The answer before the explanation
An ice maker is the most complicated assembly in a domestic refrigerator and the one owners judge most harshly. On the CR models most stoppages are supply-side or temperature-side, which means they are diagnosable from the kitchen with nothing in your hand.
What owners of these models report
- The mould is full of water that never freezes into a harvest — Water arrives but the compartment is not cold enough or the harvest is not triggering.
- NEAR MISS - ice tastes stale but production is normal — That is a storage and filter question, not a production fault, and it belongs elsewhere.
- Production stopped after a water filter was changed — Air in the line or a filter that is not seated, and it is the single most common recent-change cause.
- The arm or the bin sensor reports full when the bin is empty — The control is being told to stop, and no amount of looking at the water side will show it.
- The maker cycles, you hear the harvest, but nothing lands in the bin — The cubes are sticking in the mould, which is a fill-level or a mould-heater question.
What it usually turns out to be
- Freezer compartment not cold enough to harvest — Second, and the one owners least expect. The mechanism is fine; the compartment simply never reaches the condition that triggers a harvest.
- Mould heater or ejector failing — This is the cubes-stick-in-the-mould branch, and it is diagnosed from that symptom rather than from a general stoppage.
- Fill valve failing or its screen blocked — The valve is the part that owners suspect first and that fails fourth; a blocked inlet screen mimics a failed valve exactly.
- Bin arm or sensor reporting full — Cheap to rule out and easy to knock out of position when reaching for something in a crowded freezer.
Check in this order, and why
- Look in the mould: dry, full of water, or full of ice — Three states, three different branches of the diagnosis, and one look picks the branch.
- Watch a full cycle with the bin out — Slow but conclusive: you see fill, freeze and harvest in sequence and can name the step that fails.
- Re-seat the water filter and run several glasses through the dispenser — Clears air from the line and proves the supply in one action, and it is the first thing to do after any filter change.
- Check the fill tube for a plug of ice — Third because the bin usually has to come out, but on this family it is the single most productive look you can take.
Before any panel comes off
Safety
Unplug before servicing, and leave the door switch alone. It cuts the fan when the door opens so that nothing is turning while your hand is inside; it is not the thing to defeat to make a test easier.

When to call a technician
The line is the panel. Anything you can reach with the door open is yours; anything that needs the rear access panel off, a sealed-system gauge set or a wiring diagram belongs to a technician who carries all three.
