Possible Causes
Burnt-out main motor windings, Failed MOSFETs on motor drive section of PCB, Shorted motor connector, Internal wiring harness damage
How to Fix / Troubleshooting
Safety first: Remove the battery pack. Do not continue trying to start a vacuum that smells burnt or emits smoke.
- Smell and sound check: If you previously noticed a burning smell or unusual noise before failure, the motor is likely damaged.
- Visual inspection: Look into the motor air intake for signs of soot or melted plastic. Do not insert tools into the motor housing.
- Check for obstructions: Ensure there are no foreign objects lodged near the motor inlet that could have caused overload.
- No user-level repair: The motor drive circuit and main motor are internal components requiring disassembly of the handheld unit. This should be done only by a qualified technician. Arrange for service or replace the handheld main body if sold as a separate part.
