Tobin S Beaumont , TX July 13, 2015 Appliance: Maytag Ice Cube Maker JIM158XBRS1 Maytag Ice Machine Jim158xbrs1: Ice grid wire broken. How to replace Cutting Grid Kit. The folks at appliance parts pros kindly sent me a service manual for my ice maker. I eventually figured out I had a broken wire on the ice cutting grid. I ordered the new wire which was simple to replace. Now the ice maker works perfectly. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
