[UL Certified] BlueStars 270-324 uF MFD 110-125 VAC Round Motor Start Capacitor 50/60 Hz AC Electric Replacement Part for AC Motors Starting or Pool Pump or Well Pump

[UL Certified] BlueStars 270-324 uF MFD 110-125 VAC Round Motor Start Capacitor 50/60 Hz AC Electric Replacement Part for AC Motors Starting or Pool Pump or Well Pump

Q: What does "270-324 uF" mean?

"270-324 µF" in a motor run capacitor spec means it has a capacitance range of 270 to 324 microfarads (µF), determining its ability to store electrical energy. This range should match the motor's requirements for optimal operation.

Q: Can I replace a Motor Start Capacitor with a Motor Run Capacitor?

Start capacitors give a large capacitance value necessary for a motor to start for a very short period of time (usually seconds long). A start capacitor can never be used as a run capacitor because it cannot handle current continuously.

Q: I've installed the Capacitor, but my machine is still not functioning properly. What's the issue?

There might be several reasons for this such as: Incorrect installation, faulty motor, capacitor compatibility or other electrical issues. If the issue persists, please don't hesitate to reach out. We're here to help.

Q: Can a motor start capacitor rated 110-125 volts be hooked up to a 220 volt line input? Will it just burn out?

No. The voltage rating of a capacitor indicates the maximum voltage that it can handle safely. If you put a 110-120 capacitor where a 220V is required, it may start the motor a couple of times but will fail very soon.

Q: Can I repair the faulty Capacitor?

Capacitors are typically not designed for repair and are considered disposable components. We recommend you to replace by a new one.

Generic capacitor better than OE

Generic replacement for the original Whirlpool/Kenmore washer. Fit perfectly, same terminals. Made in China vs. original from Mexico. Washer works better than new.

So far so good - working well as a drop-in replacement

Got this to replace an old start cap that came standard on my ancient 1988 Lennox heat pump. I'm not sure if the cap was original to the unit but it hadn't been replaced in at least 20 years and was visibly bulging and leaking, as well as causing a light flicker when the compressor was spinning up. I swapped this out and it is has so far been working well. If I encounter any issues and have to replace it again I'll come back and adjust my rating but a few weeks in I'm giving this 5 stars.

Smaller than original, but worked great 👍

Smaller than the original on my motor, so I had to wrap some foam around it to get it to fit the bracket.
