Perfect replacement, got my AC running instantly!
Great capacitor! My central AC fan had stopped working, but dropping this 50+5 MFD BlueStars unit in fixed the problem immediately. It is UL Certified, fits the standard round mounting bracket perfectly, and works for 370V/440V setups. If your AC compressor or fan motor is struggling to start, this is a quick, high-quality, and affordable fix.
