How often should you dust refrigerator coils?
Reviewed
The short answer
every 6 months
Every six months. The coils at the back or underneath shed heat, and a layer of dust traps it against the metal.
A kitchen with pets or carpet fills them faster than that.
Where the heat goes
A fridge does not make cold; it moves heat out of the cabinet and releases it through the coils. Anything insulating that grille keeps the heat in the room it just left.
The motor answers by running longer cycles. Nothing looks wrong from the front.
Finding them
Older machines carry a black grille across the back panel. Newer ones tuck the coils underneath, behind a kick plate that pulls away by hand.
A vacuum with a brush head does the work in five minutes. A long thin radiator brush reaches what the nozzle cannot.
Air around the cabinet
Most makers ask for a few centimetres of clearance at the back and above. A fridge pushed flat into a recess recirculates its own warm air.
Common questions
Does this apply to integrated fridges?
Built-in units vent through a channel behind the furniture door, and that channel collects dust the same way. The panel usually lifts off without tools once the plinth is out.
What else is worth checking at the same time?
The door seal, and the drain hole at the back of the salad drawer. A blocked drain leaves a puddle under the crisper long before anyone connects the two.
