The short answer for these models
Before opening anything, find out whether water is reaching the mould. A dry mould and a wet one send you to completely different halves of the problem, and the difference takes ten seconds to establish. The KS models take the same faults in a different order: a glazed door leaks far more heat than a solid one by design, so the same fault reads as more severe on a glass-door unit and the baseline you are judging against has to change with it, and the door and glazing checks therefore come before anything else.
What you actually see
- How your KS unit is built — the check that comes before the list — Check the door material. Glass changes the baseline: longer runs, some sweating and a warm shelf by the door are normal there.
- Cubes are hollow, small or only half formed — Partial cubes point at fill volume and at timing rather than at freezing.
- A sheet of ice under the bin or over the mould — Ice where ice should not be is water finding a path it should not have.
- NEAR MISS — the whole cabinet is warm and the ice is only one symptom — Then cooling is the fault and ice is a consequence. The page about a unit that will not cool is the one to read.
Causes, most likely first on this family
- The bin, the arm or the switch is out of position — Common, free to correct, and one of the few faults that produces a perfectly healthy machine doing nothing. On a KS unit this rises to the top of the order, because the identification step above changes what it proves — so the door and glazing checks answer more in five minutes than the rest of the list answers in an hour.
- The fill valve, the mechanism or its heater — It sits at the bottom of the order deliberately: everything above it is cheaper, more common and checkable without tools.
Check in this order, and why
- First — look at the mould and the bin — Look at the mould before you look at anything else. Dry sends you upstream to the supply and wet sends you downstream to the harvest.
- Second — confirm the compartment is properly cold — Check the temperature before blaming the mechanism, because a marginal cabinet fails at ice first. On these models this is the step the construction changes: what you found at the step above decides how much weight to give what you find here.
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. Clear ice with warm water and patience, never with a blade, a screwdriver or a hot-air gun: the tubing and the mould behind the ice are thin and they puncture. Where a water line is fitted, shut its valve before disturbing anything, and dry the floor as you go.
Where the owner job ends
Book a visit once the supply, the shut-off arm, the bin and the compartment temperature have all been checked and ice still will not come. Book sooner if the same unit has also started running warm, because that pairing points past the ice mechanism to the cabinet itself.
