A/C not blowing cool air after repair

Last week the fan motor on my A/C unit went out. I had to order some parts, but I replaced the fan motor and capacitor and got the unit running again. But now it's not blowing cold air where it did just before the fan motor went out. What happened in a week that caused it to stop blowing cold air? What can I do to fix it?

Can you give us a bit more information?

Was the capacitor a dual capacitor?
What color wire did you land on each post if it was a dual cap?

Did you check for any high pressure switches with a reset button?

The make and model of the outdoor unit would also be of assistance.

The system is a Lennox HS9-311-6P

It has two capacitors, a fan motor capacitor and a condensor run capacitor. I replaced the fan motor capacitor when I replaced the fan motor even though it didn't appear blown. The run capacitor seems fine and I did not replace it. It tested out appropriately on a multimeter.

I did press the reset button on the high pressure switch, and the system began running again, but no cold air is coming out like it was before the fan motor seized.
