The short answer
This fault reads the same on every make, but it does not rank the same. On the BC models it is usually a frozen or kinked supply line. This line runs to enough models that the units in service span a wide range of ages, so the parts that wear sit ahead of the parts that fail from a design weakness.
What you observe
- Cubes are small, hollow or half-formed — Production has not stopped, it has been throttled — which points at water rather than at the maker.
- One fused slab in the bin instead of loose cubes — Usually with a story behind it: a power cut, a holiday, or a door left ajar.
- Frost has grown over the sensor window or the fill tube — The machine is reading the frost rather than the bin.
- NEAR MISS — no ice and the freezer is not properly cold — Then the cooling fault is the page to read first; the ice maker is a symptom of it.
Causes, most likely first on the BC line
- A frozen or kinked supply line — Ranked first here — it stops production completely and because the line is the part of the system most exposed to being pinched or chilled.
- A door or bin that is not sitting home — Second here — it is free to correct and because it explains a maker that works intermittently rather than not at all.
- A control module no longer timing the cycle — Third here — it is a component failure rather than a service condition, and the service conditions on this list are far more common.
- Body: A line this wide puts both old and recent units in front of you, and the ranking below favours the causes that come with age over the ones that come with a build. On this set the ordering survives the build unchanged, which is worth knowing before you spend time on the least likely of them.
Check in this order, and why
- Trace the supply line from the valve to the back of the cabinet — A tight bend behind a cabinet that was pushed back too far is the common find, and it needs no tools to see.
- Push the bin fully in and check the door shuts without resistance — A bin a centimetre proud holds the arm up, and a door held open by a shelf warms the compartment.
- Watch for any movement of the arm over several hours — A maker that never moves at all, in a freezer that is genuinely cold, points at what drives it.
- Body: Across a line this wide the access varies with the generation, so the order starts with checks that need no panel off at all, and only then moves to the ones that do. Work them in order: each one clears the cause it sits beside, and the next is only worth doing once the one before it is clean.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Shut the water off at the supply valve before touching any fitting, and never thaw a frozen line with a flame or a heat gun: the tubing is plastic and the cabinet behind it is not something you want to set alight.

When to call a technician
Call when the freezer is genuinely cold, the water supply is proven, the arm is free and the bin still fills with nothing — at that point the fault is inside the maker or its module. Call at once if you find water tracking along wiring or pooling under the cabinet, because that is an electrical question before it is an ice question.
