PowerWell 40 + 5 MFD uf 370 VAC or 440 Volt Dual Run Round Capacitor PW-40/5/R for Condenser Straight Cool or Heat Pump Air Conditioner 40/5 Micro Farad

It simply works on my AC unit.

I got two of the PowerWell 40/5 MFD +/-6% capacitors. I received them on time and right away I measured them, the values were 40 and 5 MFD on both capacitors, which is fantastic since the values can vary +/-6% and they are still acceptable. The fact that they both were at 40 and 5 MFD was very impressive and it shows these capacitors are of high quality and the manufacturer pays attention to details and quality of their products.6 years ago, I bought two American made 40 MFD +/-5% motor run capacitors for over twice the price of these Powerwell caps. The nominal values of both caps were at 40.7 and 40.6 MFD which were well within the specified tolerance but I expected for such a high priced caps better quality control. The value should have been at 40 right out of the box. Of course, I installed them and they have been working for the past 6 years without any failure. They were guaranteed for 5 years. I replaced them since I do NOT want any failure in the middle of summer in Phoenix.As far as Powerwell caps, they have been working in my outside units for only a month. They have not gone through any summers yet. The summers (118 F) are brutal on motor run capacitors. Also, heat and time can change the value of the capacitor. So, my Powerwell caps have NOT gone through the time and the heat test yet. I hope they perform well during Phx's summers. I think they will, based on what I see so far. My outside units (heat pump) run very smoothly so far. I will update this review after a summer or two to let you know how these caps performed during harsh summers of Phx, AZ. At this point, I would definitely recommend them because they are priced very attractively and they have 5 years guarantee. In addition, they appear to be high quality. Also, best of all, they are filled with Caster oil and not PCB.

Texas heat starts early, first warm days the AC unit in our apartment stopped cooling and landord dragging feet. Inside unit clean and running, outside had the fan running. Tested the cap and found condenser side bad. This part shipped quick and was easy to install. Dogs and kiddos back to comfort. May grab a couple to keep for spares.

Good price, easy to install and working well.

Looks exactly the same….measures correctly, work fine so far.
