Overheating
Overheating is a common problem in electrical systems where equipment becomes too hot during operation. It's like when a computer or phone gets very warm - but in electrical repair, this applies to all kinds of electrical equipment and can be much more serious. When repair technicians mention overheating in their experience, they're talking about their ability to identify, diagnose, and fix situations where electrical components are running hotter than they should. This is an important skill because overheating can lead to equipment failure, fire hazards, or complete system breakdowns if not addressed properly.
