Servo question.

Servo question.
What would cause a servo's motor to continuously spin while the servo is not receiving any inputs? I have a Futaba s9351 throttle servo, and at neutral, all radio(DX3R) settings neutral, the servo is spinning. The gears aren't turning, although they will if I pull the trigger on the radio, but there is a constant sound of a motor running, and within a couple of minutes, the servo was over 100ºF. The steering servo is fine, no noises, no complaints. I was thinking stripped gears, but the servo functions properly with the pull of a trigger, but it does make a continuous sound and get hotter than I'd like a neutral servo to get.
Thanks.
Thanks.

means its time for a new servo

Digital servo's make noise with a load on them...Even the slightest bit from a throttle spring....if that's what your hearing...your description makes me think other wise...but still its a shot in the dark.

I actually figured it out; it involved taking the servo apart. The main gear was somehow not at neutral, like it had skipped a tooth over. I guess the servo was trying to center and the motor was constantly spinning. I had to take all the gears out and try and set them back up where they wanted to be. The internals looked fine and it is operating as well as or better than it used to.
