The short answer
On the KM line an empty ice bin is more often a temperature or a routine problem than a broken mechanism: measure the compartment before anything else, because ice needs a properly freezing space and cold is not the same thing. The checks below settle most cases without a tool.
What the owner actually sees
- No ice at all over a full undisturbed day — The compartment is cold to the hand but the bin stays empty.
- Cubes that are hollow, small or misshapen — Ice forms but never completes, which points at temperature or at water rather than at the mechanism.
- A solid slab instead of separate cubes — Ice that partly melted and refroze, bonded into one block that then stops production.
- NEAR MISS - nothing in the cabinet is cold either — That is a cooling failure rather than an ice fault, and the not-cooling page for this line covers it properly.
What it usually turns out to be, in order
- The compartment never reaching freezing temperatures — Ranked first on this line: ice needs a compartment that is properly below freezing, not merely cold. A freezer holds food safely at 0 degrees Fahrenheit, which is minus 18 Celsius, or below, and a compartment sitting a few degrees under freezing will make ice slowly, hollow or not at all.
- Frost insulating the cold surface — It ranks high because a full defrost both confirms the diagnosis and restores production within a day.
- The cabinet packed so that cold cannot circulate — Then: it also holds frost against the plate, so it makes the frost cause worse at the same time.
- The unit no longer reaching its lowest temperatures — Last, and the reason the order matters: a system that has lost capacity can still cool a compartment reasonably while never again reaching freezing temperatures. Ice production is the first thing to go and the last symptom to be understood.
Working order, and the reason for it
- Measure the compartment rather than judging it by hand — Put a thermometer where the ice is meant to form and read it after several undisturbed hours. A compartment that is cold but not properly freezing explains slow ice, hollow cubes and none at all.
- Look at the plate before anything mechanical — Note where the frost is thickest; that is where warm air is arriving, and it is the fault behind the fault.
- Unload and leave the air paths clear — Unload, leave clear space at the cold surfaces and the air paths, and run it undisturbed. Production returning within a day is the answer.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into an ice maker; a capacitor can hold a charge after the power is off, and a mechanism can cycle without warning. Never use a sharp tool against the mould or the liner to free ice.

Where owner work ends
Call when water is proven to arrive, the compartment is proven properly cold, the bin is clear and a full cycle still produces nothing: at that point the mechanism or the capacity is the remaining answer. Call at once for oil at the machinery end or a breaker that trips.
