Cassidy K Cornelius , NC May 13, 2014 Appliance: KitchenAid Ice Cube Maker KUIA18NNJS4 Kitchenaid Ice Machine Kuia18nnjs4: The compressor was not activating therefore the machine was not making ice. How to replace Control Board. I had to replace the control board. The repair estimate from a local appliance company was $530.00. So I decided to order the part here for $200 and do the installation myself. Everything on the control board is "plug and play" and very simple ONCE you have access to it. However, gaining access to the board is the tricky part. Unless you have the long enough tools, it can be a real challenge. I had to first remove the water drain unit. Next, the ice cutting wire cover. Then remove the ice cutting wire unit (disconnecting the appropriate plugs) in sequence. Then unscrewed the control board cover. The two screws that hold up the back of the cover very difficult to get to, however with the proper tools I'm sure the job would have gone much smoother. I then simply unscrewed the unit and unplugged the connections, replaced the new board and put everything back in place. The unit is now making ice wonderfully and it seems as though my problems with this are solved. I'll be honest and say that it took me close to 3 hours to complete this project. Had I known it would have taken that long, I would have gone to the home center and purchased a nut driver with the correct length shaft. that would have easily shaved an hour or so off the project. 10 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
