Do you have the impression that your fridge closes less well than before? Don’t let the problem drag on. A damaged or poorly positioned gasket can allow hot air to enter and cause the temperature inside the appliance to vary. The result: less well-preserved food and an increased risk of bacteria proliferation.
How to check the condition of the refrigerator gasket
Before taking out the hair dryer, first check the seal. The test is very simple: slide a sheet of paper between the door and the refrigerator, close it, then gently pull it. If it comes without resistance, the seal probably no longer presses enough in this location.
Other signs may alert you: frost around the seal, a door that bounces or deformed rubber.
Start by cleaning the joint and its groove with a soft sponge, then dry them carefully. Dirt or poor positioning can sometimes be enough to prevent the door from closing correctly.
This detail also matters for food safety. As ANSES points out, the coldest zone of the refrigerator must be maintained between 0 and 4°C to slow down the multiplication of microorganisms.
Softening a fridge seal with a hair dryer: precautions
If the seal is not torn or loose, the hair dryer can sometimes restore its shape. The tip, relayed on September 12, 2025 by the Marmiton website, consists of gently heating the joint, from a distance, using regular movements along its entire length.
Once the rubber has softened, knead it gently with your fingers to help it return to its place. As it cools, it can better fit the contour of the door.
But there is no question of heating at all costs. Some manufacturers recommend against using a heat source on their joints. Before trying the trick, check the manufacturer’s recommendations. And if the seal is torn, detached or very damaged, replacement remains the best option.
A tight seal to better preserve food
A refrigerator isn’t just for keeping your food cold. It plays an essential role in their conservation and helps limit the multiplication of bacteria.
A defective seal can disrupt this cold chain. If the temperature rises too high, certain foods may become unfit for consumption without necessarily changing their smell or appearance.
The good reflex therefore consists of regularly checking the closure of the door and the condition of the seal. And, if you are in doubt about the temperature, place a thermometer in the refrigerator. In its coldest zone, it must remain between 0 and 4°C.
A little check that can avoid unpleasant surprises on the plate… and on the electricity bill.
