The short answer
A 4w5ij21 ice maker that has stopped is far more often a supply problem than a mechanical one. Where the brand-generic article opens with the module, this one opens with the fill tube, because on this platform that is the part that freezes first. Look in the mould before you order anything.
What you actually observe
- An empty bin and a dry, empty mould — Look into the mould rather than into the bin.
- Ice sitting in the mould that never drops — Water is arriving and the harvest is not happening.
- A single fused block instead of loose cubes — The bin has bridged, and the level arm is reading that as full.
- Ice is still made but far more slowly than before — Count cubes over a day rather than guessing.
Causes on the 4w5ij21 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. It is the most common ice fault on this family and it is owner-fixable. The short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- 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. Nothing is broken; the machine has simply been told not to bother.
- A clogged or wrongly seated water filter — A filter that is not fully home restricts the ice maker before it restricts the dispenser, because the mould gets the lower priority. If the dispenser is slow too, this is almost certainly it.
- A freezer that is not cold enough to harvest — An ice maker is a fair thermometer: it stops before the ice cream does. If yours stopped, check the compartment temperature before you touch the ice maker itself.
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.
- 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.
- 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. Never free a stuck mould or a jammed auger with a metal tool while the unit is powered: the harvest motor can start without warning and the mould heater is live. Shut the water off at the supply valve before you disturb any fitting.

When to call a technician
The line on these models is whether the fix is in front of the mould or behind it. Water supply, filter and bin are all reachable; the module, the thermostat and the heater are behind the ice maker and need it out. Call the same day if there is water running out of the freezer as well as no ice, because that is a valve stuck open.
