The short answer
When the CT family stops making ice, the useful first observation is whether the mould ever fills. A dry mould and a full-but-unfrozen mould are different faults with different repairs, and the brand-generic page treats them together.
What you observe
- Hollow, small or slow-forming cubes — Partial supply restriction, often a part-closed stop tap or a clogged filter.
- Ice tastes or smells wrong — An old filter or long-stored ice absorbing cabinet odours rather than a mechanical fault.
- Ice production stopped after a filter change — Air in the line or a filter not seated home, and it clears once the line is purged.
- Cubes fused into a single block in the bin — Slow production and repeated partial melting, which points at compartment temperature.
- NEAR MISS - the whole cabinet is warm — Fix the cooling fault first; ice production is the first thing to stop when a cabinet warms.
Causes, most likely first on CT
- Freezer compartment not cold enough — Ranked first on the CT family: a compact cabinet has little cold reserve, so any door opening leaves the module warm for a long time. The order below follows the air path rather than the refrigeration circuit, which is a family property and not a model one. This moves above water supply: stop tap, line or a frozen fill tube, which leads the brand-generic order, because this family is a single build with fixed access points.
- Water filter overdue or restricting — Second: many units in this class have no filter at all, in which case the restriction is in the line itself.
- Water supply: stop tap, line or a frozen fill tube — Third: where a module is fitted to this class of unit at all, its supply is a small-bore line that blocks or freezes readily.
- Arm, switch or the ice-off setting — Fourth: last only because it is free to check: a raised arm or an off setting produces a total no-ice with nothing broken at all.
- Ice module, fill valve or the harvest mechanism — Last: the module on this class of unit is small and inexpensive but not always accessible.
Check in this order, and why
- Check the arm or the ice-off setting first — It takes seconds and explains a total no-ice with nothing broken.
- Purge several litres through the dispenser where one is fitted — It clears air after a filter change, which is the commonest post-service complaint.
- Look at the mould: is it dry or full? — This single observation splits supply faults from freezing and harvest faults.
- Check the compartment temperature before blaming the module — A freezer holds food safely at 0 °F (−18 °C) or below; above that, no module will keep up.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A loaded cabinet is heavy and top-heavy once the doors are open, so empty it before moving it, and leave the sealed system alone entirely.
When to call a technician
Taps, filters and the arm setting are owner work. Call when the fill tube has frozen repeatedly, when the valve is suspect, or when the module has to come out, because all three sit behind fixed panels on this family.
