The short answer
On a True Refrigeration 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 cabinet in a working kitchen is opened many times an hour by people who are not thinking about the door, so load and sealing outrank component failure.
What you are actually seeing
- Cubes are small, hollow or misshapen — The mould is filling partially, which is a restriction rather than a failure.
- Ice is produced but tastes or smells wrong — That is a filter and storage question, not a production one.
- You hear the maker cycle but nothing arrives — Water is not reaching the mould, so the mechanism is working and the supply is not.
- 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
- Water filter clogged, or a new filter never purged — Ranked first on True Refrigeration: 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 door is opened constantly by people carrying things, so load discipline outranks parts.
- Freezer temperature above the point at which the mould will release — Second: the mould has to reach its release temperature before a cycle starts, so a freezer that is merely cool makes no ice at all rather than making it slowly.
- Inlet valve failing, or the pressure at the valve is too low to open it — 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.
- The ice maker mechanism itself — Bottom of the list, which is the useful part: 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 — check whether ice cream in the freezer is firm or soft — Soft ice cream means the freezer is the fault and the ice maker is only the messenger.
- 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
- Judge the freezer by its contents before blaming the ice maker — A freezer holds food safely at 0 °F (-18 °C) or below. Soft contents mean you are on the wrong page and cooling failure is the one you want.
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 Refrigeration 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.
