Goodman CPKE36-1A Capacitor

Hi..
I own a Goodman CPKE36-1A. It recently started giving me issues. The unit would turn on, but the fan will not spin. I have been doing a lot of research and for the most part many recommend to replace the capacitor.

Well, I turned the braker off and opened the unit and found that there are 2 capacitors.. one is bigger than the other.. one says 45 uf MFD the other 7.5 uf MFD... they are single run capacitors.. my question is, how come this unit has 2 of them?

Is one for the HEAT and the other for the FAN?
sorry for the noob question, I know very little about AC units..thanks in advance.

The 45 is for the compressor & the 7.5 would be for the fan.

The larger capacitor (45 MFD) is for the compressor, the smaller one (7.5 MFD) is for the condenser fan (fan on top of outside unit). The 7.5 MFD capacitor is the one you should try replacing.

Thank you guys.. I will try that.. One thing that also confused me is that the manual for this model only shows one capacitor on the diagram.

It probably was originally a dual cap but has been replaced for some reason (new fan motor?).

Well..I turned the AC on and the fan worked without replacing the capacitor.. should I still replace it?

is it normal for it to work one day and not the other if a capacitor is bad?
What I mean is, do capacitors go bad righ away or do they start giving me issues until they completely die?

When it was not spinning.. You could hear it was ON, but the fan would not spin..doesn't that mean that the capacitor is good and the fan motor might be bad?

Most likely the motor. When you replace the motor, also install a new cap.

Spoke with my AC tech over the phone and he said that if the fan has been working since the last time my wife noticed the fan was not spinning.. he said most likely is the AC was in defrost mode and that's why the fan was not spinning... which makes sense.. Thing is that I was not the one that saw the issue, it was my wife..and it was a really cold morning. I guess I will continue to monitor it and see if it does it again

From what you are now saying, you have a heat pump, not just A/C. Big difference. A/C does not have a defrost.
