Refrigerator Door Not Sealing — How to Fix the Gasket
A refrigerator door that doesn't seal lets warm, humid air in — driving up your power bill, causing frost and condensation, and making the fridge run constantly. The fix is usually cleaning or replacing the gasket.
Test the Seal
Close the door on a dollar bill (or a piece of paper). If it slides out easily, the seal is weak at that spot. Test all around the door. You can also look for condensation, frost, or a door that swings open slightly on its own — all signs of a bad seal.
1. Clean the Gasket First
Often the gasket just has food, syrup, or grime preventing a good seal. Wipe it thoroughly with warm soapy water, getting into the folds, and clean the surface it presses against. Rub a thin film of petroleum jelly or food-safe silicone on the gasket to help it seal and stay supple.
2. Check Door Alignment and Hinges
A door that sags from a loose hinge or an overloaded door shelf won't seal evenly. Tighten the hinge screws and don't overload the in-door shelves. A slightly sagging door can sometimes be adjusted at the hinge.
3. Replace a Worn Gasket
If the gasket is cracked, torn, hardened, or permanently deformed, replace it. Gaskets are model-specific (match your model number) and most press or screw into the door — a moderate DIY job. A new gasket restores the seal and cuts energy waste.
