Why the heck is my compressor turning on and off, and on and off, and on and off?!
Has the compressor unit been modified?
The compressor motor should be the kind of power it is rated for. If it is a 120 volt compressor motor, the power feed needs to be of 120 volts.
If it is a 240 volt compressor motor, the power feed needs to be 240 volts.
If the compressor says it is 120/240 volts, then that needs to be checked, the wiring diagram given for the voltage applied must be followed.
Wrong voltage to the motor will cause an overcurrent or overload on the motor and cause the motor protection device to short cycle the operation of the motor.
If the above is correct in the compressor wiring, check the pressure switch.
The pressure switch energizes and cuts power to the motor directly. Is the pressure switch contacts staying closed? Is the pressure switch reading the tank pressure? The pressure switch has springs keeping pressure for them to stay closed, in contact, and if the contacts are pitted or defective, intemitent contact may show as a result.
Personaly, I think you have the compressor connected to the wrong voltage.
