Two model HXT900 servos were tested. Both failed at approximately 40,000 cycles.
The component that failed was the potentiometer, which developed dead spots.
The Servo could continue to be used if the operating region was changed to a different position on the potentiometer.
The image below shows the potentiometer removed from one of the failed servos, showing the worn area. This potentiometer has two wipers.
