What might indicate a malfunction in the air compressor governor?

A malfunction in the air compressor governor typically manifests in the way the air pressure is managed and maintained within the system. When the air compressor continually builds pressure without stopping, it suggests that the governor is unable to properly regulate the pressure. The governor's primary function is to monitor the air pressure in the storage tanks and control the compressor's operation by signaling it to stop when adequate pressure is reached and to start when pressure drops.

In this scenario, the excessive and unregulated buildup of pressure indicates that the governor is stuck in a position that keeps allowing the compressor to run continuously. This can lead to increased risk of over-pressurization in the system, which can cause safety hazards or damage to components within the air system.

The other mentioned indications, such as low air pressure in tanks, rapid fluctuations in pressure, or excessive noise while running, point to different potential issues within the air system rather than specifically identifying a governor malfunction.
