What this usually means
On an upright freezer with an ice maker, a bin that stays empty is almost always a water, temperature or switch problem — and the mechanism itself is the last thing to suspect rather than the first. On a Criterion a shut-off arm raised or the module switched off comes first, because a machine that has just been installed or moved is far more likely to be reporting its setup than its age, and setup faults appear immediately rather than gradually. The shut-off arm, the supply valve, the filter and the cabinet temperature are owner work; the module, heater and fill valve are not. The order below is written for a unit that is new, newly installed or recently moved; a machine that has run in the same spot for years ranks differently.
What the machine is doing
- The mould is full of ice that never ejects — The harvest is failing rather than the fill.
- Ice has welded into a single block in the bin — Slow use plus temperature swings, often behind a marginal seal.
- The mould is dry and the bin stays empty — No water is arriving at all.
- NEAR MISS — The whole cabinet is not cold — Start on the cooling page; ice production stops early when a freezer is struggling.
The causes and their order
- A shut-off arm raised or the module switched off — First on this brand: a machine that has just been installed or moved is far more likely to be reporting its setup than its age, and setup faults appear immediately rather than gradually. The arm stops production when the bin is full and it is very easily left up after the bin is removed for cleaning or the freezer is packed.
- A cabinet not cold enough to trigger the harvest — Second: The harvest cycle starts when the mould reaches a set temperature; a freezer running warm never reaches it and simply stops making ice.
- A closed or crushed water line behind the cabinet — Third, and the last to suspect: A standalone freezer is pushed against a wall, and its supply line is the thing that gets crushed when it goes back. What feeds a machine changes when the machine changes rooms, so on a recent installation the taps, drains, vents and outlets are the first suspects.
Where to start and what follows
- Look for the wire arm or the on-off switch on the module — A raised arm is a complete explanation and takes a second to correct. On a machine that is new to its spot this is checked before anything mechanical, because setup faults arrive immediately and wear faults do not.
- Put a thermometer in the cabinet overnight rather than reading the dial — A cabinet warmer than it should be explains an idle ice maker with nothing wrong in the module.
- Pull the cabinet out and follow the line to its valve — A crushed line or a valve closed during other work is a very common finding.
What an owner can safely check
- Lower the arm or switch the module on, then leave it for several hours — Ice makers are slow; the first batch takes hours rather than minutes.
About 10 min
- Set the freezer colder, keep the vents around the ice maker clear and wait a full day — A day is the minimum before the change means anything.
About 15 min
- Stop here if the next move needs a meter on live terminals — That is where an owner check ends and a service call begins.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Refrigerant is licensed work: oil or a hiss at the compressor means stop and call, and two people move a cabinet this size.
When to call a technician
Call when the arm is down, the valve is open, the filter is fresh and the cabinet is properly cold, and the mould is still not cycling — the module and the fill valve are inside the cabinet. One line to keep in mind while you wait: A freezer holds food safely at 0 °F (−18 °C) or below.
The same machine, other symptoms
What this page does not cover
Everything above is generalized across the Criterion freezer range rather than tied to a model. There is no per-model page under this one today. Where one appears it is linked from this block and it is the page to trust for a specific cabinet. Deliberately not here: wiring colours, resistance values, torque figures and part numbers, which differ between families.
