Refrigerators can make loud noises, particularly when the doors are closed, due to the difference in pressure inside the fridge. This phenomenon is known as "refrigerator door suction" or "vacuum effect." When you close the refrigerator door, it creates a sealed environment inside. As a result, the air pressure inside decreases, and air is drawn in from the outside, creating a suction effect. This sudden change in pressure can cause a noise, often described as a "whoosh" or a "pop."
During the daytime, you may not notice this noise as much because of ambient noise in the environment. The sounds of daily activities, traffic, or people moving around can mask the refrigerator's noise.
To reduce or eliminate the loud noises caused by the vacuum effect when closing the refrigerator doors, you can try the following solutions:
Slowly Close the Door: Try closing the refrigerator door more slowly. This can help reduce the sudden pressure change and the resulting noise.
Check the Door Seals: Ensure that the rubber gaskets or door seals around the fridge are clean, free of debris, and in good condition. Damaged or dirty seals may worsen the pressure change and cause more noise.
Adjust Door Alignment: If the doors do not close properly, they may create more noise during the sealing process. Check if the fridge is level and adjust the door alignment if needed.
Check the Fridge's Position: Make sure the refrigerator is not positioned too close to a wall or other objects that might interfere with the door closing smoothly.
Replace Worn Parts: If you notice any specific parts of the door mechanism or hinges that appear worn or damaged, consider getting them replaced.
Install a Damper or Cushion: Some refrigerators come with a built-in damper or cushioning system to soften the impact when the door closes. If your fridge has this feature, ensure it is functioning correctly.
Keep the Fridge Clean and Organized: An overcrowded or messy fridge can make the door closing process less efficient, potentially leading to more noise.
Remember that some level of noise is typical for refrigerators, and it may not be entirely eliminated. If you find the noise particularly bothersome and none of the above solutions help, you can consult the refrigerator's user manual or contact the manufacturer's customer support for further assistance or recommendations.
