What the cabinet is telling you
An Arctic Wind ABMT refrigerator that has stopped holding temperature is worth triaging before it is worth repairing. The roster covers one base number, ABMT171E, carried twice in the parts data. A refrigerator holds food safely at 40 degrees Fahrenheit or below and a freezer at 0 degrees Fahrenheit or below, so the first useful action is a thermometer in each compartment rather than a screwdriver.
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.
What a technician expects to find
- 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.
- Failed or obstructed evaporator fan — Placed at this point because the fan is the moving part in the cold space, and moving parts in cold spaces are where wear concentrates on a cabinet of this layout.
- Door seal, door alignment or a door left ajar — Ranked here because it is free to check and because it causes the cause above it: the moisture a failing seal admits is what becomes the ice on the coil. One test, two faults ruled 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: This order is by finding frequency, not by part cost. The first three entries account for the large majority of warm-cabinet calls on cabinets laid out like the ABMT listings, and none of the three requires the sealed system to be touched.
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.
- Empty the cabinet, switch it off and leave the doors open overnight — If it cools properly for a day afterwards, the coil was iced and the defrost side is what needs attention, not the compressor.
- Body: Follow this in sequence and resist skipping to the sealed system. On cabinets of this type the last step on the list is reached in a small minority of cases, and reaching it early costs money that the first three steps usually save.
Before a panel comes off
Safety
Unplug the appliance or switch off its breaker before any panel is removed; a capacitor can hold a charge after the power is off. If you see oil anywhere in the machine compartment, stop and call - oil outside the tubing means the sealed system is open, and running the unit after that point makes the repair larger.
Models in the ABMT family — This page generalizes over every listing in the roster below; where the models diverge for this fault the text says so, and where it does not, they behave alike. 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 to call a technician
Stop when the next check needs the compartment emptied or the sealed system opened. On the ABMT listings that covers the coil, the heater, the fan and everything downstream of the compressor. Call straight away for a burning smell, a tripping breaker, or a cabinet that has warmed suddenly rather than gradually.
