Undercounter ice maker: ice slab will not release or sticks on the cutting grid

Grid-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.

Undercounter ice maker not making ice

Check power, water supply and pressure, drain (pump models stop when they cannot drain), bin sensor, cleaning status, condenser and room temperature. Scale is the most common cause on older machines.

Ice maker drain pump problems

Pump models are used when there is no gravity drain (e.g. draining to a sink). They need correct hose routing within the stated rise/run limits and tight connections. A pump that cannot discharge can stop production or cause leaks.

Commercial cuber long freeze or long harvest alarm

Long 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.

Nugget/flake machine auger overload or no ice sensed

Scale on the evaporator and auger is the most common cause of auger overload. Low water starves the freezing cylinder. Descale and check water before replacing gear motors.
