you may have a factory defective unit that is not turning off the anti-frost heating coil (I have assumed yours contains this item based on your problem description). I would trade it in for a new unit, again assuming you have a warranty or the store offers a good in-store return policy. If this plan bombs, then open the unit and find the heating coil near the cool side of the radiator fins. then disconnect the power wires to the heater and prevent electrical short to wires with quality electrical tape.

It is possible that it's the thermostat. When you turn it into cool mode, does the unit come on at all or is it silent? If nothing is coming on, then it's likely it's the tstat. Did the tech check the refrigerant charge while he was there? He should have checked it with the auxillary heat off and the unit just in heat mode. Make sure that the condenser unit outside is coming on when you are calling for cool, If you turn it on and everything comes on, go outside and put your hand on the large copper pipe coming into the unit. In cool mode, this pipe will be cold to the touch and in heat mode, the pipe will be warm to the touch. There isn't much you can do on your own with the exception of changing the tstat. If you can answer some of the questions I have posed, I can try and give you some more answers. Just remember that a check up doesn't mean its a guarantee that something won't happen the next day, it's just that everything was in working order at the time of the checkup.

This is a single speed permanent split capacitor motor for the condenser. One of the capacitor wires shows infinite resistance to hot and netral. The motor needs to be replaced.

It is possible the cover needs removed and the condenser coils are in need of a good cleaning. (the one in the back that is outside).This assuming the compressor is running and it has not developed a leak and lost the coolant charge. Eric

This can happen if the unit is too small for the room. Going by the model number I sounds like a big unit. I would also try cleaning the filters. Also set the temperature higher.
