The short answer
When the AU refrigerator family will not cool, the fault is usually in the path the cold air takes rather than in the machine that makes it. This family is one model number, which makes the scope of this page unusually clear. Work the path from the door inwards and the expensive cause is the one you reach last, not first.
The observations that separate this fault from its neighbours
- The thermometer disagrees with the display or dial — A control reading its sensor wrongly, or a sensor that has lost contact with its mount. Trust the thermometer, not the panel.
- The cabinet is warm while the compressor is clearly running — You can hear or feel the unit working, yet nothing inside comes down to temperature. That pairing rules out most no-power faults before you touch anything.
- The unit never cycles off — A compressor that runs without a break is a compressor that never reaches its cut-out point. Continuous running is the same fault seen from the control side.
- Food at the door is spoiling faster than food at the back — A door-side gradient usually means the seal is losing cold air rather than the cooling system losing capacity.
- NEAR MISS — the cabinet is silent and nothing is cold — Silence changes the question entirely: that is a no-power, start-device or control fault, and it belongs on a different page.
Ranked causes for these models
- The internal air path blocked by loading — Ranked first because the complaint is usually partial — one shelf or one compartment is warm — and a partial failure is a distribution problem by definition.
- Door seal and door alignment — Second, because on cabinets of this build the door carries a large share of the insulation, and a seal that has taken a set at one corner is visible if you look along the door edge with the door almost shut.
- Frosted evaporator or a stalled defrost — Third, and its position is the useful part — finding ice does not end the diagnosis, it starts the question of what put the moisture there.
- Fans and the condenser — Fourth. Fans and a dusty condenser are grouped here because they share a symptom and a fix boundary: you can hear the first and clean the second, but both live behind a cover.
- The sealed system — Last. Reaching this point should mean everything above it has been ruled out, not that the cabinet is old.
Check in this order, and why
- Listen for the pattern rather than the presence of running — Steady running, a click every few minutes, or short bursts — the pattern names the suspect before anything is opened.
- Put a thermometer in the cabinet and leave it — What the cabinet holds is the measurement that matters; the dial setting is only what it was asked to hold.
- Check the seal and the way the cabinet is loaded — Two owner-side causes that are often found together and are fixed in the same few minutes.
- Stop at the sealed system — Anything past this point is licensed work, and the diagnosis above is what a technician will want to hear first.
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. Leave the door switch wired as it is: it cuts power to the internal fan for a reason, and defeating it puts a moving blade in reach of a hand. Anything on the sealed system is licensed work; do not open refrigerant tubing. A refrigerator holds food safely at 40 °F (4 °C) or below, and a freezer at 0 °F (−18 °C) or below. If the cabinet has been above that and you do not know for how long, the safe assumption is the worst one. Keep the door closed while you work — every opening costs cold you cannot put back quickly.

Where owner work stops
Call when the cabinet has been checked from the outside and is still warm, or the moment the fault is on the sealed system. A technician will want to know three things you can collect for nothing: whether the compressor runs steadily, whether air moves at the vent, and whether there is ice at the back of the freezer section. On the AU refrigerator family those three answers usually decide the repair before anyone arrives.
