The short answer for this family
An ice maker that has stopped producing on the Alpicool KM family points first at a frozen fill tube. The order below is this family's own, and it is not the order the brand-generic article sets out. Of the causes listed here, all but one are owner-checkable, and a freezer section sitting above its ice-making temperature is the one worth ruling out immediately after the first.
What the owner sees
- Nothing has arrived for days and everything else works — Water and temperature are the two things to prove before anything else.
- The freezer feels colder than usual but no ice arrives — Cold alone does not make ice; water has to get there.
- The arm sits higher than it used to — A bin packed to the top holds the arm where it reads full.
- Ice has built outside the mould — A plug at the fill point puts water where it does not belong.
- Cubes taste stale or smell of the cabinet — Slow turnover rather than a fault, but it is often reported as one.
- A KM unit of a different size behaves identically — That is what a shared build looks like: the members of this ladder differ in scale rather than in arrangement.
- NEAR MISS — water on the floor rather than in the mould — A fill line letting go is the leak page.
Causes, most likely first on the KM family
- A frozen fill tube — It is the first thing to rule out on these models. Ice appears outside the mould rather than in it, which is the signature to look for.
- A freezer section sitting above its ice-making temperature — It follows the lead on these models. It is the cause that ties this page to the cooling page, and it is checked with a thermometer rather than a tool.
- A jammed or iced harvest arm — It comes after the two above it. The cycle completes and the ice stays where it was made.
- A sealed-system fault behind the freezer section — It ends the list. It is the least likely cause here and the only one with no owner-side check at all.
- Body: The brand-generic article on this symptom opens on water not reaching the ice maker. Here it does not: a frozen fill tube has moved above it, and water not reaching the ice maker has moved down the list. What moved it is the shape of this family's numbering rather than anything about the brand as a whole.
Check in this order, and why
- Warm the fill point and see whether one cycle recovers — A recovery that lasts a day and then stops is the plug returning.
- Put a thermometer in the freezer section and leave it — A section above its ice-making temperature fills the mould and never reaches release.
- Check for a single cube welded to the mould — One stuck cube stalls every cycle after it.
- Establish whether the section has ever reached its ice-making temperature since the fault began — A section that never gets there points behind the panel and behind a licence.
- Body: Confirm which of the two KM models you have first. The order below holds for both, but the access differs enough that guessing costs time.
Before any panel comes off
Safety
Power off first, every time. Unplug the appliance or switch off its breaker before removing a panel, since a capacitor can hold a charge after the power is off. Sheet-metal edges behind a panel cut, and a compressor housing stays hot long after a run. Gloves for the first, patience for the second. Refrigerant work is licensed work: nothing on the sealed side of this machine is owner work, whatever the symptom looks like from the front.

When to call a technician
The line here is drawn at the first check that cannot be made from outside the cabinet. Work down the checks above first; they cost minutes and they remove most of this list. Call once they have all come back clean, because what is left is a sealed-system fault behind the freezer section, and that is where the list stops being owner work. Two things end the owner-side list immediately: a burning smell, and oil anywhere outside the tubing. Both mean stop and call rather than continue.
