The short answer for these models
A ACFM refrigerator that has stopped producing ice, or produces hollow or undersized cubes, is describing its water supply more often than its ice maker. The table on this page covers a broad group of model numbers across several stems. The distinction decides whether this is a plumbing job or a parts job.
The observations that separate this fault from its neighbours
- 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.
- It stopped after the cabinet was moved or the filter changed — The strongest clue on this page, because it names the work that disturbed the water path.
- No ice, but the mould holds water or a solid block — Water arrived and did not leave. Either the harvest never ran or the ice fused before it could.
- The maker works, then stops after a few cycles — Something is satisfied and then lost — usually water pressure recovering slowly, or a shut-off arm or sensor catching on the bin.
- 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 ACFM line
- The compartment is not cold enough — First on the ACFM 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.
- Airflow to the ice compartment — 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.
- Harvest mechanism and 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.
- The ice maker module — 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
- Empty the bin and look at the ice already in it — Fused lumps, hollow cubes or nothing at all each name a different cause, and the bin is free to inspect.
- Reset the shut-off arm or clear the sensor path — Done second because it is the cause most often found after the bin is emptied.
- Check the fill tube for an ice plug — A plug is cleared with warm air and patience. Never with a tool — the tube deforms and then leaks.
- Confirm the supply side — Tap, line and connection, in that order, so that a dry mould is explained before parts are considered.
Safety first
Safety
Power off and water off before the ice maker is disturbed; a capacitor can hold a charge after the power is off. Sharp metal edges sit inside the ice compartment on cabinets of this build, and the mould release can be hot immediately after a harvest cycle. Ice that thaws and refreezes is a temperature warning, not just a nuisance: a freezer holds food safely at 0 °F (−18 °C) or below, and fused cubes say the compartment is not holding it.

The line between an owner fix and a service call
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 ACFM family everything upstream of the inlet valve is owner work and everything downstream of it is not.
