Could a failing Trigger Switch Assembly cause the RYOBI ONE+ 18V LEAF BLOWER to have symptom: General Troubleshooting?

The internal contacts of the switch assembly are subjected to high inrush currents every time the blower is activated. Over many cycles, electrical arcing can cause these metallic contacts to 'weld' together, creating a permanent electrical bridge that keeps the motor energized. Replacing the assembly provides a new switch and a fresh mechanical return spring.

Could a failing Electronic Speed Controller (ESC) cause the RYOBI ONE+ 18V LEAF BLOWER to have symptom: General Troubleshooting?

If the physical trigger moves freely but power remains constant, the MOSFET (metal-oxide-semiconductor field-effect transistor) inside the controller has likely suffered a thermal failure. When these components fail, they typically fail in a 'shorted' state, allowing current to flow continuously from the battery to the motor regardless of trigger input.

Could a failing Trigger Return Spring cause the RYOBI ONE+ 18V LEAF BLOWER to have symptom: General Troubleshooting?

This is a purely mechanical failure where the torsion or compression spring responsible for pushing the trigger back to the 'off' position has snapped or slipped. Without this counter-force, the physical trigger remains in the depressed position, keeping the internal microswitch engaged.
