The short answer
A the AFB refrigerators cabinet that hums steadily and still will not hold temperature is telling you the cooling is being made and not delivered. On these models a frosted evaporator is the first thing this page would have you rule out. Every cause below can be checked by the owner, which is why the order matters more than the list.
What you observe on these models
- The freezer still works and the fresh-food side does not — A split like that points at air movement rather than at cooling.
- The appliance never cycles off — It runs on and on without ever reaching the setting.
- Food at the back is frozen while the front is warm — Cold is reaching part of the compartment and not the rest.
- NEAR MISS — water is pooling but the box is cold — That is a drain fault rather than a cooling fault.
Causes, most likely first on this family
- Airflow blocked by frost on the evaporator — Frost across the evaporator face is the commonest reason a refrigerator runs without cooling, because the fault hides behind a panel and makes no sound of its own. Ranked first here: the commonest of the four on this family. This family is a single build, so it holds across the line.
- Return-air vents blocked by the load — A cabinet packed to the back wall blocks the return path, so the air that did get cold never comes back to be cooled again. Second, because it produces almost the same complaint from a different part.
- Condenser fan not turning — A condenser fan that stops leaves the compressor hot enough to trip its own overload, so the appliance cycles on and off without ever pulling the box down. Third, because the two above account for most of what arrives with this complaint.
- Cold control or thermistor reading wrong — On a mechanical cold control the same complaint is a capillary bulb knocked off its clip, which costs nothing to put back. Last on this page: real, but uncommon on these cabinets.
- Body: Against the brand-wide order, installation and loading causes move up here and wear causes move down: one build means a narrow spread of ages in service, so how the cabinet was put in matters more than how long it has run.
Check in this order, and why
- Take the freezer rear panel off and look at the evaporator face for a solid sheet rather than a light dusting of frost. — It leads: the ranking puts this cause first, so its check goes first too.
- Clear the rear and upper vents in both compartments and give the appliance a full day before judging it. — It sits here because it rules a cause in rather than out, which saves a step later.
- With the compressor running, check from the back that the condenser fan blade is turning, and turning freely. — Last, because it confirms what the checks above have already narrowed.
Before you take a panel off
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Leave the door switch wired as it is: it cuts power to the evaporator fan for a reason. Keep the doors shut meanwhile and move perishables to a cooler: a refrigerator holds food safely at 40 °F (4 °C) or below, a freezer at 0 °F (−18 °C) or below.

When to call a technician
The line is the rear panel. Everything in front of it is an owner check; the evaporator, the defrost circuit and the sealed system behind it are not. Call straight away if the compressor is hot enough to smell.
