The short answer
When a 4w5j90 refrigerator stops making ice, the useful first question is whether it is still trying. The generic Amana answer cannot tell you what a normal cycle sounds like on your cabinet; here the fill hum and the harvest drop are both audible, and their absence is the diagnosis. Listen for a day before you take anything apart.
What you actually observe
- 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.
- Water in the bin or ice on the freezer floor — That needs attention sooner than a bin that is merely empty.
- NEAR MISS — no ice and the freezer is also warm — Start from the cooling page instead.
Causes on the 4w5j90 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. A tube that has iced over gives a perfectly healthy ice maker with nothing to work with. 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. It is the cheapest thing on the list and the most often overdue.
- A failing water inlet valve — The valve opens for a few seconds per cycle, and a weak solenoid or a silted screen turns that into a trickle. A buzz with no water is the signature.
- 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. Empty it, wash it, dry it and watch what happens over a week.
Check in this order, and why
- 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.
- 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.
- Confirm the freezer is actually cold enough — The harvest will not release until the ice is hard, so a warm compartment stalls a perfectly good ice maker.
- Follow the supply line behind the cabinet — You are looking for a kink against the wall and for a valve that was never fully reopened.
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.

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.
