Really good quality capacitor
Used this capacity in my RV AC and now the motor kicks in quick. It function is better than I expected for the value of money. And easy to install, has good thick electrical lugs. Be sure that the old capacitor is properly discharged before removal. Do not cross the leads or lugs to discharge as the spark can damage tool or lugs.

Big Savings, Small Effort – A Must-Have for DIY HVAC Repairs
This capacitor was a lifesaver—both for my air conditioning unit and my wallet. When my condenser stopped working, I diagnosed it down to the capacitor. Instead of spending $300+ on a service call for something that takes five minutes to fix, I ordered this replacement, popped the cover, unplugged the old one, and connected three wires. The Canamax capacitor feels solid and well-built, and it got my AC system running again instantly. It’s compatible with both straight cool and heat pump systems, and it came well-packaged with clear labeling for the terminals. For homeowners comfortable with basic DIY electrical repairs, this is a smart purchase that can turn a stressful HVAC failure into a simple afternoon fix. It’s a perfect example of a quality product that empowers people to take control of their home maintenance—highly recommended.

Works fine, but a couple of points to watch out for.
This product is what it claims and does what it claims. Two things to watch out for, though. Because this is rated for 440 VAC service, it is physically larger than one rated for 370 VAC. My original was the latter type, so this one did not fit in the same clamp in my air conditioning unit, and I had to come up with my own mount. I should have anticipated the size difference based on voltage, but simple solution would be for the makers to publish the diameters and heights of their units. I expect they are all industry standard for their voltage, but home installers won't automatically know that, so size information would be useful. A second item I'll mention is my unit came with some dents in the sides. This is because it is shipped in an unpadded envelope inside a thin cardboard box that is not adequate protection for shipping. This is the main cause of me not giving the full five stars.

tested microFarads while still in the box = 7.5/44.6 which is within acceptable range, all good to save as my spare capacitor.

The capacitor arrived on time but was dented and evidently I was disapointed. It works ok.
