Motors Not Working

Some of the V5 motors we have received aren’t being recognized by the brain (The red light on the motor doesn’t turn on and the motor isn’t displayed in the “devices”). We’ve tried switching the cords and the ports, but the motor still doesn’t work. Some of the motors didn’t work out of the box, and some stopped working after being used.

Is there any specific reason why this happens, especially for the motors that are dead right out of the box?

Gonna have to say you got Duds. contact VEX and get some replacement motors sent to you
