The short answer
An Amana M makes a small number of noises in normal operation and a small number that mean something. The matrix on this page is the definitive list for this family: one model number. 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 you hear, and where from
- 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 chirp, squeal or grind from inside the freezer — A sound that vanishes the instant the freezer door opens, because the door switch cuts the evaporator fan.
- 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 — A compressor on tired mounts transmits into the floor, so the cabinet appears to get louder without the compressor changing at all.
- A knock or thump on start and stop — Tubing that has shifted onto the cabinet transmits every compressor start as a single knock.
- 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.
Causes, most likely first on the M line
- Evaporator fan blade fouling ice or a worn fan bearing — First on the M line because this fan runs whenever the compressor does, in the coldest and wettest part of the cabinet, and its blade sits close enough to the coil that any frost build-up reaches it.
- Condenser fan obstructed or bearing worn — Second, and easier to confirm than the first — pull the unit out, look, and the obstruction is usually visible.
- Compressor mounts and cabinet levelling — Third: a hum that has grown without changing pitch is normally transmission through tired mounts or an unlevel cabinet, not a failing motor.
- Compressor or start relay fault — Last: a relay clicking on a cycle of a few minutes with no cooling is distinctive, and a genuinely noisy compressor is rarer than any of the three above.
What to check first, second, third
- Open the freezer and hold the door switch in — If the noise stops when the door opens and returns when the switch is held, it is the evaporator fan and nothing else. This is first because it is decisive and needs no tools.
- Look for frost on the freezer rear panel — A blade ticking against ice and a worn bearing sound similar; the ice tells you which, and it changes the repair.
- Pull the cabinet out and watch the condenser fan turn — Obstructions here are usually visible before anything is unscrewed.
- Check the cabinet is level and not touching the surround — Last, because it explains a noise that has grown rather than one that appeared, and it is an adjustment rather than a repair.
Safety first
Safety
Isolate the appliance at its breaker or unplug it before any panel comes off — a capacitor can hold a charge after the power is off. The freezer door switch is a guard, not an inconvenience: if you hold it in to test the fan, keep both hands away from the blade and release it before reaching inside.

Where owner work stops
The condition is what the fix turns out to be. An adjustment — levelling, clearing something that fell in, moving the cabinet off a wall — is owner work on these models. A part is not. A repeating click with a warming cabinet should be booked the same day rather than monitored.
