The short answer first
On the 4w3in40 refrigerator this symptom is usually a jam, because a maker that cannot eject what it has already made will not start another cycle. Every model number in the 4w3in40 family is the same platform at a different point in its production run, so read your full model number before ordering anything.
What an owner actually sees
- 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 4w3in40 family
- Ice jammed in the mould, the chute or the bucket — Top of the list here. Cubes that fused into a slab after a warm spell lock the ejector arm, and the maker then reads as dead when it is merely blocked.
- Freezer not cold enough to finish a harvest — Second here. A freezer sitting a few degrees warm makes everything else in the ice circuit look faulty: water arrives, sits, and never gets cold enough to be ejected.
- Fill tube frozen part-way — Third on this platform. 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 — Fourth: possible, but not where to start. A partly blocked valve is worse: small, hollow or half-formed cubes arriving late, which most owners read as a freezer problem.
- Body: A brand-generic article on this symptom starts with the freezer not cold enough to finish a harvest.
The order to work in
- Empty the bucket completely and clear the chute by hand — Ice that comes out as a single mass rather than loose cubes tells you the cabinet warmed at some point.
- Leave a thermometer in the freezer for several hours with the door shut — A freezer holds food safely at 0 degrees Fahrenheit, which is minus 18 Celsius, or below; warmer than that and the ice maker is behaving correctly.
- 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.
Safety first
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.

Where the owner fix stops
Call rather than force anything if the ejector arm is jammed solid — levering a locked arm breaks the module that might otherwise have been fine. Any work behind the freezer liner, at the valve body or on the harness is a service visit on these models.
