Product review (5 stars): Saved Hundreds by Doing this Simple Repair Myself
I had no idea these dedicated ice machines were so expensive and the grid cutter is a very common point of failure.  My wife and kids love the ice machine, frankly I don't get it.  When I was informed ours was not working I assumed the refrigeration system had failed and I would have to replace the entire machine.  I was stunned that these machines cost more than a side by side refrigerator!  Further searching revealed the wire on these grids are a common mode of failure.  Sure enough, on closer inspection I had a broken grid wire.  Deeper inspection told me that I could remove the grid, turn on the ice machine and see if the unit, without grid, was working.  This was encouraging, as I did not want to spend $ on repair parts only to find that there were other failures.  So, when I removed the grid and turned on the machine it produced slabs of ice.  That confirmed all was working except the ice cutter.  (I actually tried to convince my wife that the slabs of ice were just as good as the cubes - I lost).  This replacement grid was an easy installation and returned the ice machine to making cubes.  I did buy the nickel chromium resistance wire to restring the grid with the broken wire.  I'll use the restrung grid when this grid breaks a wire.  Good luck
