The short answer
On a KitchenAid refrigerator, an ice maker producing nothing usually comes down to a frozen fill tube rather than anything deeper in the machine: a fill that arrives too slowly freezes at the point where the tube enters the compartment, and production stops with nothing actually broken. That keeps it an owner check first, not a service call. Start here: identify whether this is a built-in or a freestanding cabinet before anything else, because KitchenAid's two lines share a badge and almost no service procedure.
What you are seeing
- An empty bin after a full day with the maker switched on
- Cubes frozen in the mould part way through an ejection
- Small or hollow cubes that were full size before
- Not this fault: A warm freezer as well as no ice, which is a cooling fault first
- Not this fault: Water on the floor with the ice fault, which is a leak and takes priority
- Body: KitchenAid builds this refrigerator as a built-in or counter-depth cabinet on the family platform, with a fill-tube heater on the built-in ice systems, a control board behind a rear access panel and a separate dispenser interface. That architecture decides which of these you see first.
- Also check note: If these fit better, the fault is a different one.
Likely causes, in order
- A frozen fill tube — Why this rank: KitchenAid's built-in ice systems carry a heater on the fill tube, so a fill-tube plug on this platform means the heater circuit rather than just a slow fill.
- The bail arm or ice-level sensor — Why this rank: An arm knocked up, or a beam sensor blocked by a bag, tells the maker the bin is full and it stops.
- An overdue water filter — Why this rank: KitchenAid's filter head bypasses when the cartridge is not seated, and a partly seated cartridge starves the maker while the dispenser still runs.
- The water fill valve — Why this rank: The KitchenAid fill valve is a dual solenoid, so the dispenser can work perfectly while the maker gets nothing.
- The ice maker module — Why this rank: The KitchenAid maker module is a sealed assembly with its own thermostat.
- Body: Ranked for a KitchenAid refrigerator specifically.
What to check, in order
- Body: The order follows the ranking, and the ranking follows the platform. First: look at the tube entry for a plug of ice. It goes first because kitchenAid's built-in ice systems carry a heater on the fill tube, so a fill-tube plug on this platform means the heater circuit rather than just a slow fill. Second: check the arm is down and nothing is in the beam path. With the first check clean, this is what the KitchenAid platform makes next most likely. Third: time a large glass from the dispenser. Only after those three is it worth reaching for the water fill valve: it costs more to get at, and it does not explain the first three coming back clean.
Checks you can make
- Pull the water filter, check that its cartridge seats fully and run a large glass from the dispenser. A dispenser that runs slowly or not at all with a fresh filter is a supply problem, not a maker problem. — Tools: measuring jug — Time: about ten minutes
- Empty the ice bin completely, write down the time, and look again after a full day. Judging production from a part-full bin is the most common reason people replace a working maker. — Tools: pen and paper — Time: a day of waiting
- Read the model badge inside the fresh-food compartment and note whether the cabinet is built-in or freestanding before ordering any part. The two lines share almost nothing. — Tools: flashlight — Time: about five minutes
- Look at the bail arm or the ice-level sensor in the compartment. An arm knocked up by a bag of ice, or a beam blocked by a package, tells the maker the bin is full and it simply stops. — Tools: flashlight — Time: about five minutes
- Body: Stop at the first step that would need a meter on live terminals or a sealed assembly opened.
Before you open anything
Safety
Switch the machine off at its breaker, or unplug it, before removing any panel. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Work with the floor dry and stand on something dry. Water on the floor is part of the electrical hazard, not separate from it.
When to call
The line is not difficulty, it is what the next step costs and risks. Call when: the fill is proven good and the mould still never fills the module stalls part way through an ejection with the fill working

What this page omits
This is generalized information: it ranks causes for the KitchenAid refrigerator range as one platform, not for a single model. Where a page exists for your specific model it is the more specific one and takes precedence over this. The narrower pages below cover the other presentations of this symptom.
