Replacing your air conditioning capacitor could come at a high cost, but contact a professional HVAC company to test your AC unit before proceeding with repairs or replacement. If you can't isolate the smell to a particular component, sniff the power supply. One ceiling fan capacitor is there to help jump-start the fans phase shift, while the other capacitor is expected to encourage a phase shift in the fans windings. Did it kill my hard drive? On average, AC capacitors last up to 20 years with regular maintenance. If screws are holding the capacitor in, make sure you keep them somewhere safe. Blown capacitors are the number one reason for hard starts in an air conditioner. That's good enough for me. When the problem persists, it's time to consider calling the HVAC experts to perform air conditioning repair service and replace the AC's capacitor. Not everyone likes the smell of indole - especially in large amounts. Like a battery, a capacitor stores energy. If they fail, however, they can cause serious damage to the system. The top of a blown capacitor will be slightly bent outwards in a convex shape, rather than flat or slightly indented inwards like a working capacitor.
