What this means on these models
When the AZM line loses cooling but the compressor still cycles, the fault sits between the evaporator and the cabinet air, not in the refrigerant circuit. The model matrix on this page lists one model number under this family badge. That is why the check order here starts at the air path and ends at the compressor, which is the reverse of what most owners assume.
Symptoms on these models
- A sheet of frost on the freezer rear wall — Ice forms a slab across the back panel instead of a thin even coat — the tell that airflow has already stopped.
- The fresh-food side warms before the freezer does — On a single-evaporator cabinet the fresh-food side is fed by air from the freezer, so it loses temperature first.
- 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 — Beads of water on the underside of shelves and on the door liner, which is the cabinet sitting above its dew point.
- NEAR MISS — the unit is silent and nothing is cold — That is a no-power, start-relay or compressor fault and it is a different page; this one assumes the unit runs.
Causes, most likely first on the AZM line
- Stalled defrost cycle icing the evaporator — Ranked first on the AZM line: this family is a tight one — one model number under one badge and a defrost circuit degrades gradually rather than failing outright, so the ice builds over weeks while the owner notices only the warmth.
- Evaporator fan motor failure — Second because it is the cause that leaves no evidence. A dead evaporator fan gives you a clean coil and a warm cabinet, and the only way to catch it is to listen for the fan while the door switch is held.
- Condenser coil or condenser fan choked — Third because it is an installation fault rather than a component fault. A coil packed with dust behind a unit pushed hard against a wall degrades cooling on any cabinet, and nothing about the models in the matrix changes that.
- Sealed-system or compressor fault — Last, and that ranking is the whole point of the order: it is the least common of the four and the only one that is not an owner fix. Reaching for it first is how people replace a working compressor.
The check order on these models
- Hold the freezer door switch closed and listen — A fan you can hear removes one of the two likeliest causes immediately, and it needs nothing but a hand.
- Take the bottom basket out and look at the rear panel — A solid sheet of ice rather than a light dusting tells you the defrost circuit stopped working weeks ago.
- Move the unit out and put a hand near the condenser — Trapped heat and a mat of dust are a slow degradation rather than a sudden failure, which is why they come third.
- Check the temperature the cabinet actually holds — Put a thermometer in a glass of water on the middle shelf overnight; a reading that never falls tells a technician far more than a control display does.
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. Do not defeat or tape the door switch to keep the fan running while you work, and do not thaw an iced evaporator with a heat gun or a knife — the tubing behind that ice punctures easily, and a punctured sealed system turns a small repair into a replacement.

Where owner work stops
The condition on these models is simple: if the next step needs gauges, a meter or the evaporator exposed, it is a service call. Everything before that point is a look and a listen. Do not run a cabinet that trips its breaker in the hope of keeping food cold — it will not, and the fault is electrical.
