The short answer
An ice maker on the AZF line that has stopped producing is usually being starved of water or being held off by its own shut-off arm, not broken. Three model numbers carry this family badge, and the matrix on this page is the list. The checks below run supply first and mechanism last, because the supply faults are the common ones and the only ones an owner can settle without a tool.
What the owner notices
- Hollow, undersized or cloudy cubes — Cubes that look the right shape and weigh almost nothing, because the tray was harvested before it filled.
- The shut-off arm or sensor is holding the cycle off — A wire arm lifted by a stray cube, or an optical sensor with frost across it, stops production with nothing actually broken.
- Water pooling under the bin or freezing in the fill tube — A partly frozen fill tube is the cause that gets worse cycle by cycle until it stops production entirely.
- NEAR MISS — the whole freezer is soft and the cabinet is warm — Soft ice cream and a bin that never fills together mean the freezer is the problem, not the ice maker.
Causes, most likely first on the AZF line
- Water supply: closed valve, kinked line or a spent filter — Ranked first on the AZF line: this family is a tight one — three model numbers under one badge and the supply path is outside the appliance entirely, so it fails the same way regardless of which model in the table you own.
- Shut-off arm lifted or the bin sensor blocked — Second because nothing has failed: a cube wedged under the arm or frost across the sensor window is a mechanism obeying an instruction, and it is the reason a great many working modules get replaced.
- Freezer not cold enough to complete a harvest — Third because production is gated on temperature. A freezer running a few degrees warm makes fewer and worse cubes long before anything in it thaws, so poor ice is an early warning about cooling.
- Fill valve, fill tube ice or the module itself — Fourth because these are the genuine failures — a valve that no longer opens, a module that no longer cycles — and they are worth reaching only when supply, mechanism state and temperature are all clean.
The check order on these models
- Press the door dispenser if the cabinet has one — Water there proves the supply, the shut-off valve and the filter are all passing, and no water ends the diagnosis outside the appliance.
- Check the shut-off arm is down and the sensor window is clear — Second because it is free and because a mechanism that has stopped itself looks exactly like a mechanism that has failed.
- Put a thermometer in the freezer overnight — A freezer holds food safely at 0 °F (−18 °C) or below; production is gated well before food is at risk, so a warm freezer explains poor ice with nothing else wrong.
- Look at the fill tube for ice and listen for the fill — Look at the fill tube and listen for the fill last, because both need the bin out and the module exposed.
Safety first
Safety
Switch the appliance off at the breaker or unplug it before working on the module; a capacitor can hold a charge after the power is off. Shut the water off at the household valve first, and keep a towel under the connection — the line stays pressurised after the appliance is dead. Do not chip ice out of the tray or the rake with anything metal.

Where owner work stops
Book a technician when the fill valve, the module or the freezer temperature turns out to be the answer, and book one immediately if the freezer is also failing to hold food. On the AZF line the practical boundary is whether the repair breaks a water joint — if it does, it is worth having done rather than attempted.
