    Worked out of the box. Beware when installing as the old unit needs to be powered off by touching with a rubber handle screwdriver touching the two contacts at the same time. shut off and remove the fused for you thermo pump. You have been warned!

    5.0 out of 5 stars Saved Me Hundreds – Works Perfectly!
    Reviewed in the United States on May 27, 2025

    When my air conditioner suddenly stopped cooling, I thought I was in for an expensive service call. After some research, I realized the capacitor was likely the culprit, so I decided to replace it myself. This capacitor was a perfect match, easy to install, and got my AC unit running again in no time!
    Within minutes of installation, the unit powered back on, and my house was cool again. The quality feels solid, and it functions just as expected—no issues at all. The fact that I was able to solve the problem myself saved me hundreds of dollars in labor costs.
    If you're experiencing AC issues and suspect the capacitor, this replacement is a lifesaver. It’s reliable, affordable, and gets the job done. Definitely worth keeping one on hand for future maintenance!

    I'm 70, my AC stopped working. Youtube showed me what to check, my capacitor was bad. I called Wolfers heating & AC here in Oregon. They wanted $287.00 for the capacitor, and $99.00 to install it. So, I bought this capacitor, and it was delivered in less than 24 hours. I installed it and works great. All, for less than $15.00. If I can do it, so can you. Great seller, and product. Mike in Oregon

    Capacitor for a PSC motor in a A/C compressor. The product info said overnight delivery at 7am to 10am.
    After my purchase the delivery time said it would be 7pm to 10pm. I was rather upset about this with daytime temps pushing near 100.
    Then, my confirmation E-mail (that I checked latter) said delivery would be between 10am to 2pm. I could work with this.
