The short answer
On the Amana ABB 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 third, 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.
- 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 — 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
- Shutoff arm or ice-level sensor holding the maker off — The first thing to rule in. 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 — Second, and close behind the first. 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.
- Ice maker module, ejector or its thermostat — Third. 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 on this list. 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
- 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.
- 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.

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. Call before cutting into any water line. A saddle valve on a supply pipe is the single commonest cause of a repair that turns into a plumbing job.
