The short answer
Noise on a 4w5ij90 refrigerator is a locating problem before it is a repair problem. The generic Amana answer has to describe every cabinet layout at once; here the freezer, the machine compartment and the cabinet itself each produce a different family of sounds.
What you actually observe
- Pops and ticks on a regular interval — Note two consecutive times and compare them.
- A whine that rises as the unit warms up — A bearing gets worse with heat; resonance does not.
- A rattle you can hear from behind the cabinet — Look at the condenser fan before assuming anything.
- NEAR MISS — the noise came with the cabinet warming — Then the noise is secondary and the cooling fault is the page you want.
Causes on the 4w5ij90 listings, most likely first
- The evaporator fan hitting ice or a worn bearing — A fan blade clipping a frost ridge gives a regular ticking or a buzz that stops dead when the door opens, because the door switch cuts the fan. Ice against the blade sounds mechanical and expensive and almost never is. The long revision run above covers a lot of production, and the oldest listings in it reach this point first.
- A loose panel, grille or shelf resonating — A cabinet panel that has worked loose buzzes only at certain compressor speeds, which is why it sounds intermittent and maddening. A hand pressed flat on it while it buzzes settles the question instantly.
- Normal ice-maker cycle noise — The harvest cycle on the listings with an ice maker drops cubes with a bang and then refills with a hum, several times a day. It is loud, it is normal, and it is the noise most often reported as a fault.
- A cabinet out of level or rocking on its feet — This ranks high on a family shipped with adjustable front feet, because the adjustment is the thing that gets lost whenever the unit is moved. Level it, then listen again before suspecting a part.
Check in this order, and why
- Open the freezer door while the noise is happening — If it stops, you are in the freezer; if it carries on, you are not. Nothing else narrows the list this fast. Hold the switch in to confirm.
- Note whether the noise follows the compressor — A noise tied to the hum is in the machine compartment; a noise that ignores it is in the cabinet. Two observations are enough to establish the pattern; more tell you nothing new.
- Put a level on the cabinet and rock the top corners — Do this early: it is free, and a rocking cabinet makes every other noise louder than it really is. Adjust it at the front feet, since that is the only adjustment these cabinets have.
- Switch the ice maker off for a day — Only worth doing for bangs and fills, and it is conclusive when it is. Leave the bin in place while you test.
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. Never run the unit with the rear cover off to hear it better; the condenser fan is unguarded once that panel is away. Have a second person steady the cabinet if you have to tilt it.

When to call a technician
Tightening a rattling panel, levelling a cabinet and clearing debris from a condenser fan are owner jobs. A fan motor behind the freezer rear panel, and anything that has started at the compressor, is not. Call without waiting if the noise is a hard knock at start-up, or if the unit trips the breaker: a compressor struggling to start makes both noises.
