The short answer
On the TMF family, a cabinet that has stopped making ice usually comes down to freezer not cold enough to finish a cycle. The quickest way to place it is to measure the freezer with a thermometer, not by feel. Three of the four causes below are owner-checkable in minutes; the last is where a service call starts.
What you observe
- Production is slow rather than stopped — A maker that keeps up in winter and falls behind in summer is being limited by the freezer temperature, not by the maker.
- The ice maker fills but the cubes never release — Water goes in on cycle and the tray stays full, which points at the harvest side rather than at the supply side.
- No water arrives at the tray at all — A dry tray with the maker cycling is a supply problem, and on an unplumbed cabinet it simply means the tray was not filled.
- NEAR MISS: no ice and the freezer is not properly cold — Fix the cooling first: nothing on this page will work while the freezer cannot hold temperature, and the cooling page covers it.
Causes, most likely first
- Freezer not cold enough to finish a cycle — An ice maker does not have its own cooling: it borrows the freezer, and a compartment that is a few degrees warm makes ice slowly, then in hollow cubes, then not at all.
- No water reaching the maker — Where the cabinet is plumbed, the supply chain is long and every link fails the same way: a valve left part closed after a move, a kinked line behind the cabinet, a filter never changed.
- Fill tube or tray frozen — It is common on cabinets where the freezer is very cold and the fill volume is small, which describes most of the models this page covers.
- Inlet valve weak or filter blocked — A valve that no longer opens fully gives a short fill, which is why hollow and undersized cubes so often come with a maker that is otherwise cycling correctly.
- Body: A few rows in the list carry a placeholder in place of a finish code, which is how the manufacturer's own list handles a cabinet offered in several colours. That order is the brand-generic order for this symptom, because nothing in how this line is built moves any of these causes past another.
Check in this order, and why
- Measure the freezer with a thermometer, not by feel — A freezer holds food safely at 0 degrees Fahrenheit, which is minus 18 degrees Celsius, or below. Above that the maker will struggle whatever else is right.
- Establish first whether this unit is plumbed or filled by hand — On a manual cabinet there is no supply fault to find.
- Look at the fill tube where it enters the tray — A finger of ice at the tube mouth, or a tray with a frozen crust across it, is the whole answer.
- Body: The order follows the ranking above rather than the layout of the cabinet: each check either confirms the cause above it or removes it, and they are arranged so that the free checks come before anything that needs the unit moved or a panel off. Access is the same across the models in the table, so the order holds for all of them.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before reaching into an ice maker mechanism. The harvest motor turns on a timer and does not announce itself, and the ejector arm has enough torque to trap a finger against the tray.

When to call a technician
Call when the freezer measures properly cold, the supply is proven, the fill tube is clear and the arm is free, and the maker still will not produce. That combination points at the module or the valve, both of which need the mechanism out and a meter on live terminals.
