The short answer
On the Amana A refrigerator family, a noise the cabinet did not used to make points at the mounts, because hardened rubber under the compressor is what turns an old but healthy machine loud. The brand-generic article puts the condenser fan at the top of this symptom; on this platform it sits second, behind causes that are quicker to rule out.
What you observe on these models
- A drone that rises and falls with the compressor — Bearing or mounting noise rather than anything catching.
- A rhythmic tick or clatter from behind the cabinet — Keeping time with something turning, which is how a fouled fan announces itself.
- A noise that comes and goes with no pattern anyone can find — Often two lines touching, because they only buzz at one particular speed.
- NEAR MISS — the noise arrived with the cabinet getting warm — Then the noise is a clue to a cooling fault and that page ranks the causes differently.
Causes, most likely first on this family
- Compressor mounts, or the compressor itself — The first thing to rule in. 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.
- Condenser fan blade fouled, or its bearing worn — Second, and close behind the first. 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.
- Refrigerant tubing touching the cabinet or another line — Third. Two lines resting against each other buzz at one particular compressor speed and go quiet at others, which is why the noise seems to come and go without a pattern.
- Loose rear panel, drain pan or tubing touching the cabinet — Last on this list. 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.
Check in this order, and why
- Rock the cabinet gently and listen for a change — Start here. Vibration that changes when the cabinet is loaded differently is mounting rather than mechanism.
- Listen at the back while the compressor runs — Then this. A tick that keeps time with the fan, or a drone that rises with it, is identified from the room without a tool.
- Look for two lines resting against each other at the back — Third. Separating them by hand, with the power off, either fixes the noise immediately or rules the cause out.

Safety
Unplug the appliance or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. Leave the door switch wired as it is — it cuts power to a fan for a reason, and defeating it puts a hand near a blade that is still live.

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.
