The short answer
The AU roster records a single model, so nothing on this page has to be hedged across variants, and it is the only entry on that roster, so the rating plate confirms your cabinet in a single step. The useful distinction on these cabinets is between a freezer that is not cold and a freezer that is not cold enough. The second is the common case, it is progressive, and almost all of it is owner-diagnosable; the first is rarer and usually points at the start components or the sealed circuit.
What you observe on these models
- Frost building up thickly on the walls or the cold plate — A blanket rather than the usual light dusting.
- The compressor never cycles off — A cabinet that runs without pause has stopped reaching its set point.
- Moisture or ice at the lid or door line — Warm room air meeting cold cabinet air at a seal that is not closing.
- The outside of the cabinet is warm to the touch — Some warmth at the sides is normal on cabinets that use the shell to reject heat.
Causes, most likely first on the AU line
- Lid or door seal not closing — Ranked first on this roster: seals fail gradually, which is why the cabinet seems to have been fine until it suddenly was not; the leak has been growing for months.
- Condenser dirty or the cabinet boxed in — Ranked second on this roster: heat has to leave the cabinet somewhere, and a condenser choked with dust or a cabinet pushed tight against a wall gives it nowhere to go, so the machine runs continuously and still loses ground.
- Frost blanket on the cold surface — It ranks third here because it is both a cause and a consequence: whatever let the moisture in is still there after the frost is cleared.
- Loss in the sealed system — Ranked last on this roster: it becomes the likely answer only once the seal, the frost and the condenser have all been cleared and the cabinet still will not hold.
- Body: Where this ranking departs from the brand-generic order is condenser dirty or the cabinet boxed in, which moves up on the AU line because this roster is a single cabinet rather than a line, so the order is what that one machine makes likely and not an average taken across several.
Check in this order, and why
- Close the lid or door on a strip of paper and pull — Do it at several points around the opening. Anywhere the paper slides out freely is a leak, and that is where the frost will be.
- Clear the condenser and give the cabinet air on every side — With the power off, clean the coil or compartment and pull the cabinet clear of the wall. Then give it a day before judging.
- Look at the cold surface and measure the build-up by eye — A layer thick enough to hide the surface underneath is enough to explain the complaint on its own. Defrost fully and see whether the cabinet recovers.
- Have the circuit assessed rather than guessed at — This needs gauges and a licence. Reaching it is a result, not a failure, because it tells you the decision is repair or replace.
Before you open anything
Safety
Unplug the cabinet or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Never use a sharp tool to break frost off a cold surface: the tubing behind it is thin-walled, and a nicked tube turns a defrost into a replacement. A freezer holds food safely at 0 °F (−18 °C) or below, so move the load to a cooler with ice before you start rather than after.

When to call a technician
The owner side of this fault ends at the point a panel has to come off. Defrosting, re-seating a seal, clearing the condenser and giving the cabinet air are all yours and cost nothing. Anything behind a fastener, anything involving the control sensor, and everything on the sealed circuit is a service call.
