The short answer for FFFDD models
Ice production on the FFFDD family depends on three things arriving together — water, cold and a working harvest cycle. The diagnosis is a matter of establishing which of the three is missing, and the mould tells you that in one look. Nothing below requires a panel off until the last step.
How the fault presents
- Production stopped outright rather than slowing down — A sudden stop points at water or at the arm; a gradual one points at temperature.
- Ice or water spilling over the front of the mould — An overfill, which points at the fill valve not shutting rather than at the mould.
- The mould holds water that never freezes solid — Water is arriving and the compartment is not cold enough to finish the job.
- NEAR MISS — no ice and the food in the freezer is soft — That is a cooling fault first. Fix the temperature and the ice usually returns on its own.
Causes in likelihood order on this model group
- Fill tube frozen shut — If a fill overshoots or the compartment runs very cold, the tube that delivers water can ice over, and every subsequent fill adds to the blockage rather than reaching the mould. First on this family because it needs nothing taken apart — on a cabinet this size it is a look and a listen, and excluding it costs less than five minutes.
- Air path to the compartment blocked by how it is packed — A compartment packed to the rear wall stops the cold air reaching the mould, so the machine can be running correctly and the ice maker still never see its release temperature. Second on this family: it produces the same complaint as the cause above it, so the two have to be separated before either is acted on.
- Bin jammed, or the arm held up by the ice already in it — The arm stops production when the bin is full, and a bridged clump of old ice holds it up while the bin is half empty. Third: common enough on refrigeration generally, but on a cabinet of this size the two above it account for most of what walks in the door.
Work through it in this order
- Water, cold, harvest — in that order — The three stages fail in different places, and checking them in sequence means you never test a stage that the previous one has already explained.
- Look for ice at the back of the compartment above the mould — A visible spike of ice is the fault. Clearing it is a temporary fix; what caused the overshoot is the real question.
- Clear the rear of the compartment and leave a gap — Anything hard against the back wall or a vent is a candidate before a part is suspected.
- Empty the bin completely and break up any bridged ice — Then let the arm fall and give the machine a few hours before judging it.
Before you touch anything
Safety
Power off before anything else — the plug out, or the breaker open. A capacitor can hold a charge after the power is off.

When to call a technician
Book a technician once the checks above come back clean, and book one straight away if any of three things is true: the compressor is hot and silent, the breaker will not hold, or there is oil at a joint. Those three each mean the fault has moved past the part of the machine an owner can reach.
