at the condenser unit mounted outside of the control box you'll find a lo and hi limit cutout. these operate off pressure. too high they trip too low thet trip. there may be a reset button on each of them. your control circuit is probably 24 volt so check for a small cartridge fuse that has blown. chek to reset the motor contactor for the condenser fan. check for a reset for the air handler motor.

I would think that at just 3 months this unit shoud still be under warranty. Central A/C is a fairly complicated system, and I don't recommend "poking around" at it.

You have obvious things like the main breaker, but again, why did it quit at 3 months.....just get the warranty service.
