A/C fan not working

My home ac unit fan stop working last night, did some research and try to diagnose what the issue is, with a stick, I am able to spin the fan freely with no problem, so I open the unit to Check the capacitor, upon opening the unit, I saw a dual run capacitor with only 2 wire connected to it (part# PRCFD5075A from packers), and another module below it which I donít know what it is (part# POC5A from packard), can I assume that whoever install the capacitor was not able to purchase a 50uf / 5 uf capacitor, instead use 2 separate unit for the ac?

Could be.
Test the capacitor with your meter and see if it’s in range.
This is the condenser fan motor correct?

Correct, fan condenser unit, how many volt should I expect from the capacitor?

You’ll have to check it with a meter that reads capacitance.

It's very common to see two capacitors. My personal preference is two caps.

Did you try spinning the motor with the power on ?
You may have a bad motor. Try the new cap in first.

I did try to spin fan, but it wonít turn on, any idea how much will it cost to have the fan/motor replace?

I don’t suggest just buying parts without diagnosing the problem first, but since you already bought the new cap install it and see if the problem remains.

How would I check if the fan / motor is working probably?

Verify correct power to the motor, and test the capacitance of the capacitor.

Just replaced the capacitor, got the fan working, should I be feeling cool air coming out of the vent instantly or it will take some time to feel like?

Feel the larger copper refrigeration line coming out of the condenser. It should be ice cold.

If that is ice cold..... the house should start cooling off quickly.
