The short answer
On these models the icemaker is a passenger: it makes ice only when the freezer is cold enough and the water is arriving, so both of those get tested before the icemaker itself. A closed shut-off valve, a frozen fill tube and a freezer that is not cold enough account for most of it. All the first checks are owner work, and most of them need nothing but a look. Because the roster is one machine deep, the scope of this page is exactly the scope of that machine.
How it presents
- 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.
- 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.
- Ice is being made but far too slowly — Usually a compartment that is not quite cold enough, or a restricted supply that fills the tray part way.
- 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 — water is leaking outside the cabinet — A supply leak is its own page and its own urgency; deal with the water before the ice.
Causes, most likely first on this roster
- 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.
- Shut-off arm or bin sensor holding the mechanism off — The cheapest fault on the page. An arm lifted by stored food, or a beam broken by frost, reports a full bin to a mechanism looking at an empty one.
- Freezer not cold enough to trigger a harvest — The mechanism will not eject until its own thermostat is satisfied, so a compartment sitting a few degrees warm produces no ice at all rather than slower ice.
- 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.
- Put a thermometer in the freezer and leave it for a few hours — The mechanism will not harvest until it is cold enough, so a compartment that is only nearly cold makes no ice at all.
- 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.
Before you open anything
Safety
Isolation comes before inspection here. Unplug the appliance or trip its breaker, and assume every capacitor inside is still holding what it was holding. Do not lever a frozen icemaker mechanism free.

The line between a fix and a call
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.
