Loss of cooling on an Arctic Wind ABMM 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, ABMM171E, 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.
- Food in the door is spoiling before food at the back — Door storage is the warmest part of the cabinet, so it fails first. Useful as an early warning, not as a diagnosis.
- NEAR MISS - the unit is completely silent and nothing is cold — That is a no-power, start-relay or control fault rather than an airflow fault. Different diagnosis, different page.
Ranked by what actually turns up
- Frost across the evaporator blocking airflow — First because a stalled defrost is invisible to an owner until the cabinet is already warm, and by then the ice has been building for weeks. Nothing about the symptom points at defrost, which is exactly why it goes unfound.
- Condenser coil or machine-compartment airflow blocked — Placed at this point because owners reach the condenser during normal cleaning far more often than they reach anything on the cold side, so it is more often already clean than not.
- Control, thermistor or damper fault — Ranked below the mechanical causes because confirming it needs measurement, and because it is the explanation left standing when everything visible has checked out.
- Compressor, start relay or sealed-system fault — Last because refrigerant work is licensed work, the tools are not owner tools, and the probability of this being the answer is the lowest on the page.
- 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.
The order to work in
- Open the freezer and look at the rear wall — A solid frost sheet rather than a light dusting is the single most informative thing visible without tools on this cabinet.
- Listen for the evaporator fan with the door open, then closed — The door switch gives you a free test of whether cold air is being moved at all.
- Body: Each step eliminates a branch rather than a part. The roster is one number series, so the layout below holds across every listing on this page.
Before a panel comes off
Safety
Unplug the appliance or switch off its breaker before any panel comes off, and remember a capacitor can hold a charge after the power is off. Do not use a heat gun or a hair dryer against the liner to speed a defrost; the plastic distorts and the damage is permanent. Time and open doors do the same job safely.
Models in the ABMM 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 thermometer, the seal check and the vent check are clean and the cabinet is still warm. On the ABMM roster the next step is the liner panel, which means an emptied compartment and exposed fins. Call immediately if the compressor is hot and silent, if a relay is clicking repeatedly, or if there is oil in the machine compartment.
