Motor Controller Assembly
The brushless DC motor relies on this Electronic Speed Controller (ESC) to pulse power to the motor phases. If the high-current MOSFETs within this board fail due to thermal stress or a previous over-current event (like hitting a thick patch of grass), the motor will fail to commutate, resulting in no blade rotation even if the mower powers on.

Handle Wiring Harness
EGO mowers utilize a folding handle for storage, which creates a point of mechanical stress for the internal signal wires. Over time, the copper strands inside the insulation fatigue and break, severing the communication link between the bail lever/start button and the motor controller, effectively preventing the 'start' command from being received.

Bail Switch Assembly
This electromechanical switch is the primary safety interlock for blade engagement. Internal contact corrosion or mechanical failure of the spring-loaded actuator prevents the completion of the start-sequence circuit, which is a prerequisite for the controller to energize the blade motor.
