What this usually turns out to be
An ice maker that has stopped is usually a water problem rather than an ice-maker problem. Supply, fill valve and a frozen fill tube account for most of them, and all three can be investigated without tools. On the HC models the water path is common across the family, so the supply checks below hold for all of them even where the bin and the dispenser differ.
What the ice maker is doing
- The bin is empty and stays empty — Nothing at all is being produced, which points at water arriving or the ice maker being switched off rather than at a slow fault.
- Cubes are small, hollow or misshapen — Cubes that are half the size they should be, or hollow in the middle, mean water is arriving but not enough of it. That is a restriction, and it has its own short list.
- Ice has fused into one lump in the bin — Slow production, a warm freezer or repeated partial melting. The lump is the symptom of something upstream, not the fault itself.
- NEAR MISS — No ice and the whole cabinet has gone warm — If the whole cabinet has gone warm, the ice maker stopping is a consequence rather than the fault, and the cooling page is the one to read.
What is behind it, ranked
- The ice maker is switched off or its shut-off arm is held up — This also happens after any work in the freezer: the arm or the switch is knocked and nobody notices until the bin stays empty. It leads because it is free to check and, when it is the answer, free to fix. Where the brand-generic page starts with no water reaching the refrigerator, this family starts with the ice maker is switched off or its shut-off arm is held up — the access on these models makes it the cheaper first move.
- No water reaching the refrigerator — A closed house shut-off, a kinked line behind the machine or a supply valve never fully reopened after a move stops production instantly and completely.
- A frozen fill tube or a frozen supply line — Clearing the ice fixes it for a while; finding out why the water stalled long enough to freeze is what stops it returning.
- A clogged or wrongly seated water filter — A filter that is not fully seated, or an aftermarket one that does not quite fit, can throttle the supply the same way a clogged one does.
Check in this order, and why
- First — check the ice maker is actually switched on — Look at the control or the shut-off arm and make sure nothing in the freezer is holding it in the stop position. It is the cheapest check on the machine and it ends a surprising number of investigations.
- Second — confirm water is reaching the refrigerator at all — Prove water reaches the cabinet at all. No water anywhere means the fault is upstream of everything inside, and nothing internal is worth checking yet.
- Third — look for ice in the fill tube above the mould — Ice in the fill tube is both a cause and a symptom: it stops the fill now, and it formed because a fill stalled earlier.
- Fourth — check the age and seating of the water filter — Push the filter fully home and note its age. A filter near the end of its life throttles flow long before it stops it, which is why small cubes come before no cubes.
Power off before panels come off
Safety
Disconnect the refrigerator before working in the freezer compartment, and close the house water valve before disturbing any line. A supply line under pressure that is pinched or split behind a heavy cabinet floods a kitchen quickly, so check the line while the valve is shut rather than while it is not.
When to call a technician
Call when water is confirmed to be reaching the machine and ice still does not appear: at that point the candidates are the inlet valve, the fill system and the ice-maker module, and all three are tested live. Call sooner if you find water anywhere it should not be.
