The short answer
On the ALERF line, a cabinet that hums but will not hold temperature is far more often an airflow or heat-rejection problem than a dead compressor — the machine is still working, it just cannot move the heat out. On this page heat rejection is checked before airflow: a coil that cannot dump heat starves everything downstream of it, and it is visible without tools.
What an owner actually observes on the ALERF line
- Condensation or sweating on the inside walls — The cabinet is running above dew point for the room, which is the same fault seen from the humidity side.
- The cabinet is warm and the unit is plainly running — You can hear the compressor and feel warm air at the back, but the inside never comes down to temperature.
- NEAR MISS — the cabinet is silent and nothing is cold — That is a no-power, start-relay or control fault and it is a different page: it starts with the outlet and the cord, not with the airflow checks below.
The ranking for the ALERF line, likeliest first
- The condenser coil is blanketed in dust, or its fan has stopped — Ranked first here because it is the cheapest fault to have and the cheapest to rule out: a coil that cannot shed heat makes a cabinet that runs constantly and cools poorly, and on the ALERF line the coil sits where household dust and pet hair reach it.
- Defrost has stalled and the evaporator has iced over, so no air moves — A stalled defrost cycle ices the evaporator until air can no longer pass it, which warms the cabinet while the compressor keeps working. It sits here because the checks above it are quicker to clear, not because it is rare.
- The evaporator fan has failed, seized or is being blocked — The evaporator fan is what pushes cold air into the compartments. When it stops, the coil still gets cold but the cabinet does not, which reads exactly like a cooling failure from the outside.
- The door is not sealing — gasket, alignment or a shelf holding it open — At the bottom of the list, but never skip it: if everything above checks out, a seal that fails only under its own weight, or only when warm, is the classic answer to a fault that comes and goes.
The diagnostic order, and the reason for it
- First — find the condenser coil and its fan, and look — Pull the cabinet out or take the base grille off.
- Then — look at the back wall of the freezer compartment for a sheet of ice — Empty the compartment and look at the vents.
- Only then — listen at the freezer with the door switch held in — The evaporator fan should start within a few seconds.
- STOP here if the next check needs a panel off or a meter on live terminals — Everything above can be done with nothing dismantled; past it the checks need test equipment.

Read this before any panel comes off
Safety
Unplug the appliance or switch off its breaker before any panel comes off — a capacitor can hold a charge after the power is off, and the compressor circuit is live whenever the cabinet is plugged in even when it is silent. Do not defrost a coil with a heat gun or a sharp tool: puncturing an evaporator tube turns a service call into a replacement.
When it stops being an owner job
Call once the checks above are clean, or as soon as the evidence points inside the sealed system: refrigerant work is licensed work and the gauges to do it are not owner tools. On the ALERF line, call rather than continue if the coil has to come out to be cleared, if the fan needs the evaporator cover off, or if the cabinet trips the breaker when it starts. Call the same day if the freezer has been above 0 °F (−18 °C) or the fresh-food side above 40 °F (4 °C) for longer than a few hours, because at that point the food is the more expensive problem.
