A refrigerator often makes loud noises during the day and especially at night: Why is this the case and when should you be concerned if the refrigerator makes a lot of noise? MeinMMO explains what is behind it.
If you go to the refrigerator again in the evening or at night and want to get a drink, you will notice that the refrigerator can make loud noises. But what is behind the noises and when can it become problematic if the device makes such noises?
Every refrigerator makes noise when operating, which is primarily due to the materials used
Where do the noises come from? The loud noises primarily arise from the expansion and contraction of the materials (plastic and metal) when the temperature inside fluctuates significantly. Additionally, the operation of the compressor and the circulation of the refrigerant play a role in typical noises such as buzzing, gurgling, or clicking. Some noises also occur when the defrosting automatic kicks in or ice detaches from surfaces.
How can you limit the loud noises? There are several ways you can narrow down issues with refrigerator noises:
- Stand and orientation: Check if the refrigerator is installed evenly and stable; an uneven stand can amplify vibrations and loud noises.
- Interior and loading: Check if glass plates, shelves, or removable parts are properly installed and that no objects are colliding or blocking the fans.
- Door seal: Test if the door seal closes properly, as a leaking door can lead to increased compressor use and thus more noise.
- Distance to the wall: Ensure that the refrigerator has enough space from the wall and furniture so that vibrations do not amplify or get transmitted.
High and persistent noises can indicate a defect in the refrigerator
When can high volume be a problem? Especially when noises occur very often or frequently, it can be an indication that something is wrong with your device. For example, Ersatzteileshop.de reports this. Here are some things to consider:
- Constant loud buzzing or knocking: This can indicate a defective compressor, temperature sensor, or thermostat. A compressor that runs continuously often indicates a more serious defect – such as damaged insulation, a faulty door seal, or an electronic problem. Here, components can become overloaded, potentially causing electrical issues such as a short circuit.
- Scraping, grinding, or whistling noises: These often arise from a blocked or defective fan or from ice deposits that stress mechanical and electrical components.
- Popping, crackling, or bubbling: If these noises occur more frequently and louder, there may be foreign substances in the cooling system as well as leaks, which can long-term also favor electronic defects
A YouTuber wanted to try out how well a refrigerator can cool hardware. To do this, he modified the refrigerator. But it was hard work and he also had many difficulties. And there are plenty of reasons why you should not recreate this action: YouTuber modifies refrigerator into gaming PC – You should definitely not imitate this
