[UL Listed] BlueStars 3 uF MFD 370-440VAC CBB65 Oval Run Capacitor 50/60 Hz | for Central Air-Conditioners Heat Pumps Condenser Fan Motors AC Compressors

Capacitor is as described. Works great in my AC unit. For $20 vesus $150 or more that the HVAC company was going to charge. Just pull the power on the wall, remove the cover and then one screw and 3 wires is all it takes. Even people less handy can do this and save a bunch of money.

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.

When the HVAC gentleman came to the house, I asked him what the cost was to replace e the capacitor, he replied $254.00. I had replaced one before at our old house. I paid $14.00 for our new one and it works great. I was very happy to save over $200. WARNING YOU CAN GET SHOCKED REPLACING A CAPACITOR WITH HIGH VOLTAGE SO READ ABOUT IT FIRST. It fit perfectly the connections were the same and it’s working well.

This product was exactly as described. Part was installed immediately and functioned properly. At the time of this review, part has only been in use for 1 week. Time will tell the quality of the unit.

Based upon HVAC posts that I have seen on the internet by HVAC service technicians and information from my brother, the most common failure on whole house AC System Compressors is a bad Start Capacitor. This was the case with my 5-year-old system in Florida. Not only did the BlueStars capacitor easily resolve my AC problem, but it was delivered early the next morning after I ordered it. This allowed me to repair my AC system before a high temperature and humidity problem could start in the in the 90-degree weather we were having in SW Florida. Great product, reasonably priced and great service from the vendor.

Item was as described and worked with my blower motor. So far no issues

Works in our Coleman Mach AC Unit.

Used this to replace an old capacitor in my AC condenser. Fit perfectly, capacitance was spot on as measured with a Fluke 189 DMM. Good deal if you need a replacement. Hopefully it lasts a while.

Fonctionne très bien pour le prix

Il est arrivé tous bosser

Capacitor work great and arrive before promised date.

Refacción de buenas prestaciones. Mi equipo volvió a funcionar y ahora es cosa de esperar para checar la anunciada durabilidad.

Swapped out with original part no issues
