Howdy:
What turns your compressor on (besides plugging it in :-) is the pressure switch.
When the compressor tank is completely empty, as soon as you plug in the compressor, the "low pressure" switch closes, starting the compressor.
When the pressure in the tank reaches the "high pressure" setting, the pressure switch opens the circuit, cutting off the supply of electricity to the motor, and the compressor stops.
When you start using your compressed air the pressure in the tank starts to fall. When it reaches the factory-set "low pressure" point, the pressure switch circuit will close, allow electricity to flow to the electric motor, and your compressor starts adding more air to your tank.
A pressure switch is just that; a switch that reacts to the air pressure in the system. Yours is not doing so.
If your pressure switch fails to start the compressor motor when the pressure in the system falls below the normal cut in point, then I suggest that your pressure switch needs replacement.
Cheers,
