The WBC answer in short
An ice maker on an Avanti WBC refrigerator that has stopped producing is a water-supply problem far more often than a mechanism problem. The valve, the line and the freezing temperature all have to be right before the mould can cycle, and any one of the three will leave you with an empty bin and a machine that otherwise looks healthy.
What the owner sees
- Cubes have fused into one lump in the bin — For WBC models, clumping tells you the bin is warming between cycles.
- The ice tastes of the freezer — On a WBC model, empty the bin and let it make fresh: taste is not a mechanical fault.
- The bin is empty and the mould is dry — On a WBC model, a dry mould is the clearest possible pointer: look at the valve, the line and the pressure.
- Production is slow rather than absent — On WBC models in particular, a compartment slightly too warm slows every cycle without stopping any of them.
- Ice cubes are small, hollow or misshapen — Within the WBC family, hollow cubes are the classic low-flow signature and they appear long before production stops.
- NEAR MISS — nothing in the cabinet is properly cold — Then ice is the least of it: the cooling-failure page is the right place, and ice will return when cold does.
What actually fails on WBC models, in order
- A closed, kinked or frozen water supply — It leads because the machine cannot make ice out of nothing, and the whole supply chain is checkable without tools.
- A compartment that is not cold enough to freeze — Ranked high because a freezer holds food safely at 0 °F (−18 °C) or below, and an ice mould needs that same cold to cycle at a useful rate. That is the position it takes on this family.
- The bin-full arm or sensor stuck in the full position — This one is high value for how cheap it is: look before you diagnose anything else.
- A failed ice-maker module or its wiring — Last: the module itself is the least likely link in the chain and the only one that is a parts-and-labour job. It sits there for WBC models too.
Work through these in order
- Look at the bin-full arm or sensor first — Across the WBC line, anything resting against it reads as a full bin and stops production dead, at zero cost to check.
- Follow the fill line from the machine to the valve — Check the line is not pinched where the machine was pushed back, and that the tap is fully open.
- Empty the bin completely and let it refill — On the WBC models listed below, it resets the shut-off arm and tells you whether the maker works at all.
- Listen for the fill buzz after a harvest — A short buzz means water is being asked for; silence means the maker is not calling for it.
Before you take any panel off
Safety
Isolate the machine and close the water valve before touching the fill line; a capacitor can hold a charge after the power is off. Warm air thaws an ice plug safely, boiling water does not — it splits plastic tubing and turns a free fix into a flood. Leave every switch and interlock exactly as found.

Where the owner line falls
The owner line here is the bin, the arm, the supply and the temperature. Everything past it is a part in the maker itself, tested with a meter behind a panel. Call sooner if you can see water anywhere near the electrics, because that is an electrical matter rather than an ice one.
