The short answer
On a True 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. Because the badge covers two very different product families, the first job on this page is to work out which kind of cabinet you have, and the ranking says how.
What you are actually seeing
- You hear the maker cycle but nothing arrives — Water is not reaching the mould, so the mechanism is working and the supply is not.
- A sheet of ice is forming under the bin — Water is arriving where it should not, which belongs on the leak page.
- Cubes are small, hollow or misshapen — The mould is filling partially, which is a restriction rather than a failure.
- NEAR MISS — the dispenser gives no water either — Then the fault is common to both and it is upstream: supply, filter or valve, not the ice maker.
Causes, most likely first on this refrigerator
- A restricted filter starving the fill valve — Ranked first on True: a filter on a kitchen supply loads up quickly, and once it restricts, ice is the first thing to suffer because it is the lowest-priority draw. On this one, remember that the badge spans commercial and residential cabinets, so establish which one you have before anything else.
- Water is not reaching the cabinet — a closed valve, a kinked line or a frozen supply — Second: a kitchen supply is shared with other equipment, so pressure can be fine at the sink and marginal at the cabinet.
- A fill valve that no longer opens reliably — Third: it needs the supply and the filter cleared before it can be blamed, and it is the first part on this list that is not an owner job.
- Ice maker module, motor or mould heater — 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 — follow the water line from the shut-off to the back of the cabinet — Every fault downstream of this looks identical, so clearing the supply first saves the rest of the list.
- 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
- Check the shut-off is open and the line is not kinked or crushed — Trace the line from the valve to the cabinet. Straighten any tight bend and make sure the cabinet is not standing on it.
Tools: torchAbout 10 min
- STOP here if the next thing to check is behind a fixed panel — Everything above can be done without tools on live parts. Past this point it is a technician job.
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.

What this page does not cover
This page is written for the True 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.
