The short answer
A 4w5ij21 cabinet that has developed a new noise is usually telling you about a bearing, a blade or something loose against a panel. Where the brand-generic article ranks the compressor high, this one ranks it low: on these listings it is rarely the part that starts making noise first. Locate the noise before you look up any part.
What you actually observe
- The noise stops the moment the freezer door opens — The door switch cuts the evaporator fan, so this all but names the part.
- The noise starts and stops with the compressor — Anything tied to the hum is in the machine compartment rather than in the cabinet.
- The floor carries the sound into the next room — A rug under the front feet changes it if it is.
- Occasional loud bangs with no pattern — Switch the ice maker off for a day to test it.
Causes on the 4w5ij21 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 short revision run in the table above means these units left the line close together, so they wear at much the same rate.
- The condenser fan fouled by debris — A blade catching lint, a cable tie or a fallen label rattles in bursts that follow the compressor rather than the door. It is at the back or underneath and it is usually visible from the floor.
- A cabinet out of level or rocking on its feet — A unit resting on three of its four feet transmits every compressor vibration into the floor, and a timber floor amplifies it.
- Normal ice-maker cycle noise — Ranked here because on this family it is the most frequent cause of a call that needs no repair at all.
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.
- Look at the condenser fan from the floor — You are looking for debris against the blade and for dust loaded on one side of it. Switch the power off before reaching anywhere near the blade.
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. Do not reach into a fan to stop it or to feel for a blade: the freezer fan restarts the moment the door switch is released. A refrigerator is heavier than it looks with the doors loaded; empty it before you walk it out from the wall.

When to call a technician
The line on these models is the rear freezer panel and the machine compartment cover. Outside those, the causes are debris, fixings and levelling. Behind them, the parts are live, cold and awkward to reach, and the diagnosis needs the unit running with the panel off.
