I'm trying to find a replacement dual run capacitor for my window unit air conditioner. Here's all the particulars: it's a CBB65A-1 type, it's round,about 3&5/8" tall and 2" in diameter. It's 270 vac the mf is 50+6uf +or- 5%, 50/60HZ It's a dual run so it has three terminals on top. It also has other numbers,but don't know what they mean: 25/80/21 it also has 5.1/0.6A right after 270 vac on the label. I've scoured the net and can find nothing on them,I've found some that are close but no cigar,like the voltage is wrong or the micro farads are wrong. I did find a place where I think the cap originated called Alibaba I think they're in China maybe? but even they didn't have an exact match. If there is one out there that is not necissarily the same,but comparable I sure don't know where to look. Any help would be greatly appreciated. Thank you for your time. -pat- [email protected]

Hello
Before you buy a new condensor fan motor check the contacts to the motor are not worn or pitted.
Hold or push the contactor in by using an insulated screwdriver and see if the fan motor turns.
Also the start cap you bought? was it the correct one meaning mfd micrfarad?
If all the above checks out ok then you need a fan motor,you can wire the motor direct to check it also.
From what you describe it sounds like the fan motor is burnt up and worn out,not uncommon.

That is a dual capacitor - 2 capacitors in a single casing. Replace it with 2 separate capacitors , which you can buy here

Just make sure to match the voltage rating and the polarity correctly.
The cables can be replace with every ones you can get your hands on - just make sure the thickness of the actual metal cable is as large as the cable you are replacing.
if there is only two terminals then it does not matter which wire goes where
I just had the same problem. I replaced the motor with no luck. It turned out to be a bad capacitor. If it is a dual capacitor, three prongs on top, it also starts the compressor. It is recommended to replace the capacitor anytime you replace a motor. I would try replacing the capacitor first. It is a lot cheaper that a new motor. If that does not fix the problem then you can get a motor. No harm, no foul. The slow start of the motor is a common symptom of a bad capacitor. The motor is not getting enough voltage. The capacitor increases the voltage like a transformer. It will boost it to almost 400 volts, depending on your unit.
