The short answer
Loss of cooling on an Arctic Wind ABMJ refrigerator splits cleanly in two: the unit is not moving cold air, or it is not making cold at all. This page covers one base number, ABMJ171E, carried twice in the parts data. Telling those apart takes about two minutes and no tools, and it decides whether this is a service call or a defrost and a clean.
What the cabinet is doing
- The refrigerator section is warm but the freezer is still cold — The classic airflow split on this cabinet type. Cold is being made and is not reaching the fresh-food side, which points at the duct or the fan rather than the sealed system.
- The compressor never cycles off — A unit that runs without ever reaching its set point is the same fault seen from the other side, and it is the one that makes a cheap fault expensive if left.
- NEAR MISS - the cabinet is cold but water is pooling inside — A blocked defrost drain with cooling intact belongs on the water-leak page for this family.
What it usually turns out to be
- Frost across the evaporator blocking airflow — Top of the list because the coil is hidden behind the freezer liner on these listings, so nothing warns the owner until the cabinet is already warm. The tell is a solid frost sheet on the rear freezer wall rather than the usual light dusting.
- Door seal, door alignment or a door left ajar — Ranked above the machine-compartment causes because it costs nothing to check and because on this roster a failing seal is also the most common reason the coil iced in the first place. Two faults, one cause.
- Control, thermistor or damper fault — Ranked below the mechanical causes because it is less common and because confirming it needs measurement rather than observation. It is the cause to suspect when the coil is clear, the fan runs and the cabinet is still warm.
- Compressor, start relay or sealed-system fault — Bottom of the ranking. The tells are a compressor that is hot and silent, a relay that clicks and drops out repeatedly, or oil visible in the machine compartment. Oil outside the tubing means the system is open.
- Body: The sealed system sits last for a reason. It is the least common cause of a warm cabinet and the only one that cannot be confirmed without gauges, so guessing it first is how owners end up replacing an appliance that needed a defrost.
Check in this order, and why
- Feel whether the machine compartment is rejecting heat — Warm is expected; cool while the compressor runs is not, and it points somewhere quite different from a blocked coil.
- Note which compartment failed first — Fresh food first means the cold is being made and not delivered; both together means it is not being made.
- Body: Work down this list. The first two steps need nothing but a thermometer and a few minutes, and between them they decide whether this cabinet has an airflow problem or a cold-making problem - which is the only fork that really matters.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Move perishable food to a cooler with ice before starting, and keep the doors shut otherwise, because every opening costs cold air the cabinet cannot currently replace.
Models in the ABMJ family — The roster this page covers, taken from the model spine. Every listing in the roster shares one number series, so the access notes below hold across the roster. A starred entry in the table is the same base number recorded a second way in the parts data; treat it as the same platform for this fault unless your own parts diagram says otherwise.

When this stops being an owner job
Call once the free checks are done, because past that point the diagnosis needs measurement rather than observation - a thermistor reading wrong and a damper stuck shut look identical from the front. Call immediately if the unit is warm throughout, silent, and the plug and breaker are both confirmed good.
