Help with replacing Dual/Single Run A/C Capacitor(s) (AC, outside)

[OmegaSupreme]

I have two capacitors in my outside AC unit, my fan has stopped working and makes a buzzing sound. I did the screw driver trick and it seemed to work for a little while

here is one of the capacitors, fan terminal is not connected, blue wire goes into HERM, it is an Aeromet ii m26p4440w05:


and the other:


I tried to replace the Aeromet with a Motor Dual Run Capacitor Round 40 + 5 uf MFD 440 Volt, as seen below


but then decided not to turn anything on, since it's too risky as I'm not even sure this is the correct replacement since it's DUAL RUN...

Can anyone help?

If the original cap is rated at 40/5 370, why don't you use that? The 7.5 mf cap will likely ruin the fan motor.

The original fan cap is 7.5 it looks like, why did you replace with a 5? You should have bought a 40/7.5 cap.

Did you test the original cap? What was it showing for uf when you pulled it out?

IIRC the fan motor should connect to the common and fan portion of the dual run cap.
