The short answer for the NPWHI models
On the Alcove NPWHI refrigerator models, an ice maker that has stopped producing, or produces badly leads with a door that is letting damp air in rather than with the cause the brand-generic article opens on. The spine for the NPWHI family lists a single model code, so there is no variant spread to account for here.
What you observe on these models
- 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 NPWHI family
- A door that is letting damp air in — Where ice production has gone strange rather than stopped, the door seal is worth proving before anything is dismantled. Ranked first here.
- A water filter at the end of its life — This is the cheapest thing on the list and the one most often overdue, which is why it is worth proving early. 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 a door that is letting damp air in; 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
- Check the age of the water filter and when it was last changed — First: Restriction shows as small cubes well before it shows as none.
- Measure the freezer temperature before assuming the maker is dead — Second: A maker will not harvest from a mould that has not reached temperature, and a warm freezer explains the whole symptom.
- Pull the cabinet out and look for a kinked or pinched supply line — Third: A line trapped when the cabinet was pushed back is the most common outside fault.
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
Stop and call at the point where a panel has to come off with power on, and call without hesitating if what you are looking at is 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.
