Warm up to your fridge.
The best way to maintain your refrigerator is simply to keep it clean, inside and out.
Clean under and behind your refrigerator regularly. Whirlpool Institute of Kitchen Science expert Lucinda Ottusch says it’s important to remove and clean the refrigerator’s base grill often to improve air flow to the appliance’s components. Ryan Huntley, of RepairClinic.com, says that the coils at the bottom or behind your refrigerator need regular cleaning so the coils can efficiently cool the unit.
