The finding, first
An icemaker that has stopped producing is usually a water supply problem or a temperature problem, and on this family the supply side is checked first because it is reachable. The arm or the sensor that tells the mechanism the bin is full is the other frequent answer, and it costs nothing to check. All the first checks are owner work, and most of them need nothing but a look. Checking your listing against the table takes a moment and saves ordering against the wrong catalogue.
What you actually see
- Cubes are small but properly formed — A short fill rather than a blocked one. Suspect a restriction in the filter or a partially closed supply tap.
- Ice production stopped after the filter was changed — Air trapped in the line after a cartridge change. It usually clears after several dispenses, and it is not a fault.
- The bin is empty and the mechanism never cycles — No movement at all over a day. Points at supply, at the shut-off arm or at power to the module 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.
- 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.
- 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.
Ranked causes for these models
- Fill tube frozen — Top of the list here. The tube crosses from warm into cold and the last of each fill sits in that crossing; freeze it once and the mechanism harvests nothing from then on.
- Supply shut off, kinked or restricted — Second and entirely mundane. Valves get closed during other work and lines get pinched when a cabinet is pushed back, and neither event is remembered later.
- Freezer not cold enough to trigger a harvest — The mechanism has its own thermostat and will not eject until it is satisfied, so a compartment a few degrees warm gives you no ice rather than slow ice.
- 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.
What to check first, second, third
- 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.
- Force a harvest cycle and watch what the mechanism does — A mechanism that goes through its motions and delivers nothing has a supply problem, not a mechanical one.
- 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
Kill the supply before anything else happens: unplug it, or switch the breaker off. A capacitor can hold a charge long after the power has gone. Do not lever a frozen icemaker mechanism free.

When this stops being owner work
Stop at the point where the supply path is proven good. Everything after that is electrical testing inside a cold cabinet, which is service work on this roster.
