The short answer
A ABMF refrigerator that is warming has three cheap causes and one expensive one, and the expensive one is the least likely of the four. The roster covers one base number, ABMF171E, carried twice in the parts data. That ratio is the whole reason for working down this page in order rather than starting at the compressor.
Symptoms on these models
- 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 - cooling is fine but the ice maker has stopped — An ice maker that has stopped while the freezer is still cold is its own fault path and has its own page for this family.
What it usually turns out to be
- 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.
- 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.
- 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 — At the bottom because this is where the money is. Every entry above it is cheaper to test, and a wrong guess here is the difference between a service call and a new appliance.
- 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 ABMF 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.
- 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.
- 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 you open anything
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 ABMF 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.

Where the owner line is
Stop when the next check needs the compartment emptied or the sealed system opened. On the ABMF 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.
