Need help finding Condenser fan motor
Hi so as of recently my Home AC stopped functioning properly. I found that one of the terminals on the run cap had literally burned off so I ordered one and replaced it.
After installing a new run cap I ran the system and found that after two or three minutes of running the condenser fan would stop even though the system was still trying to run and it made a low humming sound, to boot it was hot to the touch.
So I am looking for a replacement and can't seem to find one that matches so I was hoping someone could help me locate one.
The original model is a GE number: 5kcp29hc a162as
1100 RPM
1/5 HP
208-230v
1.2a
60hz
cap 5.0-370
motor diameter is 5 inches
Fan blade shank 2 1/4 inches
if you need anymore info let me know, thanks ahead of time.

According to an A.O Smith (now Century) cross reference guide, a replacement motor for yours is a Century 9723. Here's a link to that motor on eBay:
Century 9723 5" Dia. Multi-Fit Motor PSC 208-230 Volts 1075 RPM | eBay
Note that it requires a 7.5mfd capacitor, so you'll have to purchase a new capacitor if you want to use this motor.
Here's a link to another page that lists the cross reference capability of this motor.

Alright that shouldn't be a problem. Should I swap out the whole dual capacitor for a 7.5 cap? or could I just run a single 7.5 cap on the side?

You can run a separate 7.5 cap. Just be sure it's wired correctly. If your system uses a dual cap, the other side is used for the compressor, so you wouldn't want to remove the dual cap. The larger value is used for the compressor, while the smaller value is used for the condenser fan.

So if I can find a dual cap that is 35/7.5 mfd(microfarad not millifarad) rated at 440 VAC it should go in without a problem right?

Yes, that's correct. While a higher voltage rating is desirable, since your original motor cap was rated at 370V, 370V is the minimum voltage rating required (anything 370VAC or higher will work).

An improperly wired dual cap will also cause those symptoms.
What color wire(s) are on the Com, Herm and Fan terminals at this time?
What is the make and model number of the outdoor unit?

actually after tracing the wires back through and drawing myself a wiring diagram I realized this cap I got as a replacement has the herm terminal and fan terminal swapped. C is still in the center but when I last attempted to use it the fan wire was on the HERM terminal and the compressor wire on the fan terminal.... probably should of traced the wires in the first place but I was told this part was direct replacement and the old one was so rusted I couldn't see the writing anymore.... Tomorrow during the day I am going to reassemble everything and swap those two wires around and hope that fixes things. Thanks in advance no matter the outcome
