The short answer for these models
Ice trouble is nearly always a water problem, a temperature problem or a clearance problem, in that order. Nothing arrives, so nothing freezes; or the compartment is too warm to finish a batch; or the ice that was made is jamming somewhere on its way out. The part itself is the last thing to suspect. The BUC models take the same faults in a different order: a glazed door leaks far more heat than a solid one by design, so the same fault reads as more severe on a glass-door unit and the baseline you are judging against has to change with it, and the door and glazing checks therefore come before anything else.
What you observe
- How your BUC unit is built — the check that comes before the list — Look at the door itself. Glass sheds far more heat than a solid panel, so longer running, some sweating and a warmer shelf by the door are the baseline rather than the fault.
- A sheet of ice under the bin or over the mould — Ice where ice should not be is water finding a path it should not have.
- The ice maker runs but the bin stays empty — Cubes are being made and then not released, which is a harvest or a jam problem.
Causes, most likely first on this family
- The bin, the arm or the switch is out of position — On the list because a machine that thinks the bin is full behaves exactly like a machine that has failed, and because correcting it costs nothing. This is where the order departs from the brand-level page: on the BUC models the construction settles it, so the door and glazing checks come before the checks that lead anywhere else.
- The fill valve, the mechanism or its heater — Last because it is the diagnosis of exclusion and because confirming it means a meter and a panel off.
The order the checks belong in
- First — look at the mould and the bin — This one check splits the whole diagnosis in half before you touch anything. On these models this is the step the construction changes: the answer only tells you something once you know which form the unit is.
- Second — empty the bin completely and look underneath — Take everything out. Half of these complaints are visible the moment the bin is empty.
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. Never put your hand into an ice maker to free a jam while the machine is live; the harvest cycle starts on its own schedule and it does not know your hand is there. Warm water clears frost safely and nothing sharper should be used.
Where the owner job ends
Book the visit once supply, temperature, the bin and the arm are all accounted for, because a valve, a mould heater or the mechanism all need a meter and a panel off. Tell them whether the mould is wet or dry when you book — that one fact decides which part travels with the technician.
