Which statement best describes the function of a motor starter coil energization test during troubleshooting?

In motor starter troubleshooting, the coil energization test focuses on the control side: does the control voltage reach the starter coil and cause it to pull in? This test verifies that the control circuit is complete and that the coil responds to the control signal. If the coil energizes when the control is active, you can be confident the control path is good, and the fault likely lies in the motor circuit or its power delivery rather than the control wiring. If the coil does not energize, the issue is in the control side—open or damaged switch, blown fuse, broken wiring, miswiring, or a failed relay—so you know where to inspect next. Other actions aren’t describing the test’s purpose. Replacing the motor skips checking the control path altogether, which isn’t appropriate when diagnosing why the motor doesn’t start. Ignoring the coil and testing only the motor supply bypasses the control circuit and gives an incomplete picture. Measuring the coil’s temperature focuses on overheating, not whether the coil is being energized or the control voltage is present.
