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.
