The short answer
Noise is one of the few faults where listening carefully costs nothing and narrows the field almost completely. Where the sound comes from — freezer, back, base — matters more than what it sounds like. Across the REF line the useful discriminator is location: a noise from the freezer compartment and a noise from behind the machine are never the same fault, whatever they sound like through a closed door.
What the noise sounds like
- A rattle or vibration that comes and goes — Something loose, something touching something else, or the whole cabinet resonating against a wall or an uneven floor.
- A repetitive click every few minutes — A click every few minutes is a control doing its job. A click with a cabinet that has gone warm is worth reading differently.
- A knock or thump from low down at the back — The compressor area. A rhythmic knock from there is the one sound on this page worth acting on quickly.
- NEAR MISS — The noise is there but the cabinet has also gone warm — Noise together with a cabinet that is no longer cold usually means the noisy part is the part that has stopped working. Solve the temperature first.
What is behind it, ranked
- The ice maker cycling — Fill valves hammer, augers grind and ice drops into a bin with a bang. All of that is normal and all of it is louder in a quiet kitchen at night. It goes first because if it is not this, the rest of the list is much shorter. This is the departure from the brand-wide ranking: the ice maker cycling moves ahead of the condenser fan at the back or under the base on the REF models because it is confirmed by ear before anything is moved.
- The evaporator fan inside the freezer — A failing evaporator fan motor is the most common source of new noise in a refrigerator, and it is the one sound that changes the moment the freezer door is opened.
- The cabinet itself vibrating against floor, wall or contents — This costs nothing to test and nothing to fix, which is why it belongs near the top of any noise list rather than at the bottom.
What to check first, and why
- First — switch the ice maker off for a day — A night without the ice maker removes an entire family of bangs, whirs and hammering from the investigation.
- Second — open the freezer while the noise is happening — If the sound stops or changes the instant the door opens, it is the evaporator fan: the door switch has just cut its power. That one test separates the inside of the cabinet from the outside.
- Third — rock the cabinet and clear what is touching it — Rock the cabinet by a corner and listen. A machine that moves at all is a machine that can rattle against whatever is next to it.
Power off before panels come off
Safety
Unplug the refrigerator or switch off its breaker before any cover comes off, and remember a capacitor can hold a charge after the power is off. Never hold the freezer door switch in to keep a fan running while your hands are near the blade, and do not chip ice off a fan with anything metal — the tubing behind it punctures easily.
When to call a technician
The line is the inner panel. Levelling, clearing, vacuuming and switching the ice maker off are owner jobs; removing the freezer rear panel to reach a fan motor is not, because it is done with the machine live and the tubing behind it is unforgiving.
