Frequently Asked Questions

Common signs of a failing pool pump capacitor include:

  • The motor hums but doesn’t start.
  • The motor starts slowly or intermittently shuts off.
  • You hear a clicking or buzzing sound near the pump.
  • The capacitor appears bulged, cracked, or leaking oil.

If your motor exhibits any of these symptoms, replacing the capacitor is usually a fast and cost-effective fix.

Always match the microfarad (µF) rating and voltage printed on your old capacitor label.

For example, if your current capacitor says “30 µF 370V”, the replacement must have the same µF rating and equal or higher voltage (e.g., 370V or 440V).

You can also reference your motor’s model number (found on the motor label) to find the correct capacitor in the manufacturer’s specifications.

On average, pool motor capacitors last between 3–5 years under normal conditions.

Heat, humidity, and frequent cycling can shorten their lifespan. To maximize longevity:

  • Keep the motor well-ventilated.
  • Protect it from direct sunlight and water exposure.
  • Inspect the capacitor every season for signs of swelling or corrosion.

Yes - many homeowners can safely replace a capacitor in just a few minutes.

  1. Turn off power at the circuit breaker.
  2. Discharge the capacitor using a resistor or insulated screwdriver.
  3. Note the wire positions or take a photo before removing it.
  4. Install the new capacitor, securing wires to the same terminals.

If you’re not comfortable working with electrical components, hire a licensed technician.

  • Start capacitors provide an initial energy boost to get the motor turning.
  • Run capacitors help maintain a steady current and motor efficiency after startup.
    Some pumps use both, while others use only a dual capacitor that performs both functions.

 The most common reasons include:

  • Overheating due to direct sunlight or high ambient temperatures.
  • Moisture exposure, leading to corrosion.
  • Frequent cycling or short run times.
  • Voltage fluctuations or electrical surges.

If you have a multimeter with a capacitance setting, disconnect the capacitor and measure across the terminals.

The reading should be within ±6% of the rated µF value.

If the reading is far off, or if the capacitor shows physical damage, it needs to be replaced.
