The short answer
On the ABMS roster the pattern that matters is which compartment warmed first. These listings feed the fresh-food side with air that has already passed the freezer coil, so a freezer that is still cold while the refrigerator section is warm is a duct or fan problem, and a cabinet that is warm throughout is something else entirely. The roster covers four listings, ABMS141E, ABMS170E and ABMS171E, plus the starred variants of those numbers shown in the table below.
The observable signs
- A sheet of frost on the rear freezer wall — Not the usual light dusting but a solid layer. It is the single most useful visible tell on these models and it is visible before any panel is removed.
- 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 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 causes
- Frost across the evaporator blocking airflow — First on this roster. Adaptive defrost stalls quietly rather than failing outright, so ice builds across the coil over weeks. Air stops passing, the fresh-food side warms first, and the compressor runs on without ever reaching its set point.
- Failed or obstructed evaporator fan — Second. The fan lives inside the cold compartment on this roster, so it takes the brunt of any ice that escapes the coil area and it is the part that wears. A cabinet with a good coil and a stopped fan looks identical from the front to one with a blocked coil.
- 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.
- Compressor, start relay or sealed-system fault — Ranked last because it is both least common and most expensive, which is the combination that punishes a guess. Have the cause named before you decide whether the cabinet is worth repairing at all.
- Body: This order is built so that the free checks come first and the licensed work comes last. On the ABMS roster that is not a compromise: the free checks are genuinely the likeliest findings, and ordering by cost happens to order by probability too.
Work through this in order
- 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.
- Check the door seals and how the doors sit — Close a sheet of paper in the door and pull. If it slides out freely, the seal is not gripping and warm moist air is entering continuously.
- Body: Each step eliminates a branch rather than a part. The roster covers more than one number series, so confirm panel layout and damper position against your own rating plate before ordering anything.
Before a panel comes off
Safety
Isolate the unit before removing panels - unplug it or switch off its breaker - and treat the door switch as part of that isolation, because on this cabinet it is what starts the freezer fan. A capacitor can hold a charge after the power is off. Refrigerant work is licensed work; if the fault is on the sealed system, stop.

When to stop and call
The owner line on this roster is the freezer liner panel. In front of it: thermometers, seals, vents, the condenser area. Behind it: the coil, the defrost heater and the fan, all of which need the cabinet emptied and the fins protected. Anything on the sealed system is licensed work regardless of skill.
