As seen in the video “How to replace a capacitor -The easiest Way” several steps are involved in capacitor replacement. Remove any screws or rivets holding the old capacitor in place. Also, disconnect all wires from both terminals of the old capacitor.
Apply solder flux to both terminals of the new replacement capacitor.
Next, remove any coating or insulation from the leads with sandpaper or emery cloth. The capacitor will most likely have a polarity, a plus terminal, and a minus terminal. Scrape away any remaining solder with a file or scissor before replacing the component in its original location.
Reattach any wire connectors after placing solder on both terminals of the old capacitor you removed. Remove any insulation from both ends of each wire connector and connect them securely to each end of each lead after applying solder to one end. Take extreme care in correctly aligning the leads with each other, as you do not want to short the two connected leads.
When soldering a capacitor, you must follow the appropriate voltage rating in volts, typical for all capacitors. A capacitor with a voltage rating of 250 volts is a 500-volt capacitor. A capacitor with a voltage rating of 500 volts is a 1,000-volt capacitor. Please insert the new capacitor into its proper place squarely on its mounting strip with both terminals on the same side.
