Motor performance issue

One of the motors on my schools VEX IQ stopped driving a wheel. The motor could still be heard running though. Upon removal, the motor turned normally. But the moment it was put under any stress by connecting it to anything it would stop turning although as before, it could still be heard making noises from inside the motor. Is it defective?

Hi Macphot,

We’re sorry that you have encountered this issue. If you can hear the internal motor spinning, but the output shaft is not, this would mean that at least one of the internal gears in the motor is damaged. If this was a recent purchase, please contact VEX Technical Support at support@vex.com or by calling +1-903-453-0802 for more assistance with this issue.
