The short answer
On the FBFD 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.
- Ice production stopped after a filter change — Air in the line or a filter not seated home, and it clears once the line is purged.
- Cubes fused into a single block in the bin — Slow production and repeated partial melting, which points at compartment temperature.
- 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 FBFD
- Water supply: stop tap, line or a frozen fill tube — Ranked first on the FBFD family: these installations have a long supply run behind a built-in housing, where the stop tap is easy to leave part closed. That is a family-level property rather than a model-level one, which is why it leads here. 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 this family is a single build with fixed access points.
- 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 tall cabinet can be cold at one end and marginal at the other, so the ice module sees a different temperature from the food.
- Ice module, fill valve or the harvest mechanism — Fourth: the valve is at the back of the housing and is a service item on a built-in cabinet.
- Arm, switch or the ice-off setting — Last: a control lock or a setting left off during a service visit produces a perfect no-ice fault.
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.
- 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 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
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 supply at the stop tap before touching any fill line, and treat the sealed system as off limits: refrigerant work is licensed work.
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.
