The short answer
An empty ice bin on a CCUN model usually means one of three things: no water is arriving, the compartment is not cold enough to freeze what does arrive, or the harvest is jamming. The brand-generic page ranks the mechanism first; on this family the supply and the temperature come first, because there is less margin in both.
What you observe
- The ice has fused into one block in the bin — Cubes that melt and refreeze together mean the compartment is riding warm between cycles, or the bin is being opened often in a warm room.
- Ice is made, but far more slowly than it used to be — Slow rather than absent almost always means the compartment is a little warmer than it was, not that the mechanism is failing.
- Water in the bin or frozen under it — The fill is overshooting or the mould is not releasing cleanly, and the overflow freezes where it lands.
- You can hear the mechanism cycle but nothing drops — A harvest that runs without delivering points at a jam in the mould or at ice bridging in the bin rather than at the water path.
Causes, most likely first
- Water not reaching the mould — Ranked first on this family. A closed or partly closed supply, a kinked line behind the cabinet, or a valve that no longer opens fully will empty the bin without any other symptom.
- The compartment riding a little warm — Second, and the cause that most often hides. This platform freezes a small quantity in a small space, so a cabinet running a few degrees above where it should be will keep food cold and still not freeze ice at a useful rate.
- A jam in the mould or bridging in the bin — Ice that has partly melted and refrozen locks the mechanism, and the harvest then runs against a block it cannot shift. It is common after a power interruption or a spell with the door left ajar.
- The ice maker mechanism or its heater — Last. The mould heater that releases each harvest, the motor and the control are all real failures, but on this family they are less common than everything above and they are the part of the job that needs the compartment opened up.
Check in this order
- Check the shut-off arm or sensor is free and nothing is leaning on it — It costs nothing and it explains a mechanism that is not even trying.
- Empty the bin completely and look for a fused block at the bottom — Bridged ice both blocks the harvest and holds the arm up, so it can mimic two different faults at once.
- Look at the size and shape of the last cubes that were made — Full cubes point away from the supply; small or hollow ones point straight at it.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Do not chip frozen ice out of the mould with a blade or a screwdriver: the mould heater and its wiring sit directly under it and a puncture there ends the ice maker.
Models in the CCUN family — The models this page covers, as the product spine lists them. Every model in the table shares one stem and differs only in a trailing code, so a fault found on one of them is a fault the family has.

When to call
Call when the supply is proven good, the compartment is cold enough, the bin is clear and the mechanism still does not deliver. At that point the fault is in the valve, the mould heater or the control, and all three sit behind a panel.
