The short answer
Amana AQ owners usually report this as "it runs all the time and nothing is cold", and that phrasing is the diagnosis. The matrix on this page is the definitive list for this family: one model number. A unit chasing a setpoint it cannot reach has lost airflow, not refrigerant, and the order below reflects that.
Symptoms on these models
- The compressor never shuts off — It runs continuously without reaching setpoint — the same fault seen from the other side.
- 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.
- 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 — Silence plus warmth is a start-device or compressor fault, and the checks on this page assume neither.
Causes, most likely first on the AQ line
- Evaporator fan motor failure — First here, because the matrix on this page covers a single build rather than a span of generations — wear on a continuously-loaded motor is the failure that does not care which generation of the family you own.
- Stalled defrost cycle icing the evaporator — Second because it produces the identical complaint with one visible difference: a stalled defrost leaves a slab of ice on the rear panel, and a dead fan leaves the coil clean.
- Air damper or door seal leaking into the cabinet — Third because it explains the split case — one compartment cold, the other not — which neither of the causes above does on its own.
- Sealed-system or compressor fault — Last, deliberately. The three causes above are cheaper, commoner and checkable without tools; this one ends in a quote rather than a repair.
What to check first, second, third
- Hold the freezer door switch in and listen for moving air — This is the single point that feeds both compartments, so it goes first.
- Look behind the freezer rear panel for ice — A clean coil with a dead fan and an iced coil with a live fan are two different repairs, and this look separates them.
- Check the damper between the compartments — If the freezer is cold and the fresh-food side is not, the air path between them is the fault and neither fan nor defrost is to blame.
- Leave the condenser until last — A dusty coil makes a marginal system worse rather than producing a completely warm cabinet on its own.
Safety first
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.

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.
