Starting troubleshooting at the power source is essential when addressing a motor failure following a mechanical issue. The power source is the fundamental starting point because, without power, the motor cannot function. This initial investigation ensures that there is proper voltage, indicating that the motor has the necessary electrical supply to operate.

In scenarios where a mechanical failure is observed, it's important to confirm that the issue does not stem from a lack of electrical input. Mechanical problems can sometimes lead to electrical failures, such as if a motor jams and causes fuses to blow or circuit breakers to trip. By checking the power source first, you can rule out any issues related to electricity before examining the other components, such as the control panel, the motor itself, or any connections. These checks ensure a systematic approach to troubleshooting, allowing for a quicker identification of the root cause and preventing unnecessary disassembly of the motor or associated systems.
