What does "233-280 uF" mean?

"233-280 µF" in a motor run capacitor spec means it has a capacitance range of 233 to 280 microfarads (µF), determining its ability to store electrical energy. This range should match the motor's requirements for optimal operation.

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.

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.

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.

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.

Perfect Run Capicator for Pool pump

Worked great on my Super Hayward 1 HP pool pump. The original run capacitor is rated 50-400 uf. I read up a little and understood that original run capicator when burns out, makes a humming sound but impeller freely rotates when manually spun around. It may help others to know that you are good to go up a notch on microfarad but not down. I ordered the Upgraded Version 340-408 uf 110-125VAC BlueStar capicator. It was easy to install (I took one wire off at a time from old capacitor to make sure all three are similarly placed). BlueStar capacitor was perfectly sized. It seemed to have a better physical construct quality than the original. Btw I am not a super handy kind of guy but this was easy. Run capacitor is only two outside screws and one inside screw away on an Hayward super pump 1HP (gold). This cost me a little research and 13 bucks, replacement took me 10 minutes max —- saving me hundreds in service/ replacement costs!Few days in, it is going strong. Easy, fast reliable start. Would definitely recommend!!

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.

Craftsman air compressor works again

I used this on a Craftsman 33gal air compressor for the start capacitor. It is not a direct replacement. There is no mount stud at the base. The connections were the same and I just secured it by ty wraps. It functions properly in this installation. My compressor works again.

Fixed my pump

It fixed my sprinkler pump. It's smaller in physical size, but apparently as long as specs are correct, size makes no difference

Easy fix

Saved me $1300! Irrigation company said I needed a whole new pump. It was just the capacitor, and this replacement was perfect!
