The short answer
A cabinet that will not cool on an AZB freezer usually comes down to heat it cannot reject: a dusty condenser or a cabinet pushed into a corner in a hot room loses capacity long before anything inside it breaks. The order that follows puts the likeliest and cheapest causes first, and it is the order worth working in rather than starting with the part that sounds most serious.
What you actually observe
- A thick frost layer has built up on the walls — Manual-defrost cabinets insulate themselves if the frost is left long enough.
- The contents at the top are softening first — Warm air enters at the top of a cabinet, so a seal problem shows there before anywhere else.
- The cabinet is running continuously and still warming — The compressor has power and is working; something is taking its output away.
- It is cold but water is collecting underneath — NEAR MISS: that is the water-leak reading of this cabinet, not a cooling failure.
- Body: Where a step below depends on which AZB listing you own, the table above is the reference; nothing here is written from a model outside it.
What causes it on the AZB platform, in likelihood order
- 1. The seal around the opening — A gasket is a consumable. A seal fault is cheap, common and easy to prove with a sheet of paper, which is why it sits at or near the top of every ranking for this symptom. The seal ranks this high on AZB because with one listing there is one door line and one gasket profile, and its condition is the whole variable.
- 2. Frost build-up acting as insulation — It is the only cause here that reverses itself completely for free: empty, defrost, dry, restart, and see what the cabinet actually does. It comes second because the check above it costs nothing, where this one usually means moving the machine.
- 3. Heat rejection choked with dust — The condenser has to throw heat into the room. Under a blanket of dust and lint, or pushed hard against a wall, it cannot, and the cabinet loses capacity across the board.
- 4. The start relay and overload protector — It ranks high because it is common and cheap, and because its symptom is unmistakable once it has been named.
The order to work in on this platform
- 1. Shut the door on a sheet of paper at several points and pull — Drag everywhere is a good seal; a free slide anywhere is where the warm air is getting in.
- 2. Look at the wall thickness of the frost before anything else — A coated cabinet has to be cleared before any other reading is trustworthy.
- 3. Feel the condenser area and look for dust and clearance — A hot outside and a warm inside is one fault, not two.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. A loaded freezer is heavy and top-heavy once the door is open, so never tip one to reach a condenser, and never chip frost with a blade because the evaporator tubing is directly behind it. The AZB roster is a single listing, AZB33X20D*, so everything here applies to one build rather than to a range.

When to call a technician
The line is the sealed system and the compressor. Seals, frost, dust and clearance are all owner work; refrigerant is licensed work, and a compressor that runs smoothly while the cabinet sits near room temperature has crossed the line.
