Testing a capacitor on an AC unit involves determining whether it has failed or is still functional. Capacitors are electrical components that store electrical energy and release it when needed. In an AC unit, capacitors help start and run the compressor, a crucial component responsible for cooling or heating your home.
A faulty capacitor can lead to various issues, such as the AC unit not turning on, humming noises, or premature compressor failure. Therefore, testing the capacitor regularly is essential to ensure optimal performance and prevent costly repairs.
