Trigger Switch Assembly
The trigger switch is a mechanical sliding contact that frequently fails due to ingress of dirt and grass moisture. Wear on the internal conductive tracks or a failure of the safety lock-out return spring prevents the completion of the low-voltage control circuit. Replacing this assembly restores the physical bridge required to send current from the battery to the motor controller.

18V Brushed DC Motor
Standard 18V models utilize a brushed motor where carbon brushes provide electrical contact to the rotating commutator. Once these brushes wear below a critical length, the circuit is broken, and the motor will fail to generate an electromagnetic field. Replacing the motor assembly is the standard resolution as these sub-components are usually pressed or crimped and not individually serviceable.

Battery Connector Block
The terminal interface between the battery and tool is subject to heavy vibration during operation. Over time, the tension in the metal spade connectors can weaken, or arcing can cause oxidation on the contact surfaces. This creates high resistance or a complete open circuit, preventing the tool from drawing power even with a fully charged battery.
