Fridge started doing screwy stuff. Wouldn't make ice in the freezer. Sometimes no water in the door. Temp wouldn't stay below ~50 degrees. Water puddles where they shouldn't be. Big hunk of ice on water line to freezer ice maker. Sometimes wouldn't make ice in the door icemaker. Sometimes it went back to mostly working right. Service technician came out to fix it during one of the times it was working. He couldn't find anything wrong. Said 'it may be the control boad' - It quit again a day later. When I called back he said great! he'd put a monitor on it and find out the actual cause of the issues. He never showed up so I bought the board and installed it. It's been working perfectly since then.
