What this usually is
The icemaker on this platform is a simple mechanism with three external dependencies, and it is nearly always one of the dependencies that has failed. A closed shut-off valve, a frozen fill tube and a freezer that is not cold enough account for most of it. The mechanism itself is the last thing to suspect, not the first. With a pair of listings on the roster, the page treats them as one machine because for this fault they are.
What you actually see
- Water on the floor of the freezer under the icemaker — Overfill, or a fill tube that is thawing and dripping. Either way the supply side is where to look.
- The mechanism cycles and dumps nothing — It is being told to harvest and has nothing to harvest, which is the signature of a frozen or closed supply.
- Ice tastes or smells wrong — A filter at the end of its life, or ice that has been in the bin long enough to absorb everything else in the freezer.
- The mechanism runs on a cycle but the bin never fills — Production far slower than consumption, which points at the compartment temperature rather than at the mechanism.
- A slab of ice in the bin rather than cubes — Melt and refreeze, which means the compartment temperature is swinging rather than holding.
- NEAR MISS — the whole freezer is soft — Then the icemaker is a symptom and the cooling failure page for this family is the one you want.
Causes, most likely first on this roster
- Fill tube frozen — First on this roster. The tube crosses from a warm space into a cold one and any drip left behind after a fill can freeze there, which plugs the line solid and leaves the mechanism harvesting nothing.
- Shut-off arm or bin sensor holding the mechanism off — The cheapest fault here. An arm lifted by a bag of frozen peas, or a sensor beam interrupted by frost, tells the icemaker the bin is full when it is empty.
- Water filter blocked or overdue — A filter at the end of its life restricts flow enough to part-fill the tray, which is where hollow cubes come from. It also tends to be the last thing anyone thinks of.
- Water inlet valve or icemaker module failed — Last on the list. Both are real failures and both need testing rather than guessing, which is where this page hands over.
The diagnostic order for this family
- Check the shut-off arm is down, or the bin sensor is clear — An arm held up by a stored bag stops production completely and takes a second to rule out.
- Trace the supply line to the valve behind the cabinet — Look for a closed tap and for a kink where the cabinet was pushed back. Last on the list because it means moving the machine.
- Time how long the dispenser takes to fill a cup — A crude flow measurement, and the cheapest way to see a restriction before it reaches the tray.
What to do before the panel comes off
Safety
Take the power away first — at the plug, or at the breaker where there is no reachable plug — and treat any capacitor as charged until proven otherwise. The supply line behind the cabinet is under mains pressure.
Models in the J family — Every listing below is in scope. The table is the boundary of this page's generalization.

When this stops being owner work
The owner line on this family is the fill tube. Thawing it, clearing the arm, changing the filter and opening the supply tap are all owner jobs.
