45/5 uF 45+5 MFD 370V/440V Dual Run Start Round AC CBB65B Capacitor 45 5 uF 370/440 Volt VAC Air Conditioner Capacitor for AC Unit Fan Motor Start, Heat Pump, Condenser Straight Cool

Have a 10 yr old carrier ac only unit, died after a short power outage. Troubleshooting pointed to a capacitor problem (compressor started, but fan couldnt get going, but manually pushing it with a screwdriver got it spinning). This capacitor was an exact fit to my old one's size (a Castor oil model) so no need to mess with the bracket. So far its working well! And 1 day delivery was great, didnt have to wait in August Virginia heat.

I installed this capacitor in our a/c two days ago, and it is working fine so far. It is a direct replacement in all ratings and terminal locations. I had already replaced the original capacitor with separate 45uf and 5uf capacitors a few years ago, so I can't speak to the exact size and mounting clamp being the same or different as the original. This unit was easy to mount and is secure using the mounting clamp I made. One common reason for failure of this type of capacitor is power line fluctuations. That can occur if the power shuts off unexpectedly (e.g. storm), from lightning nearby, power spikes, and other types of power problems that cause voltage instability. Over time, the capacitor's performance will degrade until it fails. This is true of all polymer capacitors, not just the one from this supplier. I keep a spare capacitor because of the occasional power fluctuations we have in our area. I will be ordering a second capacitor from this supplier so I still have a spare.

Works as it should. I did a preemptive replacement on my outside A/C fan last Fall. It's been working fine, specially considering how hot the Summer has been this year (2024). Yah I would buy again.

Prompt delivery and in excellent shape.

Exelent product

The fit was perfect and it cooled as if was the original. Mybhusband had no problems replacing it and it had a smooth install.

Save yourself a few hundred dollars! Do it yourself with just $20. Simple to do and fit perfectly!

Its a capacitor, either it works or doesn't. My old one was still working but if replacing a fan motor is silly not to change this out as it was rusty and who wants to go back in the panel again? Diameter isn't listed and this one is larger but not as large as the OEM in my Trane. Just had to bend an re-drill the strap. Well marked on all posts.
