The short answer
A 4w3n62 ice maker that has stopped is far more often a supply problem than a mechanical one. Where the brand-generic article opens with the module, this one opens with the fill tube, because on this platform that is the part that freezes first. Look in the mould before you order anything.
What you actually observe
- An empty bin and a dry, empty mould — Look into the mould rather than into the bin.
- Cubes that are small, hollow or half-formed — It is the earliest sign of a restriction.
- Ice is still made but far more slowly than before — A partial restriction, not a failure.
- NEAR MISS — no ice and the freezer is also warm — Then this is a cooling fault and the ice is only the symptom that showed first.
Causes on the 4w3n62 listings, most likely first
- The bail arm or the ice level switch left off — A wire arm knocked up by a bag of frozen food tells the ice maker the bin is full, and it obediently stops. An optical level sensor blocked by frost or by a box does exactly the same thing. The short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- A failing water inlet valve — Sediment in the inlet screen restricts the flow at exactly the wrong moment. It is a part, not a clean, on most of these.
- A kinked or shut supply line — Low supply pressure gives short fills and hollow cubes long before it gives none. Check the line is straight behind the unit before you blame the appliance.
- A failed ice maker module or motor — The module drives the harvest and times the fill, and when it fails the mould sits full of ice and never turns. A mould you can see ice in, with nothing in the bin, points straight here.
Check in this order, and why
- Check the bail arm or the level sensor is clear — It is free, it takes a second, and it is the single most common reason a working ice maker stops.
- Thaw the fill tube with warm water — Only after the mould has been seen dry; doing it blind tells you nothing and risks the tube.
- Confirm the freezer is actually cold enough — The harvest will not release until the ice is hard, so a warm compartment stalls a perfectly good ice maker.
- Follow the supply line behind the cabinet — You are looking for a kink against the wall and for a valve that was never fully reopened.
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. Never free a stuck mould or a jammed auger with a metal tool while the unit is powered: the harvest motor can start without warning and the mould heater is live. Shut the water off at the supply valve before you disturb any fitting.

When to call a technician
The line on these models is whether the fix is in front of the mould or behind it. Water supply, filter and bin are all reachable; the module, the thermostat and the heater are behind the ice maker and need it out. Call the same day if there is water running out of the freezer as well as no ice, because that is a valve stuck open.
