Most noise from an Electactic refrigerator comes from how it is standing rather than from anything failing inside it. The ranking below is ordered for this class of unit.
The symptoms, including the ones that mean something else
- The machine has behaved this way since it was fairly new — A platform built to a price tends to show its weak points early rather than after years.
- The noise stops the moment the freezer door opens — That points straight at a fan behind the freezer wall.
- NEAR MISS: the noise comes with water under the unit — That is a drain or supply fault and it has its own page.
Causes in order of likelihood on this brand
- The unit is not level, or it is touching a wall or a cabinet — A refrigerator transmits every vibration it makes into whatever it touches. Ranked first on an Electactic refrigerator: cabinets and frames at this price arrive with soft feet and light panels, so levelling and clearance account for more complaints than any component does.
- A loose drain tray, or something fallen behind the unit — The evaporation tray underneath buzzes when it is loose or overfull, and cardboard, a fallen magnet or a stray bottle behind the unit will buzz very convincingly indeed. Ranked second on an Electactic refrigerator: the drain path is short and traceable, so it is cleared before anything that needs a part.
- A unit working hard in a hot or enclosed spot — Fans speed up and the compressor runs far longer when the air around the unit is warm or cannot move. Ranked third on an Electactic refrigerator: the surrounding air decides how hard the machine has to work, so the environment is settled first.
- A fan blade catching on frost or debris — A blade that has bent, iced up or picked up a scrap of packaging ticks or rattles. Ranked fourth on an Electactic refrigerator: this is the cause that most often masquerades as an expensive fault.
What to check first, second and third
- Rock the unit corner to corner and check every foot is carrying weight — Anything that moves is a cause before anything inside the cabinet is.
- Look underneath and behind for a tray or an object that can be moved by hand — A tray that rattles when nudged is the noise you came for.
- Feel the air at the back of the unit and check what it is boxed in by — A unit in its own warm air runs longer and therefore sounds constant.
The checks you can make yourself
- Level the unit front to back and side to side, then pull it clear of the cabinets. Get a second person before you pull the cabinet out or tilt it. — Leave the clearance the manufacturer asks for at the back and the sides.
Tools: spirit level, adjustable spannerAbout 20 min
- Seat the drain tray properly and clear anything that has fallen behind the unit — Check the floor behind it as well as the back panel itself.
Tools: torchAbout 15 min
- STOP HERE if the next step needs a meter on live terminals or a panel off — That is where an owner check ends and a service call begins.
Safety first
Safety
Unplug the unit or switch off its breaker before removing any panel: a capacitor can hold a charge after the power is off. Refrigerant work is licensed work, so never cut, bend or solder the tubing, and never run the unit with the sealed system open. A loaded refrigerator is heavy and top-sided, so get help to move it rather than walking it on a corner.
When this becomes a service call
Call when the unit is level, clear of the cabinets and still making a noise that rises with the compressor, because what is left is behind a panel. Call sooner if the noise is a metallic scrape or a knock at start-up, and call immediately if it comes with a burning smell.

The scope of this page
This page is written for the Electactic refrigerator as a class, not for one family or model line. Shelf layouts, defrost-control types, fan placement and part numbers all change from build to build and are deliberately not here. Where a family- or model-specific page exists for your unit, it is the more specific answer and the one to read first.
