In one paragraph
For a A unit: a cabinet that stays warm while the compressor keeps running is almost never a dead compressor. Far more often the cold is being made and not moved: a frosted evaporator, a stopped circulating fan, or a condenser buried under dust. Two of those three are things an owner can see without a tool. That is the same list the brand-generic page carries, in a different order.
What an owner actually sees on a A unit
- The freezer is cold but the fresh-food side is not — Cold is being made; it is not arriving. That points at the vent between the compartments rather than at the sealed system. It is the first thing worth confirming on a A unit.
- The unit is noticeably louder than it used to be — A compressor that never rests is running in a duty cycle it was not designed for.
- The fresh-food vent is cold to a hand held in front of it — Air is arriving, so the damper and the vent are working and the fault is further back.
- NEAR MISS: the unit is silent and nothing is cold — That is a no-power or start-relay fault, and it belongs on a different page. A reader who sees this should leave for that one.
The ranking on the A line
- Airflow blocked by a frosted evaporator — Ranked first because it builds slowly and quietly: the defrost cycle stalls before it fails outright, ice sheets over the coil for weeks, and the owner notices the warmth long before the frost. On a A unit this is still the first thing to eliminate.
- A door seal that no longer seals — A gasket that has gone hard or has torn at a corner admits room air all day. The compressor runs longer and longer against a load it cannot win.
- Food packed against the air vent — It costs nothing to move and it starves a compartment exactly the way a failed damper does, which is why it is worth ruling out early.
- A sealed-system or compressor fault — Last, and that ranking is the point of this page: it is the least likely cause on the list and the only one that is not an owner check. Anyone naming it first has skipped every cheaper answer above it.
What to check first, second, third
- Look at the freezer rear panel for a frost sheet — If the fan runs and the panel is iced, airflow is the fault and the defrost system is what is behind it. The A layout is the reason it comes first here.
- Close the door on a sheet of paper and pull it out — If it slides free with no drag anywhere along the frame, the gasket is the reason the compressor never rests.
- Watch whether the compressor ever stops — Continuous running with no cycling means the unit is never reaching its set point, which narrows the list to heat rejection and airflow.
- Count how long the unit has been in its current position — A unit pushed back tight against a wall after a kitchen move has a heat-rejection problem that has nothing wrong with it at all.
What to do before you start
Safety
Switch the breaker off before opening anything, because a capacitor can stay charged after the power is off. Treat every tube at the back as pressurised. Refrigerant work is licensed work, and the tools for it are not owner tools.

When to stop and call
Once frost, coil, gasket and vent have all been ruled out, the remaining causes need a meter and a manifold, and both belong to a technician. Call sooner if the cabinet is warming while the compressor is silent — that is a different and more urgent fault.
