I am not familiar with your specific unit as I do not live in the US, but your problem sounds pretty strait

forward. I think you have a contactor stuck in closed position in your outside unit. You will have to verify

that when you run the unit on a high temperature and there is no demand for cooling, the thermostat does

not send power to the coil of the contactor. If the is no power at the coil and the outside unit is running

simply replace contactor. Problem solved.

Check voltage at contactor coils   28 volts should drop out when indoor unit shuts off
