Noise and humming of the refrigerator
Refrigerators are an integral part of our household appliances, but sometimes they can become a source of unwanted and even extremely loud noise. The noise of the refrigerator can be quite annoying, especially if it is located near the bedroom or living room. Such noise can create a feeling of discomfort and disturb rest.
The causes of the noise or humming of the refrigerator can be diverse. Here are some of them:
- Imbalanced compressor: The compressor is one of the key parts of the refrigerator that is responsible for its operation. If the compressor is not balanced, it can cause noise and humming.
- Improper refrigerator placement: If the refrigerator is not installed evenly or is not placed on a flat surface, it can also cause additional noise.
- Clogging of ventilation holes: If the ventilation holes of the refrigerator are clogged with dust or dirt, it can lead to improper air circulation and, as a result, noise.
- Deformed speaker: The internal speaker in the refrigerator can be deformed or damaged due to vibrations and cause noise.
- Malfunctioning fan: The fan, which is responsible for air circulation in the refrigerator, can cause noise if it is not working efficiently or if it is worn out.
- Loud clicking sounds: Temperature expansions of plastic parts can cause loud clicks of the casing.
Now let's consider several ways to eliminate the noise of the refrigerator:
- Check the level of the refrigerator: Make sure that the refrigerator is installed on an even and flat surface. Use a level to check for horizontalness. If it is not level, try using adjustable legs or pads under the refrigerator.
- Clean the ventilation holes: Regularly maintain the refrigerator by cleaning its ventilation holes from dust, dirt, and other contaminants. This will ensure proper air circulation and reduce noise.
- Check the compressor: If the compressor is unbalanced, contact a refrigerator repair specialist to balance or replace it.
- Replace the speaker: If the internal speaker is damaged or deformed, contact a professional to replace it.
- Service the fan: Disconnect the refrigerator from electricity and check that the fan is not damaged or clogged with dust. If necessary, replace or clean it.
- Eliminate loud clicking sounds of the casing: Temperature expansions of plastic parts and subsequent sounds in the form of clicks are rather design flaws of the refrigerator. There are no ready-made recommendations for solving this problem.
If the noise and humming of the refrigerator still continue, do not hesitate to contact a refrigerator repair professional. They will be able to conduct additional diagnostics and help you solve the problem.
