If your refrigerator door closes by itself, it is likely due to the operation of a mechanism called a door closer or door spring. These components are designed to help the refrigerator door close automatically once it is slightly ajar. Here's how it works:
Door Closer: Refrigerators typically have a built-in door closer mechanism, which is usually located at the bottom hinge of the door. It consists of a small hydraulic device or a spring that controls the closing action. When you open the refrigerator door, the closer stores energy. As you release the door, the energy is released, causing the door to swing shut gently.
Magnetic Seal: Many refrigerator doors are equipped with magnetic gaskets or seals. These seals create a magnetic force that helps keep the door closed when it is shut properly. When the door is slightly open, the magnetic force pulls it back into the closed position, ensuring a tight seal.
Gravity: Gravity also plays a role in helping the door close. If the refrigerator is level and the door is not obstructed, gravity will pull the door shut once it is slightly ajar.
The combination of these factors - the door closer, magnetic seal, and gravity - work together to automatically close the refrigerator door and maintain a proper seal to keep the cold air inside.
If your refrigerator door is closing too forcefully or not closing properly, there may be an issue with the door closer or the magnetic seal. In such cases, it is advisable to have the refrigerator inspected or repaired by a professional to ensure proper functioning and energy efficiency.
