The short answer for these models
When the ATMP refrigerator family stops making ice, the order in which you check matters more than the parts list. This family is a short list of model numbers rather than a whole range. Water supply first, temperature second, mechanism last — the reverse of the order most owners try.
What you observe
- 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.
- 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.
- 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 — the whole freezer section is soft and the ice is melting — That is a cooling failure, and the ice is just the first thing to show it. Use the cooling page instead.
Causes, most likely first on the ATMP line
- Bin, shut-off arm and fused ice — First on the ATMP refrigerator family. Ice that has partly thawed and refrozen into a lump lifts the shut-off arm or covers the sensor, and the maker then does exactly what it is designed to do: nothing. It is the most common cause here and the only one that is fixed by emptying a bin.
- Harvest mechanism and mould heater — Second. The mould has to let go of the ice before the ejector can sweep it, and a release that is weak gives cubes that jam mid-harvest. On these models that jam is often visible with a torch and no dismantling.
- Water getting in — Third. A fill that is short leaves cubes that are hollow or thin, which then break up during harvest and feed the jam at the top of this list. The two causes are related more often than they look.
- Compartment temperature — Fourth. A compartment that is warm enough to let cubes sweat is a compartment that will fuse them in the bin, so temperature sits behind the mechanism here but feeds it directly.
- Control and wiring to the module — Last, and rarely the answer. It is the only item that needs a meter and the only one with no visible evidence.
The order to work in on these models
- Establish whether this model has an ice maker at all — Not every cabinet in a family like this one is built with one, and a factory-fitted kit is not the same as a fitted maker.
- 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.
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. 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.

The line between an owner fix and a service call
Call once the free checks are done — bin cleared, arm reset, supply confirmed, temperature measured — and the maker still does nothing. Bring those four answers to the call and the visit is usually one trip. On the ATMP refrigerator family the module is the last thing to suspect and the first thing owners replace, which is why the order above exists.
