What this means on these models
An Amana AQ makes a small number of noises in normal operation and a small number that mean something. The model matrix on this page lists one model number under this family badge. The useful distinction is not loud against quiet but where the sound comes from and whether it tracks the compressor cycle, and that is how the ranking below is built.
What the owner reports
- A rattle or buzz from the back of the cabinet — A buzz behind the cabinet that starts and stops in step with the compressor, which places it in the machine compartment.
- A clicking that repeats every few minutes — A compressor start relay dropping out and retrying makes an even, repeating click with no cooling to show for it.
- A buzz or hum that has become noticeably louder — Hum that you feel through the floor more than you hear in the room is usually mounting or levelling, not the motor.
- A knock or thump on start and stop — One thump as the compressor starts and one as it stops is a contact point, not a failure.
- Gurgling, popping or a running-water sound — These are normal on every cabinet of this type and they get louder in a quiet room rather than in a failing appliance.
- NEAR MISS — the noise comes with a warm cabinet — Then the noise is secondary and the cooling failure is the page you want; fix the cooling and the noise usually goes with it.
Ranked causes for these models
- Condenser fan obstructed, unbalanced or worn — Ranked first on the AQ line because the matrix on this page covers a single build rather than a span of generations — the machine compartment is open to the room, it collects whatever the floor offers, and that is true of every model in the table below.
- Evaporator fan blade catching ice — Second, and it usually arrives with a frost build-up, so it is worth looking for ice at the same time.
- Tubing or a component contacting the cabinet — Third: a single knock as the compressor starts or stops is a contact point that has shifted, and it is a five-minute fix once it is found.
- Compressor mounts or the compressor itself — Last: mounts perish slowly and compressors rarely announce themselves, so this is a conclusion reached by elimination rather than a first guess.
The check order on these models
- Move the unit away from the wall and watch the condenser fan run — It is the quickest look with the least disruption.
- Check whether anything has fallen against the blade or the coil — Packaging, a pet toy or a loose drain tube account for a large share of sudden noises.
- Then open the freezer and hold the door switch closed — That moves the search to the other compartment and separates the two fans for good.
- Feel for vibration at the compressor and check the feet — Last: a hum transmitted through the floor is a mounting question, and it is answered by touch rather than by a part.
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. If you hold the freezer door switch in to test the evaporator fan, keep your fingers well clear of the blade: that switch exists to stop the fan when the door opens. Never run the cabinet with the machine-compartment cover off.

The service-call line
The condition is whether the fix is an adjustment or a part. Levelling, clearing debris and locating the sound are owner jobs on these models; replacing a fan motor behind the evaporator, a start relay or a compressor mount is a service call. A click every few minutes with no cooling should be booked the same day rather than watched.
