The short answer
On the Amana AMAW refrigerator family, a noise the cabinet did not used to make points at the machine compartment, because the loudest part of a refrigerator is behind it and that is where a new noise almost always starts. The brand-generic article leads the same way, but the places behind it are not the same here, and that is where a visit is won or lost.
What you observe on these models
- A rhythmic tick or clatter from behind the cabinet — Keeping time with something turning, which is how a fouled fan announces itself.
- A rattle that stops under a hand on the rear panel — Transmission through sheet metal, not a part that is failing.
- A chirp or scrape that stops when a door is opened — The door switch cuts one of the two fans, and that test costs nothing at all.
- NEAR MISS — the sound only happens when a door closes — Hinges and closers, not machinery.
Causes, most likely first on this family
- Condenser fan blade fouled, or its bearing worn — The first thing to rule in. The fan lives in the dirtiest part of the machine. Debris on the blade produces a rhythmic tick, a worn bearing produces a drone, and both get louder as the compressor gets hotter.
- Loose rear panel, drain pan or tubing touching the cabinet — Second, and close behind the first. Nothing has failed. A fastener has backed off or a pan has shifted, and the machine is simply transmitting the compressor vibration into sheet metal that used to be damped.
- Evaporator fan blade catching ice, or its bearing — Third. A blade clipping frost makes a chirp or a scrape that changes when the door is opened, because the door switch cuts the fan. That single test separates it from almost everything else on this list.
- Compressor mounts, or the compressor itself — Last, and the only one of the four here that is not owner work. Rubber mounts harden with age and stop isolating a vibration that was always there. A genuinely failing compressor is loud in a different way, with a knock rather than a hum.
Check in this order, and why
- Listen at the back while the compressor runs — Start here. A tick that keeps time with the fan, or a drone that rises with it, is identified from the room without a tool.
- Press on the rear panel and the pan while the noise is happening — Then this. If the noise stops under a hand, nothing has failed and a fastener is the whole repair.
- Open the freezer door and listen for the noise to stop — Third. The door switch cuts that fan. A noise that stops with the door open is inside the freezer and nowhere else.
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.

When to call a technician
Call once the free checks are clean and the noise is still there, because what remains is a fan bearing, a mount or the compressor, and all three want the cabinet moved. Call straight away if the noise arrived together with poor cooling or a hot smell, since then the noise is a symptom of something larger.
