Capacitor for Air Conditioner 50 uf MFD 370 or 440 Volt VAC, Multi-Purpose Round Capacitor for AC Motor Run or Fan Motor Start or Condenser Straight

During a recent AC compressor overhaul, I purchased this 5µF capacitor as part of a proactive component refresh. I also installed a **dual-run capacitor** rated for both the compressor and fan circuits, anticipating the need for a separate fan capacitor alongside the new condenser fan motor. The 5µF unit arrived quickly, packaged securely with no terminal damage. The aluminum housing was solid, terminals spaced well, and the labeling was clear—ideal for quick identification during install prep. However, the fan motor I ended up installing had a **built-in capacitor**, which meant I didn’t need this standalone part. Instead, I wired the motor directly into the dual-run capacitor using the standard C, FAN, and HERM terminal layout. This worked flawlessly and simplified the system wiring. That’s the key takeaway for buyers: newer fan motors often include internal capacitors, so before sourcing a separate one, check your motor’s spec label or wiring diagram. If your system uses an older motor, this 5µF capacitor appears reliable and well-suited for run/start support. Even though it was returned unused, the build quality and delivery experience made a positive impression. If I were working on a legacy unit again—or troubleshooting a standalone fan circuit—this would be on my shortlist

Very good product, was easy to install and worked perfectly. Installed onto a 5 Ton Rheem unit about 10 yrs old.

Fixed my pool pump not starting issue by replacing the old capacitor with this one

Great product, works as it should great quality, easy to install, definitely recommend.

Purchased to replace a capacitor for my house AC. These are a low cost option to trouble shoot an AC that's having trouble getting the compressor started. This one worked for my hard start kit. Use caution for DIY repairs. It isn't hard but definitely discuss with a professional or watch videos on YouTube to ensure you know what you are doing - including the need to turn off the power and ground the old capacitor before touching the wires.

Perfect fit for a Century/AO Smith 2 hp pool pump J Frame motor where the capacitor is mounted inside the rear cover.

Good quality

Eh, I think this had the potential to do the job, however when I waited 2 days without A/C in Florida on 80 degree days, and it didn’t work I was disappointed to say the least. All I can figure is that it got banged up when shipped. I ended up going to an A/C unit store and getting a different one and sure enough, I finally got my A/C back. Amazon, please start putting “Fragile, handle with care” or something. It was easy to install is something good I can say about it though.

Perfectly working on my Carrier 4-ton Infinity Unit. Installed it yesterday. Hopefully it continues doing the job. Very pleased so far.

Buena calidad tiene aproximadamente 4 meses y a funcionado exelente lo recomiendo al 100%

Perfect capacitor for a portable air conditioner save a lot of cash!

so happy this fixed an old ac.
