Answer
Hi Johnny

You need to check the service valve and make sure freon is going thru.
If it does not go thru change valve.  If it is going in then check power at the compressor and at the cycling switch.  Compressor will turn on only if you have freon (50 psi min.) in system so the cycling switch will close and let the power go to the relay and compressor.
