What is a common cause of an air compressor running continuously?

• A. A clogged air filter
• B. A pressure switch malfunction or an air leak
• C. An inadequate power supply
• D. Low ambient temperature

Answer: (B)

An air compressor running continuously is often attributed to a malfunction in the pressure switch or the presence of an air leak. The pressure switch is a critical component that controls the operation of the compressor by monitoring the tank pressure and turning the compressor on or off as needed. If the pressure switch is faulty, it may not signal the compressor to stop running once the desired pressure is reached, causing the compressor to operate continuously. Similarly, an air leak in the system creates a situation where the compressor cannot maintain the required pressure in the tank. As air escapes through the leak, the pressure drops, prompting the compressor to work harder and, ultimately, to run continuously in an effort to replenish the lost air. This creates unnecessary wear and potential damage to the compressor, making timely diagnosis and repair essential to ensure efficient operation. Factors like clogged air filters, inadequate power supply, and low ambient temperature can affect compressor performance but are less likely to result in continuous operation. A clogged air filter typically restricts airflow and may cause the compressor to cycle off due to high pressure, while inadequate power might cause the compressor to stall or improperly function. Low ambient temperatures can affect efficiency but do not inherently lead to continuous operation.
