It sounds like your condenser fan motor may be locked up or the capacitor that helps give the condenser fan motor a kick to get it started may be defective. Try turning your system on and using a long screwdriver try to push the fan blade on the condenser fan motor to see if it will run normally if you give it the starting boost it needs.If it does run at full speed and doesn't over heat or start and then slow down then you probably only need to replace a simple 10-12$ capacitor. If it barely turns, makes an odd humming sound or overheats etc. then you will have to replace the condenser fan motor. This is assuming that the outdoor condenser has the 220v supplied and the 24v supplied to the compressor relay, that the compressor relay is engaged and suppling 220v to the condenser fan motor.

Mine has a model number of PCA061D.
If you remove the water capture reservoir, there is a sticker that has the model number.
