The short answer
On the G 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 G
- Water supply: stop tap, line or a frozen fill tube — Ranked first on the G family: the fill tube on this family runs through a cold zone and freezes closed before anything else fails. The order below follows the air path rather than the refrigeration circuit, which is a family property and not a model one. 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 on this family and is replaced rather than repaired.
- Arm, switch or the ice-off setting — Last: last only because it is free to check: a raised arm or an off setting produces a total no-ice with nothing broken at all.
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.
- Purge several litres through the dispenser where one is fitted — It clears air after a filter change, which is the commonest post-service complaint.
- 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
Kill the power at the breaker first, shut the water at the stop tap before touching a fill line, and call at once if you see oil at the compressor or smell burning.
When to call a technician
Call at once if water is leaking while you investigate. A weeping fill valve turns an ice fault into a floor problem, and the supply should be shut before anything else.
