Short answer
On this platform an icemaker that has gone quiet is usually one that is not getting water: the stop valve, the supply line or the fill valve, none of which is inside the icemaker at all. What puts it first on this machine: it was installed flush and its clearances were set once, by whoever fitted it. The checks below follow that ranking, and the first need no tools.
What you observe
- The icemaker cycles and the tray stays empty — You hear the harvest and nothing arrives, which points at supply rather than at the maker.
- 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 — ice is made but tastes or smells wrong — That is a filter, a storage or a water-quality question rather than a production fault, and it belongs on a different page.
Causes, most likely first on this platform
- Water not reaching the icemaker — The whole ice path starts at a stop valve, a supply line and a fill valve, and any one of them stops the machine without a single fault in the icemaker itself. This is the most common reason ice stops and the cheapest to rule out. It leads on this platform: it was installed flush and its clearances were set once, by whoever fitted it.
- 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. Second on this platform, and the next thing to check.
- 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
- Confirm the supply stop valve is fully open and the line behind the cabinet is not kinked — It is the cheapest test of the top cause, and pulling a cabinet out to look costs minutes.
- 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
- Open the stop valve fully and straighten the supply line behind the cabinet — A line pinched by the cabinet being pushed back against the wall is the single commonest version of this fault.
About 15 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 Porter Charles 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.
