The short answer
On the Amana 51w3i90 refrigerator family, an ice maker that has stopped filling the bucket points at the things that stop a working maker from running at all, because a raised bail arm and a blocked sensor account for more empty buckets than any failed part. The brand-generic article puts the ice maker module itself at the top of this symptom; on this platform it sits fourth, behind causes that are quicker to rule out.
What you observe on these models
- The bucket is empty and the maker never runs — Nothing cycles, nothing fills, and the cabinet is otherwise behaving normally.
- 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.
- A sheet of ice under the bucket rather than cubes in it — Fill water is missing the mould, usually because the tube is partly frozen.
- 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
- Shutoff arm or ice-level sensor holding the maker off — Ranked first here. 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.
- Low water pressure at the valve, or a clogged filter — Next. 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.
- Fill tube frozen shut — Third in order. 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.
- Ice maker module, ejector or its thermostat — Last, and the only one of the four here that is not owner work. When the harvest never starts, the mould stays full and the cycle stops there. It is a real failure mode, and it empties a bucket in exactly the way several cheaper causes do.
Check in this order, and why
- Look at the shutoff arm or the sensor window — Start here. An arm nudged up by a bag, or a frosted window, stops a healthy maker instantly and costs nothing to correct.
- 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 fill tube where it enters the mould — Third. A plug of ice there explains everything downstream and is cleared rather than replaced.

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.
