The short answer for this family
On the Criterion CWC refrigerator family the first question is not why the icemaker stopped but whether these models carry one at all: a glass-door drinks cabinet does not make ice and is not plumbed for it; the ice question here is almost always about frost or about a cabinet running too cold. Where one is fitted, the fault splits cleanly into a water side and a cold side, and the mould tells you which. One model in the roster, so the notes below apply exactly.
What you observe on these models
- It makes ice, but far less than it used to — Reduced output with correct cubes is nearly always a cabinet running warmer than it was, or a filter at the end of its life.
- No ice at all, and the mould is dry — A dry mould means no water is arriving: supply, valve, filter or fill tube. A wet mould that never harvests means the cold side instead.
- Frost or an ice sheet growing where there should be none — Ice anywhere in a wine cabinet is a fault, because this cabinet is not supposed to run below freezing at all.
- NEAR MISS: the cabinet is also not holding temperature — Ice output is the first thing a cabinet gives up when it runs warm. If the compartment is warm too, read the cooling page first.
Ranked causes for this family
- These models do not all carry a factory icemaker — First here because it is the answer for most owners of this family: a glass-door drinks cabinet does not make ice and is not plumbed for it; the ice question here is almost always about frost or about a cabinet running too cold. Establish whether your model has one, and whether it is factory or an accessory.
- Ice forming where it should not, rather than failing to form — On this family the question is usually the other way round. Ice anywhere in a wine cabinet is a fault, because this cabinet is not supposed to run below freezing at all. That is the version of this fault most owners of this family actually meet.
- The compartment is not cold enough to harvest — An icemaker will not cycle until its mould reaches cut-out, so a warm compartment gives slow ice or none with nothing wrong in the icemaker. A freezer holds food safely at 0 °F (-18 °C) or below.
The checking order on these models
- Establish whether this model has a factory icemaker at all — Check your model number against the roster below and look inside the compartment. On this family that check answers the question for most owners, and it costs nothing. Each step rules out a cause the next one would inherit.
- Look for stray ice and ask where the water came from — Ice anywhere in a wine cabinet is a fault, because this cabinet is not supposed to run below freezing at all. Ask where the water came from before you clear it, because clearing it without answering that question guarantees it returns.
- Check the compartment temperature before the icemaker — A compartment sitting above where it should be explains slow ice, clumped ice and no ice with nothing wrong in the icemaker itself.
Safety first
Safety
Unplug the appliance or switch off its breaker before removing any panel or icemaker assembly; a capacitor can hold a charge after the power is off. Where the cabinet is plumbed, shut the water supply off before touching a fitting, and never thaw a fill tube or a frozen line with a flame or a heat gun: hot air melts the surrounding plastic long before it clears the ice. Do not chip ice off any surface with a screwdriver, because the tubing behind it is soft aluminium.

Where the owner line falls here
Where the line falls here is worth stating plainly. Checking the supply, the filter, the bail arm and the compartment temperature is owner work. Call when the mould is wet and never harvests, when the fill tube re-frosts within days of being cleared, or when the ice problem is really a temperature problem, because that moves the job into the cold path. On this platform a glass door is heavy and easily damaged, and it is the part that gets broken when a cabinet is worked on in place.
