    Tips: How to identify whether the air conditioning capacitor is good or bad?

    The air conditioning capacitor can be tested for capacity using a multimeter to see if the value is too large or too small. Likewise, it is possible to use a multimeter secondary tube class to test whether the air conditioner capacitor conducts directly. If direct conduction proves that the capacitor is bad. AC and DC circuit capacitor capacity is generally small.

    Questions about inverters
    Hi Sameh, the first two videos shows the inverter without load, and the second with load. In both instances when the inverter is turned on the voltage spikes very high as you can see from the multi-meter. Once you see the video you can better understand. All of this is Between L1 and N with and without load. Bulbs are blowing and between L1 and L2 is 240V as you can see but L1 is unstable. I need to know what to do to stabilize this. It is very important that I do because I have not been able to correct this, and now my job may be on the line if I don’t Need your urgent feedback and results to correct this inverter issue. The issue seem to be coming from the inverter itself.

    ATO Responded
    The 240V voltage (L1, L2) output by the inverter has harmonics, which may cause output voltage fluctuations. In order to solve this problem, we recommend that you buy a CBB65 capacitor with a capacity of 30~100uf and a voltage of 450V. Please connect this CBB65 capacitor in parallel between the output terminals L1-L2, and test again.
    Exactly I needed
    40 5 MFD air conditioner capacitor is fine. I tested it before installing and everything was fine. The AC works again. Just what I needed in this heat.

    This capacitor was a lifesaver for my air conditioner!
    It's exactly the part I need to repair my 10 year old air conditioning system and it's so easy to replace! Eventually I will need a new system but this certainly fits the bill as a temporary solution and the price of this capacitor is hard to beat.

    Good AC capacitor
    Replaced a burnt capacitor in the air conditioner unit. 45 5 mfd air conditioner capacitor works very well. It is better than the AC capacitors recommended by the repair company.

    Capacitor fixes air conditioner easily
    After noticing a bulging starter capacitor and determining that the fan motor was still working properly, it was clear that the capacitor was dead. Thanks to ATO, determining the correct replacement part was simply a matter of placing the order directly with ATO. Parts arrived within 8 days and installation took all of 5 minutes.
