According to European appliance manufacturer Beko, extended periods of hot weather can significantly impact refrigerator efficiency, especially if the door seal is damaged or worn. This is a common reason refrigerators struggle to maintain a stable temperature.

"A worn door seal can prevent the door from closing properly, allowing cold air to escape and outside heat to enter, forcing the compressor to work continuously to compensate," said Salah Sun, Beko's head of product management.

This constant operation significantly increases energy consumption. Data shows that a refrigerator with a faulty seal can use up to 30% more energy. This not only raises electricity costs but also wears down the compressor, reducing the appliance's lifespan. Additionally, a leaky seal can cause excessive frost buildup and temperature fluctuations, leading to faster food spoilage. Higher outside temperatures exacerbate these problems.

Checking your seal is simple: Place a piece of paper or a banknote between the seal and the refrigerator door, then close the door. If you feel resistance when pulling the paper out, the seal is still good.

However, if the paper slides out easily, it's a sign that the seal is worn and needs replacing.

In Vietnam, temperatures have reached 35-37 degrees Celsius in the north. This simple check is highly recommended.
