Possible Causes
Open circuit in cutting motor windings, Damaged cutting motor cable, Faulty motor driver on PCB, Connector pulled loose during previous service
How to Fix / Troubleshooting
Safety: Turn OFF the mower and remove the battery if specified by Makita procedures.
- Check motor connector: Access the underside or internal compartment where the cutting motor plugs into the harness. Ensure the connector is fully seated.
- Inspect cable: Look for cuts, pinch points, or rodent damage along the cutting motor cable.
- Resistance test (advanced): With the motor disconnected, measure resistance across the motor terminals. An open circuit (infinite resistance) indicates a failed motor.
- Reset and test: Reconnect, power ON, clear E16, and attempt to start blades.
If the motor and wiring test good, the motor driver circuit on the main PCB may be defective and require professional replacement.
