Possible Causes
Failed soft-start circuit on PCB, Burned relay or MOSFET, Internal short in motor windings, Overcurrent damage from previous blockage
How to Fix / Troubleshooting
Safety first: Remove the battery pack. Do not attempt to open the motor housing unless you are trained in electronics repair.
- Check for mechanical blockage: Remove all accessories and filters and ensure the motor intake is clear. A severe blockage can cause overcurrent that damages the soft-start circuit.
- Smell test: With the battery removed, smell near the motor vents. A burnt electronics smell suggests PCB or motor damage.
- Do not repeatedly trigger: Avoid repeatedly pulling the trigger in this condition; it can worsen PCB damage.
- Service required: This fault almost always requires replacement of the motor housing assembly (which includes the control PCB and motor). Provide your Makita model number to obtain the correct assembly.
