controlled the whole fridge was under a control panel on top of one of the 'crisper' drawers.... which was right below the water and ice dispenser, so of course when the water dripped or a piece of ice got caught in the dispenser door or whatever, the water dripped down the front of the door onto the top of that drawer where the humidity control, etc., was located.
It then seeped below the control panel and filled up the little cavity under it. This is where the motherboard for the entire refrigerator lived. At first, the LED lights shorted out, but the fridge still cooled, then the whole fridge just shut down. The first time was covered under warranty, but it started leaking again a few months later. By then, I was in the middle of a divorce and I volunteered it up to my ex-wife because I didn't want to deal with it anymore. I'm not sure if she ever got it repaired again.
