What happens when a air compressor keeps running?

If your compressor runs continuously but doesn't seem to build enough pressure to cut off, you could be experiencing a leaky gasket. Sometimes the compressor will build pressure up to a certain point (say 50 or 60 psi, for example) and then it will just keep running without building any more pressure.
