The short answer for the NN models
On the Alcove NN refrigerator models, an ice maker that has stopped producing, or produces badly leads with the shut-off arm or sensor reading full rather than with the cause the brand-generic article opens on. The spine for the NN family records one model code, which is to say the family and the machine are the same thing.
What you observe on these models
- A rod of ice sits where the water enters the freezer — The fill is freezing before it finishes, and each cycle adds to what is already there.
- No ice at all and the bin has stayed empty for days — Nothing has been produced, rather than ice being produced and stuck.
- You can hear the maker cycle but nothing arrives — The timing is right and the water is not. That is a supply answer, not a module one.
- The dispenser jams although the bin has ice in it — Fused cubes are stopping the auger, which reads as a dispenser fault and is not one.
- NEAR MISS — there is water on the floor as well as no ice — That is the water-leak page for this appliance, and it is the more urgent of the two.
Causes, most likely first on the NN family
- The shut-off arm or sensor reading full — A bail arm nudged up by a bag, or an optical sensor with frost across it, tells the maker the bin is full. It then stops, correctly. Ranked first here.
- The fill valve or its screen — A valve fed at low pressure, or through a partly closed shut-off, half-fills the mould and produces small cubes on time. Second.
- The ice maker module or its motor — Ranked last deliberately: most ice complaints are water, temperature or the arm, and all three are found without a meter.
- Body: The cause that moves up on these models is the shut-off arm or sensor reading full; what moves down to make room for it is ice in the fill tube or the mould, which is where the brand-generic article for this symptom opens.
Check in this order, and why
- Look at the bail arm or the sensor window and clear anything touching it — First: A raised arm is an instruction to stop, and the maker is obeying it.
- Run the dispenser and see whether water arrives at normal pressure — Second: A dispenser that runs freely proves the supply; one that dribbles proves the restriction.
- Look for a rod of ice at the fill point at the back of the freezer — Third: That is a slow fill freezing in place, and it explains both small cubes and none at all.
- Check the age of the water filter and when it was last changed — Fourth: Restriction shows as small cubes well before it shows as none.
Before you open anything
Safety
Power off at the plug or the breaker before anything is opened. A capacitor keeps its charge after the switch, and the fan behind the rear panel can start on its own. The sealed refrigerant side is licensed work rather than owner work. Deal with the food first: a refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below, and a freezer at 0 degrees Fahrenheit.

When to call a technician
Owner work ends where the meter begins. Book the visit once the free checks are exhausted, or immediately if the evidence already points at the ice maker module or its motor. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
