The short answer
When a 4k7z10 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.
What you actually observe
- An empty bin and a dry, empty mould — No water is arriving, which points at the fill path rather than at the ice maker.
- Ice is still made but far more slowly than before — A partial restriction, not a failure.
- 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 4k7z10 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. Ice in the fill tube usually starts with a slightly low fill, which lets water sit in the tube instead of clearing it. This family is a single listing, so what is true of it is true of every unit carrying the badge.
- The bail arm or the ice level switch left off — A wire arm knocked up by a bag of frozen food tells the ice maker the bin is full, and it obediently stops. It is the first thing to check and it is free.
- A freezer that is not cold enough to harvest — An ice maker is a fair thermometer: it stops before the ice cream does.
- A kinked or shut supply line — A saddle valve half closed, or a line crushed against the wall when the cabinet was pushed back, starves the valve without leaking a drop.
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. Do this before any other step.
- 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. Never use a heat gun for this: it melts the tube and the liner behind it.
- 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. Leave a thermometer inside overnight so the reading is not chasing the last door opening.
- 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. Do it before the unit goes back.
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.
