The short answer for RMX models
When an Avanti RMX refrigerator stops making ice, work the chain in order: is water arriving, is the compartment cold enough to freeze it, and is the harvest mechanism cycling. On these machines the first two links account for most cases, and both are checkable without opening anything up.
What this looks like in use
- Ice cubes are small, hollow or misshapen — Across the RMX line, hollow cubes are the classic low-flow signature and they appear long before production stops.
- The mould fills but the cubes come out hollow or small — Within the RMX family, hollow cubes are the classic sign of a compartment that is not cold enough for long enough.
- Production is slow rather than absent — On this family, halved output usually means temperature, not a failed part.
- The ice tastes of the freezer — Within the RMX family, empty the bin and let it make fresh: taste is not a mechanical fault.
- You can hear the fill valve buzz but no water comes — Within the RMX family, a buzzing valve with a dry mould is a supply fault almost every time.
- 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 RMX 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 blocked or failing water inlet valve — Screens silt up and solenoids weaken; both produce a partial fill first and no fill later. It keeps that place on the RMX line.
- A bin of old ice that never turns over — Ice sublimates and shrinks in a dry compartment, so a bin nobody empties ends up full of small, fused, stale cubes.
- 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 is ranked the same way on every RMX model.
Check in this order, and why
- Look at the bin-full arm or sensor first — For the RMX line, clear the bin, make sure the arm swings freely, and give it a cycle before going further.
- Follow the fill line from the machine to the valve — Kinks behind the cabinet and a half-open saddle valve are the two commonest faults on the whole page.
- Check the age of the water filter, if the machine has one — On RMX models in particular, a filter past its life is the cheapest cause of small, hollow cubes and then of none.
- Empty the bin completely and let it refill — In the RMX family, do this before anything else: a fused lump imitates several different faults.
Before you begin
Safety
Unplug the refrigerator or switch off its breaker before reaching into the maker or taking a panel off — a capacitor can hold a charge after the power is off, and the harvest mechanism can move while your fingers are in the mould. Never force a frozen mould with a metal tool: the heater and the sensor are in there and both are easy to destroy.

Where the owner line falls
Hand it over once the arm, the supply, the filter and the temperature are all confirmed good. At that point the remaining candidates are the inlet valve, the module and its harness — all behind panels, all with water and electricity in the same small space. Call sooner if you find any sign of water where it should not be.
