The version worth reading first
On the ABMP roster the most useful thing you own is a thermometer. The family covers one base number, ABMP171E, carried twice in the parts data. Hands cannot tell a cabinet at its set point from one several degrees above it, and almost every wrong turn in this diagnosis starts with trusting one.
How it presents
- Ice cream is soft but the freezer looks frozen — A freezer holding above its safe temperature still looks normal. Only a thermometer settles it.
- Only one shelf or one drawer is warm — Localised warmth is a vent or a loading problem, not a system fault. Something is blocking the delivery path to that spot.
- 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 it usually turns out to be
- 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 — Sits second on these models. Cold is being made and is not being moved, which is why the freezer can still feel acceptable while the refrigerator section is failing.
- 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.
- 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 sequence that saves time
- 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.
- Pull the unit out and inspect the condenser area — Dust, pet hair and a tight wall clearance all degrade heat rejection. Worth doing once the cabinet-side checks are clean.
- 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: 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 you open anything
Safety
Isolate the unit before any panel is removed - unplug it or switch off its breaker - and a capacitor can hold a charge after the power is off. Do not run the cabinet with the liner panel off to watch the coil: the fan is unguarded once the panel is away and the fins are sharp enough to cut through a glove.
Models in the ABMP family — Every listing this page generalizes over. Check the number on your rating plate against it before ordering a part. 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.

Where the owner line is
Call once the thermometer, the seal check and the vent check are clean and the cabinet is still warm. On the ABMP 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.
