Start here
Most new refrigerator noises come from something that moves rather than from the sealed system: a fan, a roller of ice, a cabinet that is rocking. On a Galanz refrigerator the order below is what a technician works through, because this is a high volume value build with simple hardware, where the parts you touch every day are the parts that wear. Where the noise changes when you open a door, you have already narrowed it to one compartment.
What you actually observe
- A whirring or grinding that changes when you open the freezer door — The door switch cuts the evaporator fan, so a noise that stops when the door opens is coming from that fan.
- The cabinet is compact and is usually filled to its limit — A small cabinet with small vents is unforgiving about loading, and loading is free to change.
- NEAR MISS: a hum with a click every few minutes and no cooling at all — That is a start relay or compressor fault, and it belongs on the page for a unit that is not cooling.
The causes, most likely first on this brand
- Water running to the drain pan under the cabinet — A gurgle or trickle after the unit stops is the drain doing exactly what it should, unless the pan itself has come loose. Ranked first on a Galanz refrigerator: the drain here is short, simple and unheated, and it blocks in a way that a more elaborate drain would not.
- Debris against the condenser fan behind the plinth or at the back — A cardboard strip, a bag or a dust mat at the lower fan makes a slapping noise that is easy to find and quick to fix. Ranked second on a Galanz refrigerator: the cabinet is compact and the vents are small, so anything in front of them matters immediately.
- A fan blade fouling ice, or a fan bearing that has worn — Both fans run for hours a day. A blade catching frost makes a harsh chatter; a dry bearing makes a whine that rises and falls with the cabinet. Ranked third on a Galanz refrigerator: the motors are small and simply mounted, so a failing one announces itself early.
- A cabinet that is not standing level or square — A unit rocking on one foot turns every compressor start into a knock, and it sends the drain water the wrong way at the same time. Ranked fourth on a Galanz refrigerator: a light cabinet on an uneven floor rocks, and a rocking cabinet is noisy and drains badly at once.
Check in this order, and why this order
- Look at how the cabinet is loaded before suspecting any part — How the cabinet is loaded changes what it is able to do, and loading is the one variable that is free to change.
- Open the freezer door and see whether the noise stops — That single test separates the evaporator fan from everything else in the cabinet.
What an owner can safely check
- Move packing clear of every vent and the fan grille, then run it for a day — Leave a real gap at each vent rather than a token one.
About 15 min
- Set the front feet or rollers so the cabinet stands firm and tips back very slightly — A cabinet that does not rock is quieter and drains correctly, and the adjustment takes minutes.
Tools: adjustable spanner, spirit levelAbout 15 min
- STOP HERE if the next step needs a meter on live terminals or a sealed panel off — That is the line where an owner check ends and a service call begins.
Before you open anything
Safety
Unplug the refrigerator or switch off its breaker before reaching behind the plinth or inside the freezer rear panel, because both fans start without warning and a capacitor can hold a charge after the power is off. The cabinet is heavy and rolls awkwardly, so get help to move it and mind the water line behind it.
When to call a technician
Call once the cabinet stands firm, the grille is clear and the ice is gone and the noise is still there, because the next steps are a fan replacement behind a sealed panel or a compressor diagnosis. Call at once for a loud metallic grinding from the compressor area or any noise that comes with a burning smell, and switch the unit off first.

What this page does not cover
This page covers the Galanz refrigerator as a class rather than one family or model line. Fan part numbers, panel fixings, roller types and compressor mounts differ from build to build and are deliberately not here. Where a family or model page exists for your cabinet, it is the more specific answer and the one to read first.
