Electronics Assembly (Switch & PCBA)
This unit contains the trigger, forward/reverse sensor, and the brushless motor controller board. In these models, grease from the impact mechanism often migrates into the trigger contacts, or the MOSFETs on the board fail from thermal cycling, preventing the tool from translating a trigger pull into motor rotation.

Forward/Reverse Shuttle
The directional selector physically gates the trigger's travel; if the internal plastic tabs are bent or debris is lodged in the tracks, the trigger cannot reach the actuation point. This creates a mechanical hard-stop that prevents the electronic signal from being sent to the controller.

Brushless Stator Assembly
The stator contains the copper windings that create the electromagnetic field required to spin the rotor. If the tool has been subjected to heavy stalling or moisture, a winding can short or open, resulting in a motor that fails to initiate rotation despite receiving a signal from the controller.
