The short answer for RMS models
An ice maker on an Avanti RMS 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 this looks like in use
- The mould holds water but it never releases — Within the RMS family, full cavities that stay full mean freezing or ejection, not supply.
- The ice tastes of the freezer — On RMS models, ice absorbs odour from an uncovered load, and old ice absorbs more of it.
- The bin is empty and the mould is dry — On an RMS model, no water has arrived at all, which puts the fault in the supply chain rather than the mechanism.
- Production is slow rather than absent — On an RMS model, halved output usually means temperature, not a failed part.
- The ice tastes or smells wrong — On the RMS line, stale water in a line that has not been used for weeks, or an unlined bin absorbing cabinet odours.
- 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.
Ranked causes on the RMS line
- 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 water filter long past its life — A clogged filter starves the valve and gives you small hollow cubes on the way to none at all. On the RMS models below the ranking is the same.
- A bin of old ice that never turns over — Ranked here because the symptom reads as a fault and the cure is to throw the ice away.
- 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. The RMS models in the table below are no exception.
Check in this order, and why
- Look at the bin-full arm or sensor first — Looking at RMS models specifically, clear the bin, make sure the arm swings freely, and give it a cycle before going further.
- Give it a full day after any change before judging — Empty the bin, note the time and come back — a slow machine and a dead one look identical for the first hour.
- 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.
- Put a thermometer in the compartment overnight — A freezer holds food safely at 0 °F (−18 °C) or below, and a mould needs that to release.
Before you take any panel off
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.

When to hand it over
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.
