The short answer
On a WH refrigerator, abnormal noise or vibration is most often the speed the compressor has been told to run at, which changes the sound of a perfectly healthy unit more than any fault on this list. The causes below are in likelihood order, cheapest first; working down that order costs less than starting with the part that sounds most alarming.
What you actually observe
- A loud run that settles down after a while — Speed, not damage: a compressor asked to pull down quickly is louder than one holding temperature.
- A buzz or hum that changes when the unit is nudged — Transmission through the surface, not a fault inside the cabinet.
- A rattle that comes and goes with the compressor — Something loose that only resonates at the compressor's frequency.
- Gurgling and light ticking after the compressor stops — NEAR MISS: normal refrigerant settling in the sealed system, not a fault at all.
- Body: Where a step below depends on which WH listing you own, the table above is the reference; nothing here is written from a model outside it.
Ranked causes on these WH models
- 1. The condenser fan and what is near it — Dust builds unevenly on a blade too, and an out-of-balance fan hums at a pitch nothing else in the unit produces. It moves up on WH because the three listings grow the cabinet without growing the vent face in proportion, so the largest of them is the tightest for air.
- 2. The surface underneath it — A small cabinet with a compressor in one corner is a loudspeaker for its own machinery. On a thin floor, a drawer slide or a hollow locker, the same unit that was quiet on concrete becomes intrusive. Second on WH: it takes longer to confirm than the cause above it, and it rarely arrives without warning.
- 3. The speed the compressor has been set to run at — Before any part is suspected, it is worth knowing whether the unit is in its loudest legitimate state. A quiet mode and a settled load answer many noise complaints.
- 4. The rubber grommets under the compressor — The compressor floats on small rubber mounts. Once they harden or compress, its vibration reaches the shell directly and the unit gets louder every year without any single failure.
Check in this order on the WH platform
- 1. Look into the vent face for anything resting on the blade — A tick that follows the compressor is nearly always this.
- 2. Lift it clear of the surface briefly while it runs — If the noise changes or disappears, the surface was the amplifier.
- 3. Check which mode the panel is in — The loudest legitimate state should be known before any part is suspected.

Safety
Isolate before investigating: unplug the appliance or switch off its breaker, and treat a capacitor as charged even after power is removed. Keep hands out of a running fan, and never pack material against a compressor to damp it, because what it is actually doing is blocking the airflow that keeps it alive. The WH roster covers three listings, WH38 through WH58, and what follows is common to all of them unless a step says otherwise.

When to call a technician
Call for a metallic knock that rises with load, or for a click every few minutes that never turns into a run. Both are the compressor and its start circuit, and neither gets better with time. No two WH listings share a base number, so each one in the table is a distinct machine rather than a revision of its neighbour.
