The short answer
On a True Residential refrigerator, an ice maker that has stopped is a water problem far more often than it is an ice maker problem. Work from the tap towards the mould: supply, fill, freeze, harvest. A built-in column is trapped in joinery, so its airflow path runs through a grille someone else installed, and that grille leads the ranking.
What you are actually seeing
- Cubes have frozen into one block in the bin — Slow use plus a partial thaw, often after a door left ajar.
- You hear the maker cycle but nothing arrives — Water is not reaching the mould, so the mechanism is working and the supply is not.
- The bin is empty and stays empty — No cycle is completing at all.
- NEAR MISS — food in the freezer is soft — The freezer is not holding temperature and cooling failure is the page you want.
Causes, most likely first on this refrigerator
- A restricted filter starving the fill valve — Ranked first on True Residential: a built-in column filters everything it dispenses, so the filter is in the path of both the dispenser and the ice maker and restricts both together. On this one, remember that it is a built-in column in joinery, so its air path belongs to the cabinetry as much as to the unit.
- Fill tube frozen shut, so each fill freezes before it arrives — Second: it is the classic cascade: something slows the fill, the slow fill freezes on the way in, and now the blockage is ice rather than the original fault.
- The ice maker has been switched off, by hand or by a bin that is jammed full — Third: it costs nothing to rule out, and a bail arm knocked up by a bag of frozen peas is the single commonest reason a working ice maker makes nothing.
- The ice maker mechanism itself — Ranked last here, deliberately: it is the part everybody replaces first and the part that is actually at fault least often, which is the whole reason for this order.
Check in this order, and why
- First — note when the filter was last changed, and how the dispenser flows — A weak dispenser and no ice together point at one restriction feeding both.
- Then — look into the fill tube at the back of the ice maker for a plug of ice — Finding ice here tells you the original fault was upstream, which is why the supply and filter come first.
- Third — look at the bail arm or the level sensor path — An arm held up, or a sensor eye blocked by a box, stops production with nothing broken.
- Only then — only once supply, filter, fill tube and freezer temperature are all clean — Everything above it produces the same nothing-in-the-bin, and all of it is cheaper, which is why it comes after everything above it.
What an owner can safely check
- Change the filter, then run water through the dispenser until it runs clear and steady — A new filter holds air. Purge it until the flow is smooth before you judge the ice maker.
About 15 min
- Lower the bail arm and clear the sensor path — Move anything leaning against the arm or blocking the level sensor, then leave it a full day before judging.
About 5 min
- STOP before testing anything electrical with the power on — The checks above are all cold checks. Anything that needs power applied is where an owner check ends.
Before you open anything
Safety
Switch the ice maker off before you put a hand near the mould — a harvest cycle starts on a timer and the ejector moves without warning. Unplug the cabinet before removing any panel. Never clear a frozen fill tube with a heat gun, a hair dryer on high or a screwdriver: warm water on a cloth is the only safe way, and the plastic behind that tube melts long before ice does.
When it stops being an owner job
Call once supply, filter, fill tube and freezer temperature are all clean and the bin is still empty — at that point the fault is in the valve or the module and both need the panel off. Call sooner if water is arriving somewhere it should not, if the cabinet is also failing to hold temperature, or if the fill tube refreezes within a day of being cleared, which means the original restriction is still there.

This page is written for the True Residential refrigerator as a class, not for one family or one model line. Where a family-specific page exists for your unit it is linked above and it is the more specific answer. Deliberately not here: part numbers, wiring colours, torque figures and any measured value, all of which differ by family.
