The short answer
On the Caf PVD family an ice maker that has stopped is usually a water-side fault rather than a failed module: a closed shutoff, a clogged filter, a frozen fill tube or a valve that no longer opens. One model tag covers this family in the matrix below, which keeps parts ordering simple and leaves the whole of the diagnosis to the symptom. A freezer holds food safely at 0 °F (−18 °C) or below, and the harvest cycle needs that same cold — a freezer running warm will leave a perfectly healthy ice maker idle.
What you can observe on these models
- Ice production stopped after a filter change — An unseated cartridge or an aftermarket filter that does not match the head restricts flow immediately.
- The bail arm is in the raised position — On arm-equipped models this is the off switch, and it is knocked up by a shifted bin more often than anyone expects.
- Water pools under the bin and refreezes — Overfill or a misaligned fill tube. It ends as a sheet of ice under the bin and a jammed auger.
- NEAR MISS — water leaking from the dispenser front — That is a water-leak fault rather than a production fault, and it belongs on the leak page.
Causes, most likely first on this family
- Water supply restricted — shutoff, filter or line pressure — First: it is upstream of everything and it produces both of the common presentations — no cubes at all and small hollow ones.
- Fill tube frozen or misaligned — Second: once a fill overshoots, each new fill freezes onto the last until the tube is a solid plug and no amount of module testing will help.
- Freezer temperature too warm to trigger harvest — Third — and the reason a slow ice maker is sometimes the first visible sign of a cooling problem.
- Water inlet valve solenoid or screen — Fourth: the valve is the one electrical part in the water path, and its inlet screen silts up long before the solenoid fails.
- Ice maker module, thermostat or ejector — Last on this platform, because everything above it is cheaper to test and more likely to be the cause.
Check in this order, and why
- Empty the bin completely and look underneath — A sheet of ice under the bin jams the auger and stops delivery while production continues normally.
- Confirm water reaches the mould on a forced fill — Water arriving and then sitting unfrozen moves the whole fault to temperature rather than supply.
- Check the fill tube alignment — A tube nudged out of line overfills the mould edge and builds the plug that stops the next cycle.
- Compare cube size over a full day — Hollow cubes that stay hollow confirm restricted flow; normal cubes that stop confirm the harvest side.
Before you open anything
Safety
Unplug before touching the module or its harness — a capacitor can hold a charge after the power is off. A freezer holds food safely at 0 °F (−18 °C) or below; if this job is going to take a while, move the frozen contents out first rather than working with the door propped. Keep water away from the dispenser electrics when clearing a chute.

When to call a technician
Call when the fault survives a filter change, a full bin clear-out and a fill-tube thaw, or when the freezer itself is not holding 0 °F (−18 °C). A warm freezer is a cooling repair and the ice maker is only the messenger. Anything that needs the valve replaced at the back of the cabinet, or the module harness unplugged, is a service call on these models.
