Have changed out the compressor, pressure switch, drier and it still just cycles off. The compressor keeps turning on and off. Could my air conditioner radiator be bad and need to be replaced?
@jjstehly check it for a refrigerant leak. Also check your pressures. Unlikely that your air conditioner radiator condenser would cause this Update (08/03/2019) The cycling of the compressor could be caused by low charge. There is a high pressure cut off switch and a low pressure cut off switch in a system. As the pressure fluctuates past the range of either one of those the system will be cycling to protect the refrigerant system. Of course, it is possible that the switch on the receiver/drier could be at fault. You need to get the pressure on your system checked for further troubleshooting.
