The finding, first
On this family the usual finding behind a warm cabinet is a defrost cycle that has stalled rather than a sealed system that has failed. Ice sheets across the evaporator, the fan can no longer push air through it, and the compartment climbs even though the compressor never stops. Two of the three likely causes are checkable by the owner in a few minutes; the third is not an owner job at all. The table above is the boundary of this page: if your rating plate is not on it, you are on the wrong family.
How it presents
- The compressor never cycles off — It runs without ever reaching the set point, which is the same fault seen from the control side rather than the air side.
- 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.
- 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.
- NEAR MISS — the unit is silent and nothing is cold — Silence is a different page. A dead cabinet is a supply, start-relay or control fault, not the airflow fault this page covers.
Ranked causes for these models
- Airflow blocked by a frosted evaporator — Top of the list here, and by a distance. The defrost logic on these cabinets degrades before it stops, so ice accretes over weeks while the owner notices only that things are less cold than they were.
- Door seal not closing, or a door left ajar by a shelf — Cheap to confirm and easy to dismiss. Warm air arriving faster than the unit can remove it produces continuous running and a cabinet that never gets there.
- Defrost heater, thermostat or timer fault — This is what turns cyclical frost into permanent frost. It is also the point at which looking stops being enough 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.
- Body: The order below is what gets found, not what gets suspected. On this platform the airflow causes account for most of the warm-cabinet calls, and the sealed system accounts for the fewest.
The order to check in, and why
- 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.
- Close the door on a strip of paper at three heights — Paper that pulls out freely anywhere along the seal means the door is not sealing there, and that is a cheap fix that looks like an expensive one.
Before you open anything
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. The cabinet is heavy and unbalanced once the door swings. Get help before pulling it out for the condenser check, and do not stand it on a finished floor on its rollers alone. Nothing on the refrigerant circuit is owner work at any level of confidence. Anything specific to a single listing would belong on a model page; nothing below is.

When this stops being owner work
The owner line on this roster is the freezer rear panel. Clearing vents, cleaning the condenser, checking the seal and thawing the cabinet are all owner work.
