The short answer
A 4w10j50 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
- Occasional loud bangs with no pattern — Switch the ice maker off for a day to test it.
- 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.
- NEAR MISS — the noise came with the cabinet warming — Check the temperature before chasing the sound.
Causes on the 4w10j50 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. A worn fan bearing whines or chirps and gets worse as the motor warms. 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 — The condenser fan only runs when the compressor does, so a noise that starts and stops with the hum is almost certainly this one. Look before you order anything.
- 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. It follows no rhythm you can predict, which is what makes it alarming.
- A compressor on failed mounts — Rubber mounts harden with age and stop isolating the compressor, so a unit that was quiet for years becomes a drummer. The noise is a low drone rather than a rattle, and it is present whenever the compressor runs.
Check in this order, and why
- 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.
- Press a flat hand on each panel in turn — Resonance stops under a palm; a bearing does not care. Work the doors, the kickplate and the top.
- 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.
- 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.
