Before condemning the icemaker, establish whether it is being given water and whether it is being given cold. On this family one of those two is the answer far more often than not. The arm or the sensor that tells the mechanism the bin is full is the other frequent answer, and it costs nothing to check. Work the supply and the temperature first and the icemaker usually exonerates itself. Part numbers are left to the table above; the text stays with the method, which is what holds.
What is in the bin, and what it means
- A slab of ice in the bin rather than cubes — Melt and refreeze, which means the compartment temperature is swinging rather than holding.
- 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.
- 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.
- 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.
- NEAR MISS — water is leaking outside the cabinet — A supply leak is its own page and its own urgency; deal with the water before the ice.
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 undramatic. The valve behind the cabinet gets closed during other work or nudged when the unit is pushed back, and a kinked line does the same thing more slowly.
- 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 filter blocked or overdue — Restriction rather than blockage, and it shows in the shape of the cubes rather than in their absence. Also the last thing anyone thinks of.
- Water inlet valve or icemaker module failed — Bottom of the list. Both are genuine failures, both need testing rather than guessing, and that is where this page hands over.
Follow the water, in this order
- 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.
- Look at the fill tube where it enters the compartment — A plug of ice at the entry point is the commonest single finding on this page and it is visible from inside the freezer.
- 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.
Safety before diagnosis
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.

The line between a fix and a call
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.
