The short answer
On the Amana 51w3i96 refrigerator family, an ice maker that has stopped filling the bucket points at the water supply, because a maker that fills on a timed valve opening makes thin ice the moment the pressure drops.
What you observe on these models
- 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.
- Production has slowed rather than stopped — A gradual decline is a supply story; an abrupt stop usually is not.
- 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 — water leaking at the same time — A fill that overshoots is a leak page as much as an ice page.
Causes, most likely first on this family
- Low water pressure at the valve, or a clogged filter — First on this platform. 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.
- Freezer not cold enough to finish a harvest — Second on these models. The maker waits for the mould to reach its harvest temperature. A freezer sitting a few degrees warm never gets there, so the ice stops without a single ice-maker part being faulty.
- Fill tube frozen shut — Third, and less common than the two above. 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
- Fill a cup at the dispenser if the cabinet has one, or watch a fill — Start here. A slow or hesitant flow is a supply problem, and it explains thin ice without any part being faulty.
- Put a thermometer in the freezer and leave it overnight — Then this. A freezer sitting warm stops the harvest, and the ice maker is then a symptom rather than the fault.
- 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.
