The short answer
On the Amana AFB 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. The brand-generic article puts the ice maker module itself at the top of this symptom; on this platform it sits third, behind causes that are quicker to rule out.
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.
- The mould is full of water and nothing ejects — Fill is fine and the harvest is not, which is the one pattern that does point at the module.
- NEAR MISS — the dispenser works but the maker does not — Water reaching the door proves the supply and moves the ranking on.
Causes, most likely first on this family
- Low water pressure at the valve, or a clogged filter — Ranked first here. 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 — Next. 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.
- Ice maker module, ejector or its thermostat — Third in order. 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.
- Fill tube frozen shut — Last, and the least likely of the four. 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
- 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.
- Watch a full cycle if the maker will start one — Third. A mould that fills and never ejects is the module; a mould that never fills is not.
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. If the cabinet has been pulled out, check the water line has not been pinched or kinked before it is pushed back.

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. Call if the freezer cannot hold temperature, because the ice maker is then a symptom and the cooling fault is the job.
