The short answer
On a 4w5ij90 refrigerator an ice fault is usually water that never arrived or cold that never reached the mould, and those two have different symptoms. The brand-generic page has to cover every fill and harvest arrangement Amana has shipped; this one starts with the fill path because that is what the listings here share. An empty bin with a dry mould and an empty bin with a slab in it are two different pages of the same story.
What you actually observe
- An empty bin and a dry, empty mould — Look into the mould rather than into the bin.
- Cubes that are small, hollow or half-formed — It is the earliest sign of a restriction.
- A buzz from the back every few hours with no water — The valve is being asked to fill and cannot.
- NEAR MISS — no ice and the freezer is also warm — Then this is a cooling fault and the ice is only the symptom that showed first.
Causes on the 4w5ij90 listings, most likely first
- A frozen fill tube — The tube that carries water to the mould sits in the coldest part of the cabinet, and once a dribble freezes in it nothing else gets through. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- A clogged or wrongly seated water filter — A cartridge past its life throttles the flow enough that the mould fills short, and a short fill makes hollow cubes before it makes none.
- The bail arm or the ice level switch left off — An optical level sensor blocked by frost or by a box does exactly the same thing.
- Cubes fused into a block in the bin — A bridged bin is a symptom of something else and a cause of the stoppage at the same time.
Check in this order, and why
- Look into the mould, not into the bin — Dry mould and iced mould send you to opposite halves of this list, and nothing else distinguishes them.
- Check the bail arm or the level sensor is clear — It is free, it takes a second, and it is the single most common reason a working ice maker stops.
- Check the filter date and that it is fully seated — Cheap, quick, and it also tells you whether the dispenser has slowed, which is the same evidence from another angle.
- Thaw the fill tube with warm water — Only after the mould has been seen dry; doing it blind tells you nothing and risks the tube.
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. Use warm water rather than heat to clear ice from a fill tube; a heat gun will melt the tube and the liner behind it. A freezer holds food safely at 0 °F (−18 °C) or below, so work quickly with the door open or move the contents first.

When to call a technician
Thawing a frozen fill tube, replacing a filter and freeing a stuck bin are owner jobs and between them they cover most ice faults. Replacing the module, the mould heater or the valve is not, because all three need the unit moved or the freezer stripped. Call if the fill valve is buzzing continuously, because that means it is being told to fill and cannot.
