There probably won't be a pot, isn't it supposed to have a magentic encoder? It's just a small magnet rotating above an encoder IC.

Here's the A80BHSW that still operates the motor, but doesn't engage the gears and makes a grinding/whining sound like actuator that meshes between the servo motor to the first gear on the bottom has malfunctioned, I can't see any markings on the 3 fets, plus there is a ton of silicone all over the place which doesn't help with visibility either, I don't see any way to compare components on this board to the CT1:
