The short answer
Not every model in this family ships with an ice maker, so the first question is whether yours has one and whether it is switched on — the bail arm or the on-screen setting stops production silently. After that the order is supply, then temperature, then the module itself. three model numbers share the BCFK designation. They are in the table below, and the trailing letters that separate them are finish and trim codes rather than different mechanisms — the fault below behaves the same across the list.
What you actually observe
- Maker fills but never harvests — The mould is not reaching harvest temperature, or the module has failed. Compartment temperature first.
- Nothing happens at all and no water arrives — Supply side: shut-off valve, the line, the inlet valve, or a frozen fill tube.
- Ice production stopped after the filter was changed — An unseated cartridge or an air lock. Common, immediate and free to correct.
- Bail arm is up or the setting is off — The most-missed cause there is, and it takes seconds to rule out.
- NEAR MISS — plenty of ice but the cabinet is warm — Then the cooling page is the right one; the maker working proves the cold side is not the problem.
Most likely first
- Filter and flow — Ranked first where the cubes are small or hollow rather than absent: an overdue cartridge, an unseated one after a change, or air still in the line.
- Freezing in the fill path — Second, and visible with a torch: a plug of ice at the end of the fill tube stops the fill without anything having failed.
- Temperature and airflow in the compartment — Third. Frost across the compartment, a blocked vent or a door seal losing the argument all reduce the maker to a spectator.
- Valve and module — Last. An inlet valve that opens partially gives poor ice; one that does not open gives none. Both are diagnosed with a meter behind a panel.
Check in this order, and why that order
- Start at the tap, end at the mould — Shut-off, line, valve, filter, fill tube, mould. Working along that path in order finds the fault without guessing.
- Give a new or freshly serviced unit time — A maker that has just been connected or a cabinet that has just been defrosted needs a full cycle or two before it is judged.
- Feel the mould after a cycle — A mould full of water that never freezes points at the compartment; a dry mould points at the fill.
- Stop at the module — Testing a module means working on a live appliance behind a panel, which is a service call on this cabinet class.
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. Do not thaw a frozen fill tube with a heat gun, a hair dryer on full or boiling water poured into the compartment: the plastic distorts, and a distorted tube leaks into the cabinet afterwards. If you close a household shut-off valve to work on the supply, open it again slowly and check the joint for weeping before pushing the cabinet back.

Where the owner line is on these models
The owner line on these models runs from the household shut-off to the fill tube. The arm, the setting, the filter, a kinked line, a frozen tube and the compartment temperature are all yours, and together they explain most makers that stop. Call when water is proven to reach the cabinet, the compartment is genuinely cold, and the maker still fills without harvesting or harvests without filling — that is the module, its thermostat or its motor, and diagnosing them means working on a live appliance behind a panel. Whichever of the three models in the table above you have, quote the full number from the rating plate when you call — the family letters alone will not get the right part.
