A 15-inch Monogram ice maker whose catalog status is still unconfirmed, which makes the label check essential.
The UNC15NJII is a 15-inch ice maker from the UNC nugget family. Unlike most models we list, its current or discontinued status is not settled. That is why the first job on any visit is reading the label: it tells us the exact variant and what parts to look for. The category background is in our Monogram ice maker repair and the Monogram ice makers.
A narrow ice maker usually lives beside a sink or under a counter, close to water and often close to a dishwasher. That neighborhood produces its own faults:
Owners tell us about thin production, ice that clumps, small leaks and a bin that stops filling. Sometimes the unit runs but the noise has changed. Each symptom has a short list of causes, and a technician works them down from the simplest.
Open the water valve fully, check the cord and breaker, empty the bin and look for jammed ice. Read any light and write it down. You may find a match among the code pages, such as OFF light 2 blinks or OFF light 3 blinks, though they describe ice makers in general and do not confirm anything for this model. Do not open the cabinet.
We diagnose first, share a written estimate and start nothing without your go-ahead. A photo of the label speeds things up.
The same prefix appears on the current UNC15NPWII.
A narrow unit has little spare capacity. When production falls, owners notice at once, because the bin holds only a modest amount. Cleaning on schedule, keeping the supply valve fully open and leaving breathing room around the cabinet are the three habits that keep a narrow machine out of trouble.
Check whether the cabinet around the unit feels warm, whether the sink above it has been leaking, and whether any light is on. If the ice maker stopped right after a plumbing job nearby, say so; a closed valve or a loosened hose is a more likely cause than anything inside the machine.
Read the label before ordering parts, so the exact version is matched.
Variants can look the same from the front but differ inside, and the label identifies the exact one.
Usually inside on a wall of the cabinet, near the front edge.
Most built-ins need a drain path for melt water, and a technician checks it.
