The answer to 'which is better troubleshooting or' is that troubleshooting is generally better than relying solely on electrical repair or replacement. Troubleshooting allows you to identify and address the root cause of an electrical issue, which can save you time and money in the long run. By methodically testing components, checking connections, and isolating problems, you can often fix electrical problems without needing to replace expensive parts or call in a professional technician.
However, troubleshooting does require some electrical knowledge and the right tools. If you're not comfortable working with electricity or don't have the necessary tools, it's usually best to call in a licensed electrician to diagnose and fix the problem safely.
