The tight seal on a refrigerator door is what keeps contents cold and prevents spoiling. The gasket seal is the rubber strip on the door that contacts the refrigerator unit. When the seal becomes loose, food poisoning may result. If the gasket seal is coming loose or is weakened, the gasket should be replaced. This project is a little tricky but it can be done as long as patience is exercised.
You will need:
Step 1: Purchase a gasket that is an exact fit to the door. To make it pliable, soak it in a sink filled with hot water.
Step 2: Use the level tool to ensure that the refrigerator is level.
Step 3: Find a nut driver that fits the screws that anchor the old gasket into place. Begin your work at the top outside corner. Fold back the old gasket and partially loosen all screws along half of the side and top. Make sure you do not loosen the screws completely. The screws anchoring the gasket also hold together the insulation and inside panel.
Step 4: Pull out the old gasket.
Step 5: Attach the new gasket, pushing it underneath the metal retainer. Tighten the screws after you complete a section. Follow this process as you replace each section.
Step 6: Close the refrigerator door and check for any gaps. The new seal should be smooth and straight around the door.
Step 7: Look for any gaps between the frame and the gasket. If there are any, the door may have warped. This can be fixed by loosening the screws and then twisting the door a bit. Repeat as necessary until the door is straight.
Step 8: Place a flashlight into the refrigerator, point it toward the front opening, and shut the door. Turn off the lights in the room. No light should be visible from the interior of the refrigerator.
Step 9: If you have a separate freezer door, the same process can be used when its gasket needs replacement.
