A damaged gasket can let cold air escape, causing your refrigerator to work harder and use more energy.
A simple test is to close the door on a sheet of paper. If the paper slides out easily without resistance, the seal may need adjustment or replacement.
Bonus Tip: Keep the Rubber Soft
After cleaning and drying, some appliance experts recommend applying a very thin layer of food-grade silicone lubricant (made for rubber seals) if the gasket is becoming dry or stiff. Avoid using petroleum jelly unless your refrigerator manufacturer specifically recommends it, as petroleum-based products can damage some types of rubber over time.Bathroom
