The short answer
Ice production on AERC cabinets depends on three things in series: water reaching the mould, the compartment being cold enough to freeze it, and the harvest mechanism clearing it. This family is a short list of model numbers rather than a whole range. Almost every complaint on this family resolves to the first two, which are checkable without opening anything.
What an owner actually sees
- Cubes are hollow, small or misshapen — A partial fill: water is arriving but not enough of it, or not for long enough, which points at pressure or the valve rather than the mechanism.
- No ice at all, and the mould is dry — A dry mould means water never arrived. That moves the whole diagnosis upstream to the supply, the valve and the line.
- Ice arrives slowly and the bin never fills — Production that is merely slow is usually a temperature story — the compartment is not cold enough to complete a cycle in the time the control allows.
- Cubes fuse into a single lump in the bin — Partial melting and refreezing, which means the compartment is cycling above freezing somewhere in its cycle, or the bin sits in warm air.
- NEAR MISS — water on the floor rather than in the mould — That is a supply-line or fill-tube leak and belongs on the water-leak page for this family.
Causes, most likely first on the AERC line
- The compartment is not cold enough — First on the AERC refrigerator family. An ice maker is a thermostat with a motor attached: it will not harvest until the mould reaches its release temperature. A freezer holds food safely at 0 °F (−18 °C) or below, and a compartment sitting above that will make ice slowly or not at all while looking perfectly normal.
- Air reaching the mould — Second. Cold reaches the mould through a duct, and on cabinets where that duct runs past storage it is easy to block with a package. The ice stops while the rest of the cabinet stays fine, which is the tell.
- Water arriving at the mould — Third. Supply faults produce dry or under-filled moulds, which is a different picture from the slow production that the two causes above give.
- The ejector and what is in the bin — Fourth. A shut-off arm resting on a heap of fused cubes stops production as effectively as a broken module, and costs nothing to find. Empty the bin and watch a cycle before spending money.
- Module or control electronics — Last. Replacing a module for a fault that is really a temperature fault is the single most common wasted repair on this complaint.
What to check first, and why that order
- Look in the mould — Dry, full of water, or full of a solid block — three states, three different halves of the list.
- Check the supply valve and the line behind the cabinet — Free, fast, and it settles the most common cause before anything else is touched.
- Measure the compartment temperature — Ice that is slow rather than absent is usually a temperature story, and a thermometer answers it in a few hours.
- Only then watch a harvest cycle — By now the water and temperature questions are answered, so what the mechanism does is actually informative.
Before any panel comes off
Safety
Isolate the cabinet at the plug or the breaker before any cover comes off, and close the water shut-off before touching the line. Shut the water supply off before disturbing any connection, and never clear a frozen fill tube with a metal tool or a naked flame: warm air only, with the power isolated. A freezer holds food safely at 0 °F (−18 °C) or below. If ice is fusing in the bin, the compartment is spending part of its cycle above that, so check the frozen food as well as the ice maker.

When to call a technician
Call when water has been confirmed at the valve and the compartment is at temperature and there is still no ice — that combination points inside the machine, where a meter is needed. Call sooner if the supply line is weeping at a connection, because a slow leak behind a cabinet does more damage than the repair costs. On the AERC refrigerator family everything upstream of the inlet valve is owner work and everything downstream of it is not.
