The short answer
For the Alpicool MT family, an ice maker that has stopped producing is usually a jammed or iced harvest arm rather than anything deeper in the machine. The brand-generic page opens elsewhere, and the ranking below says which cause moved and what moved it. Most of what follows can be settled without opening anything; only the last item is a service call.
What you observe
- The arm sits higher than it used to — A bin packed to the top holds the arm where it reads full.
- Production fell off gradually rather than stopping — Anything gradual points at flow, not at a switch.
- A buzzing every few hours with no fill — The valve is being asked and is not answering.
- The freezer feels colder than usual but no ice arrives — Cold alone does not make ice; water has to get there.
- Cubes taste stale or smell of the cabinet — Slow turnover rather than a fault, but it is often reported as one.
- A MT 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 — the whole cabinet is warm — Fix the cooling first; ice is the last thing a struggling unit gives up.
Causes, most likely first on the MT family
- A jammed or iced harvest arm — It leads here. The cycle completes and the ice stays where it was made.
- A failed fill valve — It sits behind the lead here. It often fails partly rather than completely, so cubes come out small before they stop coming.
- A kinked or blocked supply line — It is third on this family. It is found by looking rather than by testing, and it is the cheapest thing on this list to put right.
- A sealed-system fault behind the freezer section — Last on this family. When water, temperature and the module are all proved good, what remains is behind a panel and behind a licence.
- Body: The brand-generic article on this symptom opens on water not reaching the ice maker. Here it does not: a jammed or iced harvest arm has moved above it, and water not reaching the ice maker has moved down the list. What moved it is how this family is laid out across the entries in its own table.
Check in this order, and why
- Check for a single cube welded to the mould — One stuck cube stalls every cycle after it.
- Listen for a buzz at fill time with no water arriving — The valve being asked and not answering is audible without any tool.
- Check the line where it bends rather than where it connects — Crush damage is found by looking, and it is the cheapest thing here to put right.
- 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 MT models you have first. The order below holds for both, but the access differs enough that guessing costs time.
Before you open anything
Safety
Before a panel comes off, isolate the unit at the plug or at the breaker. A capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts the fan when the door opens for a reason, and defeating it puts a hand near a blade that is still able to turn. 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
What separates the two halves of this list is access, not difficulty. 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 the only item on this page that cannot be judged from outside the cabinet. Skip the rest of the list and call if the unit is tripping protection repeatedly. A circuit that keeps opening is telling you something the checks above cannot.
