The short answer first
On the 4w3in62 refrigerator this symptom is usually the condenser fan, the only fan on this platform that runs in a dusty, open space where things can reach it. The 4w3in62 family is one platform carried across a run of revisions, and the trailing digits of the model number are what separate them: the fault set is shared, the part numbers are not.
What an owner actually sees
- 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 4w3in62 family
- Condenser fan hitting debris or running on a worn bearing — Top of the list here. A dry bearing in the same fan gives a steadier drone that gets worse over months and is loudest from the back of the machine.
- Refrigerant tubing touching the cabinet or another tube — Second here. 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 — Third on this platform. A grinding or repeated stuttering click is not, and that version belongs with the airflow faults rather than here.
- Defrost sizzle, water boiling off and normal expansion noises — Fourth: possible, but not where to start. Every cabinet with automatic defrost hisses when water hits the warm part of the coil, and every one gurgles for a minute after shutdown.
- Body: A brand-generic article on this symptom starts with the condenser fan, and so does this one. What changes below it is the order: the refrigerant moves up on these models, because a platform carried across this many revisions accumulates its failures in the parts that were never changed.
The order to work in
- Pull the unit out, isolate it and look at the condenser fan and its shroud — Debris against the blade, or a blade that will not spin freely by hand, is the whole diagnosis.
- 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.
- Time the clicks against a watch for a few minutes — Evenly spaced, single, soft clicks are the machine working.
Safety first
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.

Where the owner fix stops
Call promptly for a grinding or metallic noise that is getting louder week by week rather than staying the same. Any noise coming from the sealed side, or any tubing found touching, is a technician job and not something to bend back by hand.
