What the cabinet is telling you
A ABML 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, ABML171E, 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.
How it presents
- Both compartments are warm and the unit is running continuously — Cold is not being made, or the coil is so iced that nothing passes it. This is the pattern that needs the freezer liner panel off.
- 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 by what actually turns up
- 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.
- Door seal, door alignment or a door left ajar — Cheap, common, and it mimics everything else on this list. A seal that has taken a set or a door held fractionally open by an overloaded shelf feeds warm moist air in continuously, which both warms the cabinet and feeds the coil the moisture that ices it.
- Control, thermistor or damper fault — Ranked below the mechanical causes because it is less common and because confirming it needs measurement rather than observation. It is the cause to suspect when the coil is clear, the fan runs and the cabinet is still warm.
- 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 ABML listings, and none of the three requires the sealed system to be touched.
The order to work in
- Put a thermometer in each compartment and wait — A refrigerator holds food safely at 40 degrees Fahrenheit or below and a freezer at 0 degrees Fahrenheit or below. Knowing which compartment is actually failing decides everything that follows.
- 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.
- 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.
Safety first
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 ABML 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 this stops being an owner job
Call once the thermometer, the seal check and the vent check are clean and the cabinet is still warm. On the ABML 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.
