The answer to 'troubleshooting gets hot' is that a component or circuit getting hot is a common electrical issue that indicates a problem. This could be caused by a short circuit, overloaded circuit, faulty wiring, or malfunctioning equipment. Symptoms include the component or outlet feeling warm or hot to the touch, burning smells, or visible signs of overheating.
The solution depends on the specific cause, but may involve identifying and fixing the short circuit, redistributing the electrical load, repairing or replacing wiring, or replacing the faulty equipment. While some basic troubleshooting can be done safely by DIY homeowners, it's best to call a licensed electrician if the issue persists or you're unsure of the cause, as electrical problems can be dangerous and require professional expertise.
