The version worth reading first
On the ATMSL 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 five listings, ATMSL181, ATMSL181TH and ATMSL212E, plus the starred variants of those numbers shown in the table below.
What the cabinet is doing
- 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.
- Food in the door is spoiling before food at the back — Door storage is the warmest part of the cabinet, so it fails first. Useful as an early warning, not as a diagnosis.
- 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.
Ranked causes
- Frost across the evaporator blocking airflow — Top of the list because the coil is hidden behind the freezer liner on these listings, so nothing warns the owner until the cabinet is already warm. The tell is a solid frost sheet on the rear freezer wall rather than the usual light dusting.
- 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.
- 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
- 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: 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 ATMSL 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
Stop at the point where observation runs out and measurement begins. On the ATMSL listings a thermistor reading wrong and a damper stuck shut look identical from the front, and guessing between them costs more than asking. Call immediately for oil in the machine compartment.
