The short answer for the NPGB models
On the Alcove NPGB refrigerator models, an ice maker that has stopped producing, or produces badly leads with cubes fusing into a single block in the bin rather than with the cause the brand-generic article opens on. The spine for the NPGB family records a single model code, so this is one cabinet rather than a platform run, and everything below is written for that one build.
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.
- NEAR MISS — no ice and the freezer is not really cold either — Deal with the cooling complaint first; the ice maker is downstream of it.
Causes, most likely first on the NPGB family
- Cubes fusing into a single block in the bin — A bin that is emptied rarely will always do this. It also jams the dispenser, which then reads as a second fault. Ranked first here.
- Ice in the fill tube or the mould — This one announces itself: a thin rod of ice at the back wall of the freezer where the water enters. Second.
- The ice maker module or its motor — A module that will not cycle, or a harvest motor that has stalled. Last, and that is the point of the order: it is the least likely and the only one that is not owner work.
- Body: The cause that moves up on these models is cubes fusing into a single block in the bin; 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
- Empty the bin completely and look at what comes out — First: Cube size and shape say more about the fault than the count does.
- 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.
- Run the dispenser and see whether water arrives at normal pressure — Third: A dispenser that runs freely proves the supply; one that dribbles proves the restriction.
- Measure the freezer temperature before assuming the maker is dead — Fourth: A maker will not harvest from a mould that has not reached temperature, and a warm freezer explains the whole symptom.

Safety
Nothing comes off this cabinet until it is unplugged or its breaker is switched off — a capacitor holds a charge after the power is gone, and a fan inside can start without warning. Never defeat a door switch to keep a fan running while you look: it is there to stop a blade turning next to your hand. A refrigerator holds food safely at 40 degrees Fahrenheit, 4 degrees Celsius, or below.

When to call a technician
Call when the checks above have been done and the fault is still there, or as soon as the evidence points at the ice maker module or its motor — that is the one cause here that is not owner work. Call immediately, and unplug the cabinet first, if you smell burning, see oil around the compressor, or hear a hiss with a sharp smell.
