What this usually is
On the ABMA roster the most useful thing you own is a thermometer. The family covers one base number, ABMA171E, 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.
Symptoms on these models
- 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 a technician expects to find
- Frost across the evaporator blocking airflow — At the top because it is the only cause here that a manual defrost will temporarily fix, and that reversibility is itself diagnostic: a cabinet that works for a day after being emptied and left open has told you where to look.
- 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.
- Condenser coil or machine-compartment airflow blocked — Here because it is a capacity problem rather than a failure: the system still works, it simply has less margin, so the cabinet fails on the hottest day rather than not at all.
- 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: Ordered by what is found on a cabinet with this airflow layout. The evaporator fan sits high because on these listings it is inside the cold compartment, where it collects exactly the ice the defrost system was meant to remove.
Diagnostic order on these models
- 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.
- 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: This order is deliberately slow at the start. A thermometer left in the cabinet for a few hours is worth more than any amount of opening the door to feel, and it is the step most often skipped.
Before a panel comes off
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 ABMA 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
Call once the thermometer, the seal check and the vent check are clean and the cabinet is still warm. On the ABMA 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.
