If you hear this, replace the capacitor promptly, as the engine itself could burn up if the capacitor fails to begin the motor. When the holes are clean, you can proceed with installing a new capacitor. When it comes to air conditioning, there are two main types of capacitors, run capacitors and start capacitors. After removing the bad capacitor, you must clean the holes before you can put a new one in place. It saves space by combining two capacitors in one. There is a maximum of +10% tolerance in microfarad rating on replacement start capacitors, but exact run capacitors must be replaced. Again, this is a dual run capacitor. It might even be faster to get the job done on your own, especially if it’s summertime and you want to escape from the heat of the streets to the freshness of your home. Obvious signs of failure include a gooey, leaky or bulging capacitor or a burned contactor. On the replacement capacitor the voltage rating must be equal to or greater than the original. FREE Shipping on orders over $25 shipped by Amazon. A faulty capacitor does not do this properly. If you’re working with a branded unit and want to use their parts, the cost can shoot closer to $400 so be sure to ask. AC repair costs $125 to $459 on average for small jobs, such as a tune-up, freon recharge, fan motor repair, or capacitor replacement.
