does the indoor fan blow? If it does you are getting the 24 volts from the thermostat to the ouside contactor need to check your contactor in the oustide unit this is what kicks on the compressor it take the 24 volts and goes to 230 volts to run the compressor and condensor fan. check your schematic for the placement of the contactor.
The compressor/condenser is being called all the time. The reason it goes off is because the evaporator (indoors) freezes up when the fan is told to turn off by the thermostat. This further cooling lowers the low side pressure below the low limit switch point turning off the compressor unit. Solution: Make sure the thermostat is wired correctly. Green wire is usually the compressor wire but maybe not.
