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 Review: This works good - This works good on our old AC unit ## Features - 25uf / 25MFD 370 Volt or 440 Volt Capacitor.
