Compatibility & Fitment

  • Designed for continuous duty in motor run applications.
  • Used in air conditioner condensers, heat pumps, furnace blowers, and other single-phase AC motors.
  • Compatible with systems specifying either a 370VAC or 440VAC capacitor. A 440VAC capacitor can safely replace a 370VAC unit.

When to Replace

  • The motor hums but will not start or struggles to start.
  • The fan or compressor fails to turn on.
  • Visible signs of damage, such as a swollen or bulging top, cracks, or leaking oil.
  • Capacitance measures outside the specified tolerance range when tested with a multimeter.

Installation Tips

  • Disconnect all electrical power to the equipment before servicing.
  • Safely discharge the existing capacitor by shorting the terminals with a properly insulated tool.
  • Confirm that the capacitance (MFD/µF) and voltage ratings are appropriate for your application.
  • Ensure terminals are connected securely. Polarity is not a factor for this type of AC capacitor.

Genuine parts that keep my S1 Pro running like new
Fit & Quality: Everything fit perfectly on my Eufy Omni S1 Pro — the rollers snapped right in, and the filters matched the originals exactly. You can tell these are genuine Eufy parts, not knockoffs. Performance: After swapping the brushes and mop roller, my vacuum immediately started cleaning better again. Suction improved, and it picked up fine dust I hadn’t noticed before. Ease of Use: Installation took less than ten minutes. Everything comes sealed and labeled clearly, which makes it simple to replace parts without guessing. Value: It’s a little pricey compared to third-party kits, but the quality and compatibility are worth the extra few bucks. Verdict: Solid replacement set that restores performance to like-new.
