Overview

• LG and Bosch told GameStar that exterior magnets do not affect cooling performance, power consumption, or appliance lifespan.
• Consumer group OCU and energy provider Endesa likewise report that the magnets’ fields are far too weak to interfere with a refrigerator’s technology.
• Experts say that even with many magnets attached there is no measurable impact on efficiency.
• The only caveat cited is mechanical: a heavy load of magnets can stress door hinges over time, which does not change energy use.
• To cut electricity use, guidance highlights 7 °C in the fridge and -18 °C in the freezer, brief door openings, a cool location with wall clearance, regular defrosting and vent cleaning, sound door seals, and storing only cooled food.
