What this means on these models
On the 4w3n62 refrigerator this symptom is usually the water filter, because every drop that reaches the mould passes through it and a starved filter starves the ice first and the dispenser second. The 4w3n62 family is one platform carried across a run of revisions, and the trailing digits of the model number are what separate them: the fault set is shared, the part numbers are not.
What you observe on these models
- No ice at all and an empty mould — Water is not arriving.
- Small, hollow or half-formed cubes — Water is arriving but not enough of it, which is a flow problem rather than a maker problem.
- A mound of ice growing under the fill tube — Water arriving in the wrong place, which points straight at the tube and the valve.
- Cubes stuck in the mould with the arm part-way through its travel — The harvest starts and does not finish, which is the pattern that names the module.
- NEAR MISS — ice is made but will not come out of the door dispenser — A full bucket and a blocked chute is a dispensing fault, not a production fault, and it is fixed at the chute rather than at the maker.
Causes, most likely first on the 4w3n62 family
- Water filter clogged, overdue or seated wrong — Ranked first on this family. A cartridge that is not fully seated does the same thing, which is why this is worth checking whenever the fault started soon after a change.
- Fill tube frozen part-way — Next, and close behind it. Once a dribble freezes in the tube, every later fill backs up and freezes on top of it, and the mould stays empty while the plug grows.
- Water inlet valve not opening, or opening weakly — Next after those two. A partly blocked valve is worse: small, hollow or half-formed cubes arriving late, which most owners read as a freezer problem.
- Shut-off arm or optical sensor holding the maker off — Fourth, and the least likely of the four. A bail arm lifted by a bag of frozen food, or an optical eye fogged or blocked, reads a full bucket and stops production with an empty bucket in front of it.
- Body: A brand-generic article on this symptom starts with the freezer not cold enough to finish a harvest.
What to check first, and why that order
- Time a glass at the dispenser, then reseat or bypass the filter and try again — A dispenser that runs slowly and an ice maker that underfills are the same problem seen twice.
- Look at the fill tube where it enters the freezer for a plug of ice — A clear tube sends you to the valve; an ice plug means the water is arriving and stopping short.
- Listen for the short buzz of the valve at the moment of fill — A harvest with no buzz and no water is the valve or its wiring; a buzz with no water is the screen or the supply.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel or unplugging the ice maker harness — a capacitor can hold a charge after the power is off.

When this becomes a service call
Any work behind the freezer liner, at the valve body or on the harness is a service visit on these models. Call once the freezer temperature, the shut-off, the filter and the visible line are all clean and the mould still does not fill.
