Technician A is correct. When working around electric cooling fan motors, it is necessary to disconnect the power source to avoid any electric shock or injury. Even when the ignition switch is off, there may be residual power in the system, which can still pose a risk. Therefore, it is always better to disconnect the power source before working on electric cooling fan motors.
