Motors
Starting, direction, contactors, loading, temperature, and phase-related scenarios.
01→02→03→04→
Motor hums but will not start
Work from mechanical load and supply condition to starting components.
Motor runs backwards
Verify equipment direction, phase sequence, wiring, and safe correction steps.
Contactor pulls in but motor does not run
Check line power, poles, overloads, conductors, and motor condition in sequence.
Motor runs hot
Separate overload, voltage, phase, cooling, cycling, and mechanical causes.
