The invention relates to the field of refrigerator structure adjustment, in particular to a refrigerator and a self-adjusting method thereof. The refrigerator comprises a refrigerator main body and a compressor, the compressor communicates with chambers in the refrigerator body through pipelines, and the compressor is rotatably mounted in the refrigerator main body. The compressor and the refrigerator main body are rotatably connected, if the refrigerator main body is tilted, the compressor can rely on the gravity of the compressor and is not synchronously tilted with the refrigerator main body, the position of the compressor is promoted to be basically unchanged, lubricating oil in the compressor does not have any opportunity to flow into the pipelines, and thus it can be guaranteed that when being started by a user, the refrigerator normally operates.
