You hear the compressor kick in (Hum) but no fan comes on? Will the fan come on when just in fan mode, not cool, or do you have that set-up?

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.

I think the wiring diagram is on a printed sticker on the side of the water collector, just pull it out of the right side as you look at it. There should be one on there hope this helps as i have the same unit in the other room. regards Richard

The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.
