Guide · Ice MakerLong freeze usually means poor heat rejection or water problems; long harvest usually means scale or harvest components. Do the safe checks; refrigeration work goes to an EPA 608-certified tech.
Guide · Ice MakerSmall or thin cubes usually mean not enough water: low pressure, a clogged filter or inlet screen, or water leaking out of the pan (loose drain cap, check valve leak-by). Cloudy ice usually means scale. In bins that are insulated but not refrigerated, cubes naturally shrink and clump over time.
Guide · Ice MakerGrid-cutter (slab) ice makers freeze a sheet, release it during harvest and let a heated wire grid cut it into cubes. Most release problems come from an unlevel cabinet, scale on the evaporator plate, or a cutting grid that is unplugged or not heating. Harvest switches and probes are next.
