The short answer
The AWCA roster spans several capacity cores rather than one, so the cabinets it covers differ in how far air and meltwater have to travel inside them, and the capacity core carried in each code is what separates one entry on it from the next. An ice maker in this roster that has stopped producing has usually lost its water or its temperature, not its motor. The mechanism only runs when the compartment is cold enough and the fill actually arrives, so those two are what the diagnosis is about.
What you observe on these models
- Production that stopped after the cabinet was moved — The supply line or the fill tube has shifted. Timing that specific points away from the mechanism entirely.
- No ice at all and a dry mould — Nothing is arriving. The diagnosis is the water route: the shut-off arm, the supply, the valve or a frozen fill tube.
- A mould with water in it that never freezes — Water is arriving and the compartment is not cold enough to complete a cycle. That makes it a temperature fault wearing an ice-maker costume.
- Hollow, small or misshapen cubes — A partial fill. Low supply pressure, a restricted filter or a valve that is not opening fully all produce the same shrunken cube.
Causes, most likely first on the AWCA line
- The compartment is not cold enough to complete a cycle — Ranked first on this roster: the mechanism will not harvest until the mould reaches its release temperature, so a compartment that has drifted warm stops production while looking otherwise healthy.
- Shut-off arm raised or bin sensor blocked — It ranks second here because it needs no tool, takes seconds, and is the most common reason a working ice maker produces nothing.
- Supply line, shut-off valve or house pressure — Ranked third on this roster: nothing arrives if the line is kinked behind the cabinet, the shut-off was closed after other work, or the supply pressure is below what the fill valve needs to open properly.
- Ice maker module or mould heater failed — Ranked last on this roster: the module drives the harvest and the mould heater releases the ice, so a failure there produces frozen cubes that never leave the mould.
- Body: Where this ranking departs from the brand-generic order is the compartment is not cold enough to complete a cycle, which moves up on the AWCA line because the roster spans several capacity cores, and a longer cabinet has a longer air path and a longer run to its drain.
Check in this order, and why
- Look into the mould for standing water — Water present and not frozen means the temperature is the problem. Work the cooling fault instead.
- Look at the arm or sensor path before anything else — Lower a raised arm, clear anything sitting in front of a sensor, and give it a few hours.
- Trace the line from the shut-off to the cabinet — Look for a kink, a closed valve and a line that has been trapped behind the cabinet. Pull the cabinet out to check properly.
- Have the module tested rather than replaced on suspicion — Cubes fully formed and never released point here, but every cause above it is cheaper and should be cleared first.
Before you open anything
Safety
Switch off at the breaker before any panel comes off and before putting a hand into the ice maker housing, because the harvest mechanism moves under power and does not warn you. Close the household shut-off before touching a supply fitting; a line under pressure behind a heavy cabinet is difficult to stop once it starts. Use warm water on an ice plug, never a tool, and keep water away from the supply cord throughout.

When to call a technician
Call when cubes form fully and never release, because that pattern points at the harvest side and nothing an owner can reach will change it. Call immediately if you find water anywhere around the supply fitting, and close the household shut-off before you do: a leaking supply behind a heavy cabinet does far more damage than a week without ice.
