  • General purpose AC electric motors

When to Replace

  • Motor hums but does not start or struggles to start.
  • Fan blades or blower wheel require a manual push to start.
  • Visible signs of damage such as a bulging top, leaking fluid, or corrosion.
  • Capacitance measurement is outside the rated tolerance (±5%).

Installation Tips

  • Disconnect all electrical power to the unit before servicing.
  • Safely discharge the old capacitor by shorting the terminals with an insulated screwdriver.
  • Ensure the µF rating of the new capacitor matches the original part exactly.
  • The voltage rating of the new capacitor must be equal to or greater than the original.
  • Note or photograph the original wire connections before disconnecting.

FAQs

Common symptoms include the AC unit or motor failing to start, a humming sound coming from the motor without it turning, or the fan requiring a manual push to get moving. If the top of the capacitor is bulging or domed, it has failed and must be replaced immediately.
Yes. A 440 VAC capacitor is rated for a higher voltage than a 370 VAC unit, making it a safe and compatible upgrade. It will function perfectly in a 370 VAC application, provided the microfarad (uF/MFD) rating matches your original part.
Yes. The microfarad rating must match your original capacitor within the ±5% tolerance. Using a capacitor with the wrong uF rating can cause the motor to overheat, run inefficiently, or fail to start entirely.
Always turn off the power to the unit at the disconnect or breaker box before beginning. Capacitors store an electrical charge even when the power is off; use an insulated screwdriver to short across the terminals to discharge any remaining energy before handling the unit.
Installation is generally straightforward and takes about 15 to 30 minutes. You will typically need a screwdriver or nut driver to remove the service panel and a pair of needle-nose pliers to disconnect and reconnect the spade terminals.
Run capacitors are heat-sensitive components. Over time, internal dielectric breakdown occurs due to high ambient temperatures, frequent power surges, or age. Keeping your condenser coils clean and ensuring proper airflow around the unit can help extend the life of your new capacitor.
