The short answer
Running but not cooling is a delivery fault far more often than a production fault, and the models on this roster are no exception. Ice sheets across the evaporator, the fan can no longer push air through it, and the compartment climbs even though the compressor never stops. Most of what follows is owner work. The one item that is not is also the least likely, which is why it sits at the bottom of the list. Several listings carry a letter suffix; on this brand that marks a finish or a revision rather than a different machine.
The observable pattern
- The freezer holds and the fresh-food side is only slightly warm — A partial airflow loss, usually the beginning of the ice build rather than the end of it.
- A sheet of frost across the back wall of the freezer — Not the usual light dusting that comes and goes, but a solid layer that does not clear between cycles.
- The cabinet cooled normally until a defrost cycle, and not since — A defrost that ran and did not finish leaves the evaporator part-thawed and the drain part-blocked, and the unit never recovers on its own.
- The outside of the cabinet, near the hinges, is unusually warm — Some of these cabinets run condenser tubing through the shell. Warm there is normal; hot enough to be uncomfortable is not.
- NEAR MISS — the cabinet is cold but the icemaker is empty — Cold air with no ice is its own fault path and has its own page for this family.
What it turns out to be, in order
- Airflow blocked by a frosted evaporator — First on this roster, and by some distance. Adaptive defrost on these cabinets stalls before it fails outright, so ice accumulates over weeks and the owner notices the warmth long before the frost.
- Condenser coil choked with dust or pet hair — Frequent, invisible and free to fix. Heat that cannot leave the coil is heat that stays in the cabinet, and on a bottom-mounted coil nobody ever looks at it until something goes wrong.
- Defrost heater, thermostat or timer fault — This is what makes the frost in the first cause permanent rather than cyclical. It is the point where owner diagnosis usually stops and a meter is needed.
- Sealed-system or compressor fault — Last, and the reason the order matters. It is the least likely cause on this roster and the only one that is not owner-serviceable at any level.
What to check first, second, third
- Listen at the freezer with the door open and the switch held in — The evaporator fan should run. Hearing it separates the two likeliest causes before any panel comes off.
- Pull the cabinet out and look at the condenser coil — Dust and pet hair pack into a bottom-mounted coil until it cannot shed heat. This is the one step that is both common and invisible from the front.
- Empty the cabinet and run it with the doors shut overnight — Removes the load and the door openings as variables. What it does overnight tells you what kind of fault this is.
What to do before the panel comes off
Safety
Nothing below happens with the machine live. Unplug it or switch off its breaker, and treat any capacitor as charged until it has been discharged properly.

When this stops being owner work
Anything reachable without a tool is yours; anything that needs the rear panel off is a service call on this family, because the panel is foamed against the liner on some of these listings and comes off in one direction only. Refrigerant work is licensed regardless of who is holding the gauges.
