The short answer
On the Amana 5w5ag50 refrigerator family, a noise the cabinet did not used to make points at the water side, because a buzz that coincides with a fill is telling you about the supply rather than about the appliance. 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 buzz lasting a few seconds, a few times a day — Timed to a fill, which is the water side talking rather than the machine.
- 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.
- NEAR MISS — the sound only happens when a door closes — Hinges and closers, not machinery.
Causes, most likely first on this family
- Water inlet valve buzzing on fill — The first thing to rule in. A valve that buzzes loudly is usually being fed too little pressure or is partly blocked. The noise is a symptom of the water supply rather than of the valve itself.
- 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.
- Ice maker fill and harvest, which is normal cycle noise — Third. A buzz then a clatter, a few times a day, is the maker working. Owners who have just started using the ice line often report it as a new fault, and no part is at fault.
- 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
- Listen for whether the buzz coincides with a fill — Start here. A buzz tied to a fill is the water supply talking; a buzz with no fill is not.
- 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.
- Time the noise against the ice maker — Third. A buzz then a clatter, a few times a day, is the maker working and needs no attention at all.
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. Refrigerant work is licensed work. Do not cut, braze or vent a sealed system, and do not run a unit that is leaking oil at the compressor.

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.
