45+5 uf MFD 370/440 Volt Dual Run Round Capacitor 45/5/440R Condenser Straight Cool/Heat Pump Air Conditioner

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

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.

Air conditioner repair company wanted $595 plus $79 to install new compressor capacitor in our AC compressor. I bought this one with free shipping for $15.99 and installed it myself. No brainer!!! FYI, it's a dual cap; i.e. high Mfd section is the compressor starter and low Mfd section is the fan starter.

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.

Replacement for original part.
