There could be a couple of reasons your system would do this.
1. Shorted thermostat
Solution - Replace the Thermostat
2. Welded points on compressor contactor
Solution - replace contactor
3. Stuck sequencer
Solution - tap the side of the sequencer with an insulated screw driver. If problem reoccurs, replace sequencer.
4. Jammed cylinder on the body of the reversing valve
Solution - Pull the coil wire on the solenoid and arch it a couple of times to try to free the slide up.

I hope this helps and you get your system back on line
Good Luck and God Bless
