Clean condenser coils: Dirty coils can impede the fridge's ability to dissipate heat, causing it to overcool
Dirty condenser coils are a common culprit behind a refrigerator's inability to maintain the correct temperature. The coils, typically located at the back or bottom of the fridge, play a crucial role in dissipating heat generated during the cooling process. When they become clogged with dust, debris, or pet hair, the fridge's efficiency plummets, leading to overcooling and potential freezer burn.
To clean the condenser coils, start by unplugging the refrigerator and removing any items from the back or bottom area. Use a soft brush or vacuum cleaner with a brush attachment to gently remove loose debris from the coils. Be careful not to damage the delicate fins of the coils, as this can further impede heat dissipation.
