What is an important step to take when troubleshooting a single-phase motor?

When troubleshooting a single-phase motor, starting with the power supply issues is essential because the motor's operation hinges on receiving adequate electrical power. If there are problems with voltage supply, such as insufficient voltage, phase loss, or tripped breakers, the motor may not start or operate correctly. Ensuring that the power supply is reliable and within specifications is the first step, as even the best motor components will fail to function without the proper electrical input.

By prioritizing the inspection of power supply issues, you significantly streamline the troubleshooting process. Once you confirm that the power supply is stable and within acceptable limits, you can then proceed to evaluate other components, like the electrical connections, bearings, or motor housing. Addressing power supply problems first eliminates one of the most common issues, making it easier to identify more complex issues if the motor still does not operate as expected.
