    Solid product and a good value
  

*by D***. on Reviewed in the United States on April 13, 2024*

Capacitors are wear items that are best either proactively replaced before they go bad or, at the very least, you should keep a properly rated spare on hand for when the one in your current AC unit inevitably quits.  Furthermore, replacing a capacitor is a job that is well within the average DIY’er with nothing but the most basic tools required.  There are plenty of YouTube videos on how to do it and do so safely.  That is, unless you want to pay an HVAC repair company $200/$300/$400 or more when your capacitor quits (and it will eventually) on the hottest day of the year.  Yes, that is what they charge to replace a capacitor.This Blue Stars brand dual run capacitor arrived promptly and when tested with my Klein MM700 multimeter was almost spot on the label rating and well within the claimed 5% tolerance.  Replaced an aging Dayton (Grainger) part number 2MEK3B of the same specifications (50 + 7.5 mfd) in a 20 year old Lennox central air unit (not the original capacitor).  The dimensions of the Blue Stars capacitor (both diameter and height) matched the Dayton unit being replaced exactly and were consistent with the product listing.  The capacitor being replaced was still working and tested OK so it will go on the shelf as a spare.The capacitor itself is clearly marked (C=common, FAN, and HERM (compressor)).  Terminals feel solid as does the metal (aluminum) casing.  Did not weigh it but felt as heavy (if not slightly more) than the capacitor it was replacing.  The product labeling clearly shows China as the place of manufacture but claims it is UL (USA) and CE (Europe) certified (but I have no way to verify this).  Product listing in Amazon states a 100% lifetime warranty.  Can’t vouch for that either.When installed and tested, the AC unit fired right up with the new capacitor.Far less expensive than I could find locally (Southwest Ohio).  Certainly inexpensive enough to either purchase to have a spare on hand or, like me, proactively swap out an aging part before a problem occurs so I could do it at my convenience and schedule.As noted above, replacing a capacitor is not rocket science and within the ability of anyone that can replace a household light switch.  Just make sure you get a capacitor of the right microfarad (MFD) rating for your application and TURN OFF THE POWER before you even think about starting the project.  This means either flipping the circuit breaker in the main panel for the AC unit off or using the exterior safety disconnect switch where the AC interconnects to the house power.  Simply turning off the switch on the furnace or thermostat IS NOT ENOUGH.  Also, a capacitor, even one that has failed, can hold a residual charge and, therefore, make sure you discharge the old unit.  Again, there are many videos available on how to do this and do it safely.  Do some homework if this is new to you as saving a few dollars is not worth a serious injury or electrocution.Can’t comment yet on durability or service life but will update if it fails prematurely.  Otherwise, a good solid product and an excellent value.  Five (blue) Stars.DISCLAIMER:  I am a member of the Amazon Vine program.  This means that I receive some products free of charge to use and review.  I only request/accept items I will actually use.  My reviews are based on this real-world usage – they are not mere regurgitations of the Amazon product description or insincere hype.  I am not a shill and I do not consider the fact that an item was provided without charge as part of my ratings.  I have given Vine products one star, five stars, and all points in between.  I put serious effort into my reviews and they represent my honest opinion of the product.  My hope it they will help someone make an informed, educated choice whether or not a product is right for them.

    Perfect replacement
  

*by E***S on Reviewed in the United States on July 20, 2024*

Used on my Lennox A/C to replace the same capacitor specs; working perfectly. I replaced a six year old capacitor for preventive maintenance reasons; works great and much cheaper than having an HVAC tech do the simple work.
