On the AQF line a cabinet that stays warm while the unit is plainly running is far more often an airflow fault than a dead compressor. The matrix on this page is the definitive list for this family: six model numbers. Two of the causes ranked below are owner-checkable in minutes; the last one is not, and the order matters because working it the other way round costs a diagnostic visit.
What you actually observe
- The cabinet is warm but the unit is clearly running — The unit sounds completely normal, which is exactly why the fault goes unnoticed until food spoils.
- The compressor never shuts off — A unit that used to cycle and now runs flat out is chasing a target it can no longer reach.
- Condensation or sweating inside the cabinet — Warm humid air is being held at a temperature where it gives up moisture instead of freezing it out.
- The back of the unit is unusually hot to the hand — A condenser that cannot shed heat runs hot and drives head pressure up, which shows as poor cooling inside.
- NEAR MISS — the unit is silent and nothing is cold — Silence plus warmth is a start-device or compressor fault, and the checks on this page assume neither.
Causes, most likely first on the AQF line
- Condenser coil blanketed or condenser fan seized — Ranked first on the AQF line because the matrix on this page spans enough models to cross more than one production run — heat rejection is the one part of the job that depends on the room and the coil rather than on which model number is on the badge.
- Stalled defrost cycle icing the evaporator — Second: once heat rejection is ruled out, a frost slab on the freezer rear wall is the next thing that stops cold air reaching the cabinet.
- Thermistor or control board reading the cabinet wrong — Third because a drifted sensor produces a confident and wrong display over a warm cabinet, which is the hardest of the four to suspect and the easiest to confirm with a thermometer.
- Sealed-system or compressor fault — Last, and by some margin. Refrigerant does not get used up; a genuine loss means a leak, and a leak means a technician.
Check in this order, and why
- Pull the cabinet out and look at the coil and its fan before anything else — Both are visible without tools and both undermine everything downstream when they are wrong.
- Watch the condenser fan while the compressor runs — A fan that does not turn and a coil that cannot breathe produce identical symptoms and need different repairs.
- Then check the freezer rear wall for a frost slab — With heat rejection accounted for, ice on the evaporator is the next thing that stops cold air being delivered.
- Compare the display with a thermometer in the cabinet — A wide disagreement points at the sensor rather than the cooling, and that is the cause that hides behind a normal-looking panel.
Before any panel comes 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. The evaporator fan is wired through the door switch on purpose: if you hold that switch in to test the fan, keep your fingers clear of the blade and let go before reaching inside. Nothing on the sealed system is an owner job — the refrigerant circuit is under pressure and is licensed work.

The service-call line
Call once the owner-side checks above come back clean, and call immediately if the fault is on the sealed system. The line on the AQF line is the rear panel: everything in front of it is inspection, and everything behind it needs the cabinet emptied and the evaporator exposed. Call without waiting if you smell burning, see oil around the compressor, or the unit trips the breaker.
