    Motor Run Capacitor in AC unit

    The hot summer days from the heat wave around a month ago here in southern california took its toll on my Air Conditioning unit. I tried to turn it on a few days ago as usual..., but the unit would not start up. A quick call to a friend who services AC units got me back up and running again. There was a bad motor run cap that was obviously bulging



    Replacement cap was bought locally for around $15, MUCH cheaper than calling some random AC repairman from the yellow pages. Just though I would share this experience with you guys.

    My brother had the same problem with a large window unit he uses to cool his ranch house.

          Are that AL elektrolytic caps? metall paer should not bulge that way, but may be a litle expensive at that capacity.

            iirc they are paper/oil dielectric.

              Might tell that to the man at the locan junkyard.
              My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.
