1. The ventilation and heat dissipation of the environment are poor. There are three main situations in which the environment around the air compressor affects the heat dissipation: one is that it is too close to the wall, the second is that there are other heat sources near the air compressor, and the third is that the front door and side door of the air compressor are open during operation, and the fan cannot form a strong airflow.
2. The radiator is blocked. When there is a lot of dust in the environment around the air compressor, long-term operation will cause a layer of dust or sludge to adhere to the surface of the radiator, and its internal copper tube is also easily blocked due to the accumulation of oil stains, thus affecting the heat dissipation effect.
3. The cooling oil level is too low.
4. The oil grade is low or the oil quality is poor.
5. The fan tape is broken or loose.
6. The oil filter is blocked or the oil separator is blocked.
7. The temperature sensor fails.
