Kenmore refrigerator not making ice

Our icemaker quit less than 1 year old… Sears sent 3 repairmen, replaced icemaker 3 times and still has not made ice. We got money back, but need to salvage it if we can. We reset with paper-clip, it goes thru motions, bail up and down etc. Set to ultra-ice, everything we know, still no ice. Anybody got any ideas??
