The short answer for AFS models
When an Avanti AFS refrigerator stops making ice, the useful first question is whether water is arriving at all. Ice in the bin but fused into one lump is a completely different fault from an empty bin with a dry mould, and the two lead to different halves of this list.
What it looks like from the outside
- The mould is full of water but never harvests — Water arrives and the harvest cycle does not run.
- Production slowed gradually over months — The signature of a filter reaching the end of its life rather than of a sudden failure.
- A buzz twice a day with no water arriving — The fill valve is being asked to open against a closed or blocked supply.
- Ice cubes are hollow or half-sized — A partial fill, which means restricted flow rather than no flow.
- NEAR MISS — the whole cabinet is warm — Then this is a cooling failure and the ice is only the first symptom you noticed.
Likely causes on AFS, ordered
- Bail arm or shut-off sensor in the off position — Ranked first because it costs nothing to check and because a bin being pulled in and out is exactly what knocks it up.
- Freezer not cold enough to trigger harvest — The ice maker will not cycle until the mould reaches its harvest temperature, so a warm compartment stops production entirely.
- Supply line closed, kinked or frozen — A line pinched behind the cabinet when it was last pushed back is one of the most common causes we find on any brand.
- Low household water pressure — Where the valve cannot open against the available pressure, the symptom is identical to a failed valve.
The order that saves the most time
- The order, and why it is this one — Work down this list rather than starting where the fault seems loudest.
- Look into the fill tube with a torch for a plug of ice — A frozen tube blocks every fill after the first partial one.
- Put a thermometer in the freezer for an hour — A freezer holds food safely at zero degrees Fahrenheit or below, and an ice maker needs that cold to harvest.
- Pull the unit out and follow the supply line for a kink — Look particularly where the line passes behind the cabinet, which is where it gets pinched.
Before you take any panel off
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off, and the compressor circuit on a refrigerator is live whenever the plug is in. Leave the door switch wired exactly as it is: it cuts power to the evaporator fan for a reason, and defeating it puts a moving blade behind a panel you are reaching past.

When to call a technician
Once the coil is clean, the seals are proved and a full manual defrost has been tried, a fault that remains is a technician job. So is anything that needs a panel removed inside the cabinet.
