What this usually means here
On this platform the icemaker is usually innocent: the freezer is running a few degrees warm, the mould never reaches harvest temperature, and production slows to nothing. What puts it first on this machine: the glass front is the most exposed surface on the cabinet. The checks below follow that ranking, and the first need no tools.
What you observe
- Ice production slowed over weeks rather than stopping one day — A gradual decline is a temperature story; an abrupt stop is usually a water or electrical one.
- Ice stopped abruptly, with no change in anything else the cabinet does — Nothing else about the machine changed on the day it stopped.
- Hollow, partial or undersized cubes, or a sheet of ice under the icemaker — Water arriving where the fill tube ends rather than in the mould.
- NEAR MISS — cubes fuse into a single block in the bin — That is slow usage and a partial thaw cycle, not a production failure; the machine is working and the bin is not being emptied.
Causes, most likely first on this platform
- A freezer that is not cold enough to freeze a harvest — An icemaker will not release a batch until the mould reaches its harvest temperature. A freezer sitting a few degrees warm makes ice slowly or stops entirely, and the owner reads that as an icemaker fault when it is a cooling fault. First, and not narrowly — the glass front is the most exposed surface on the cabinet.
- The icemaker switched off at its own control — Every icemaker has a shut-off — a wire arm, a switch or a menu setting — and it is knocked into the off position by a hand reaching past it or by a bag of ice pressed against it more often than any part fails. It ranks second here: it runs a long duty cycle in a warm, busy room.
- A frozen fill tube or fill cup — The fill tube delivers a measured shot of water into the mould. If the last fill leaves a dribble behind, it freezes there, and the next fill backs up against a plug of ice and spills instead of filling. Third rather than higher, because the two causes above it are commoner.
Check in this order, and why
- Check whether the freezer is actually holding its temperature — A freezer holds food safely at 0 °F (-18 °C) or below; a mould in a compartment warmer than that will not harvest, and no icemaker part will change that.
- Look at the shut-off arm or switch and clear anything resting against it — It is first because it is free, instant, and the commonest single answer on any platform.
- Look at the fill tube mouth above the icemaker for a plug of ice — It confirms the second cause on sight and takes as long as opening the freezer door.
What an owner can safely check
- Verify the freezer setting and give the cabinet a day at its normal setting — Ice comes back on its own once the compartment holds temperature, with nothing replaced.
Tools: thermometerAbout 20 min
- STOP at the first step needing a meter on live terminals or a sealed panel off — That is where owner checks end. Write down what came back clean: a technician who knows that spends the visit fixing rather than repeating it.
Before you open anything
Safety
Switch the cabinet off at the breaker before removing the icemaker or any panel behind it — the module and the fill valve carry line voltage. Shut the supply stop valve before touching any water fitting. Never thaw a fill tube with a flame or a heat gun against plastic: warm water and time are the tools for that job.
When to call a technician
Call when the fault is on the fill valve, the icemaker module or the water line inside the cabinet wall, and call sooner if you find water where it should not be — a leaking fill valve floods slowly and quietly. The other clear line is a freezer that is not actually cold enough to make ice, which is a cooling fault first and an icemaker fault only afterwards.

What this page does not cover
This is generalized information for the Pulmuone refrigerator as a class, not for one family or model line. Where a family- or model-specific page exists for your unit it is the more specific answer, it is linked among the pages above, and it supersedes this one wherever the two differ. Not covered here: part numbers, harness colours, fill-valve ratings and the disassembly order, all of which differ by family and belong on the page for that family.
