What this means on these models
Amana AZF owners usually report this as "it runs all the time and nothing is cold", and that phrasing is the diagnosis. Three model numbers carry this family badge, and the matrix on this page is the list. A unit chasing a setpoint it cannot reach has lost airflow, not refrigerant, and the order below reflects that.
Symptoms on these models
- The cabinet is warm but the unit is clearly running — The compressor hum is there and the cabinet light works; the air inside is simply not cold.
- A sheet of frost on the freezer rear wall — Thick, uneven ice across the back panel rather than the fine even coat a healthy cabinet carries.
- 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 — That is a no-power, start-relay or compressor fault and it is a different page; this one assumes the unit runs.
Ranked causes for these models
- Stalled defrost cycle icing the evaporator — First here because the matrix on this page covers only a handful of closely related models — a defrost heater or timer that is half-working still passes a casual inspection, and the frost slab it leaves is the most common single cause of this symptom.
- 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 depends on the room rather than the platform — a coil packed with lint behaves identically on every model in the table below.
- 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
- Listen at the freezer for the evaporator fan — Open the freezer and hold the door switch in. A fan you can hear rules out half of the two likeliest causes before any tool comes out.
- Look for a frost slab on the freezer rear panel — If the fan runs and the rear wall is iced over, the defrost circuit is the fault and the airflow is a symptom of it.
- Feel the condenser area for trapped heat and lint — Only worth doing once the two above are clean, because a choked coil degrades cooling slowly rather than killing it.
- 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 opening anything; a capacitor can hold a charge after the power is off. Empty the cabinet before moving it — a loaded refrigerator is heavy enough to injure someone on a hard floor — and keep the door switch intact rather than taping it closed to run a test.

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 AZF 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.
