How to Fix / Troubleshooting
Safety first: Immediately turn OFF the mower and disconnect from the station. Do not continue to operate until inspected.
- Inspect underside: Check for grass, string, or plastic wrapped around the blade or wheel motor shafts. Remove all obstructions.
- Check for discoloration: Open the cover and inspect the main board and connectors for burnt marks or melted plastic.
- Smell localization: Carefully smell near each motor housing (with power OFF). A strong burnt odor from one motor indicates internal failure.
- Service: Replace any motor that smells burnt or shows signs of overheating. If the smell comes from the PCB, have the board inspected by a technician.
