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.

Before you start

Unplug the unit (or shut off the breaker) before removing panels or touching wiring.
Never open or recharge the sealed refrigerant system: compressor replacement, leaks and refrigerant work go to an EPA 608-certified technician.

Countertop ice maker shows 'Add Water' with water in the reservoir

These units detect water with a float, probe or wire sensor in the reservoir and a small pump that lifts water to the tray. Scale on the sensor, a blocked reservoir screen, a stuck float, very pure water or a weak pump can all trigger a false Add Water.

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.
