The short answer
On the 4w10g20 refrigerator this symptom is usually how the cabinet stands, because a machine that rocks on one foot turns ordinary running vibration into a noise the whole room hears. Every model number in the 4w10g20 family is the same platform at a different point in its production run, so read your full model number before ordering anything.
What you observe
- A dull rhythmic thud under load that has got worse over months — The one noise on this list that tends not to be anything cheap.
- A rattle or whirr from behind the machine that rises and falls — Tied to the compressor cycle, which puts it at the condenser end of the cabinet.
- A hard ticking that stops the moment the freezer door opens — The door switch cuts that fan, so the noise is inside the freezer.
- A hum that is louder in the next room than in the kitchen — Structure-borne vibration, which is mounting and levelling rather than a failing part.
- NEAR MISS — the noise is there and the cabinet is also warming — Noise plus a temperature problem is an airflow fault, and the cooling page is where that combination gets diagnosed.
Causes, most likely first on the 4w10g20 family
- Cabinet not level, or resonating against a floor or wall — First on this family. One short foot, a floorboard that flexes or a unit touching a wall at a single point converts a quiet hum into a buzz that comes and goes with the compressor.
- Ice maker filling and harvesting — Second on these models. It is worth naming because switching the maker off for a day is a free test that settles it completely.
- Refrigerant tubing touching the cabinet or another tube — Third. Tubes shift over years and after a house move, and two lines touching pass vibration into each other at a frequency the cabinet amplifies.
- Damper motor or a control relay clicking — Last of the four, and the one to reach for only when the others are clean. A grinding or repeated stuttering click is not, and that version belongs with the airflow faults rather than here.
- Body: A brand-generic article on this symptom starts with the condenser fan.
Check in this order, and why
- Rock the cabinet gently at each front corner and check the gap at the back — Any movement at a corner, or a cabinet touching the wall, is worth correcting before anything is dismantled.
- Switch the ice maker off for a day and listen again — If the noise disappears with the maker off and returns when it is on, no repair is needed.
- With the unit isolated, look for two tubes touching or a tube resting on the shell — A visible contact point is the answer; separating them is a technician job on the sealed side, so do not lever anything.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into a fan shroud — a capacitor can hold a charge after the power is off, and a fan can start without warning while power is on.

When to call a technician
Call when the noise survives the free checks — levelling, debris, loose panels and the ice maker switched off — because what remains needs a panel off. Call promptly for a grinding or metallic noise that is getting louder week by week rather than staying the same.
