The short answer for the NPYY models
On the Alcove NPYY 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 NPYY family carries one model code and no more, so the family is a single build rather than a series of variants.
What you observe on these models
- Ice tastes or smells of the freezer — A turnover problem rather than a production one, and usually a filter is overdue as well.
- Cubes are small, hollow or only half formed — The cycle is running but the fill is not what it should be.
- 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.
- 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 NPYY family
- The shut-off arm or sensor reading full — Anything resting against the arm has the same effect as a full bin, including ice that has fused into one lump under it. Ranked first here.
- Ice in the fill tube or the mould — A slow fill freezes before it finishes, and the next cycle adds to it until the tube is blocked solid. Second.
- The ice maker module or its motor — The expensive end of this list, and genuinely rare compared with everything above it.
- 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.
- Look for a rod of ice at the fill point at the back of the freezer — Second: 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 — Third: 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
The line is the first step that needs a meter on live terminals, or any sign of the ice maker module or its motor. Everything before that point is an owner check; everything after it is a service call. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
