[2025 Updated] BlueStars 540-648 uf/MFD 110-125 VAC Volt Run Round Start Capacitor ±20% CD60 Replacement Part - Fit OEM Single Phase Motor Capacitors Condenser Straight Cool Heat Pump Air Conditioner

Came the next day, easy install on pool pump motor. Was a direct fit replacement, and the motor started just fine after install. Will buy again if necessary.

Good quality and good product.

Purchased it because my air compressor kept tripping a breaker when it tried to start. Thinking it was the start capacitor, I purchased and installed this one (along with a new run capacitor because I thought they were both old so I might as well replace them both.) I turned on the compressor and...tripped the breaker. I tightened all the wire connections thinking that might be the problem and...tripped the breaker. Out of frustration and the need to have the compressor working, I took it to an electric motor repair shop. They tested the new capacitor (it was perfect) and installed it. Ran perfect. After paying $142 to the shop (grrr) I took it home and plugged it in. Tripped the breaker. Took it to another outlet on a different circuit and plugged it in. It started and ran perfectly. That's when it dawned on me that the problem was likely a faulty breaker. Switched out the breaker and flipped on the compressor. You guessed it, it ran fine. The moral of my $142 story is don't be dumb like me. Test your "bad" capacitor if you have that capability (I didn't). On the bright side, I have new start and run capacitors. :-)

This start capacitor does the job well and has been reliable for my AC unit. It’s easy to install and fits perfectly. The only reason for not giving 5 stars is that the packaging could be improved to ensure it arrives without any damage. Overall, a solid replacement part that works as expected.

The capacitor work fine. Motor started right up.

Delivered quickly, correct item. Good price.

Replaced cap in Robinair 15600 Vacuum pump. This one is rated for 220VAC way above the original 120VAC - which is a good thing. It, also, was a little bit bigger than the original, but still fit in the cavity in the pump handle nicely. Hopefully, it will fix the startup stalls my pump was beginning to have.

Good and fast
