The short answer
On the Amana 4w7z41 refrigerator family, an ice maker that has stopped filling the bucket points at what has changed recently, because a new line, a new filter or a cabinet that has just been moved explains most of the makers that have never worked properly. The brand-generic article puts the ice maker module itself at the top of this symptom. It does not lead here, and on these models it is not what the first three checks are looking for.
What you observe on these models
- The maker worked until the cabinet was moved or filtered — A change immediately before the fault is worth more than any other single clue.
- Cubes come out thin, hollow or half formed — A short fill rather than a failed harvest, which points at water rather than at the module.
- The bucket is empty and the maker never runs — Nothing cycles, nothing fills, and the cabinet is otherwise behaving normally.
- NEAR MISS — the freezer itself is not properly cold — Then the cooling page comes first and the ice is a symptom of it.
Causes, most likely first on this family
- Recently installed, moved or filtered, so no full cycle has run yet — First on this platform. A new line has air in it and a new filter needs purging, and the first cycles are short or empty by design. Judging the maker before it has settled is the commonest false alarm there is.
- Low water pressure at the valve, or a clogged filter — Second on these models. The maker fills on a timed valve opening rather than to a level, so anything that slows the water gives a short fill. The result is thin crescents and a bucket that never fills.
- Shutoff arm or ice-level sensor holding the maker off — Third, and less common than the two above. A bail arm nudged up by a bag of frozen food, or a beam sensor blocked by frost, tells the maker the bucket is full. It is the fastest thing on this list to check and the most often missed.
- Fill tube frozen shut — Fourth, and the least common of the four here. One overshooting fill leaves a plug of ice in the tube, and every fill after that misses the mould entirely. Nothing has failed electrically, which is why the module often gets replaced for nothing.
Check in this order, and why
- Ask when the line, the filter or the cabinet last changed — Start here. A maker that has never had a settled cycle is not a maker that has failed.
- Fill a cup at the dispenser if the cabinet has one, or watch a fill — Then this. A slow or hesitant flow is a supply problem, and it explains thin ice without any part being faulty.
- Look at the shutoff arm or the sensor window — Third. An arm nudged up by a bag, or a frosted window, stops a healthy maker instantly and costs nothing to correct.
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.

When to call a technician
Call once the supply, the shutoff arm, the bucket and the freezer temperature are all proven good, because what is left is the module or the valve.
