The short answer
On the BRUF family an ice fault is usually a water-supply or temperature problem rather than a failed ice module, and the split between the two decides everything. That reorders the brand-generic page, which starts at the module itself.
What you observe
- No ice at all and a dry mould — Water is not arriving: supply, valve or a frozen fill tube.
- Mould fills but the ice never releases — A temperature or harvest fault rather than a supply fault.
- Hollow, small or slow-forming cubes — Partial supply restriction, often a part-closed stop tap or a clogged filter.
- Ice tastes or smells wrong — An old filter or long-stored ice absorbing cabinet odours rather than a mechanical fault.
- NEAR MISS - the whole cabinet is warm — Fix the cooling fault first; ice production is the first thing to stop when a cabinet warms.
Causes, most likely first on BRUF
- Water supply: stop tap, line or a frozen fill tube — Ranked first on the BRUF family: the fill tube on this family runs through a cold zone and freezes closed before anything else fails. These codes share an evaporator arrangement and a defrost scheme, so a finding on one is worth assuming on the rest. What moves against the brand-generic order is lower down: freezer compartment not cold enough sits above ice module, fill valve or the harvest mechanism here, because these models share one layout, so its weak point shows across the whole family.
- Water filter overdue or restricting — Second: a filter past its life throttles the fill before it stops it, which is why hollow and undersized cubes arrive long before no cubes at all.
- Freezer compartment not cold enough — Third: a freezer holds food safely at 0 °F (−18 °C) or below, and a compartment above that makes soft ice or none.
- Ice module, fill valve or the harvest mechanism — Fourth: the module is a sealed assembly: it is diagnosed by elimination and replaced rather than repaired, which is why it sits below the supply questions.
- Arm, switch or the ice-off setting — Last: the cheapest thing to rule out and a real finding: a lifted arm stops production completely.
Check in this order, and why
- Check the arm or the ice-off setting first — It takes seconds and explains a total no-ice with nothing broken.
- Look at the mould: is it dry or full? — This single observation splits supply faults from freezing and harvest faults.
- Check the bin is fully home and the chute is clear — A bin not seated holds the arm up or blocks the chute and stops production entirely.
- Check the compartment temperature before blaming the module — A freezer holds food safely at 0 °F (−18 °C) or below; above that, no module will keep up.
Before you open anything
Safety
Isolate at the breaker before any panel comes off, and leave the sealed system alone entirely: refrigerant work is licensed work and the tools for it are not owner tools.
When to call a technician
Call once water is proven to reach the mould and the compartment is cold enough but no ice forms: what is left is the module or its harvest circuit, and neither is an owner part here.
