What this issue means

Start here
First checks
Identify whether the sound comes from the LiDAR. If it is only the normal faint LiDAR hum, no action is required. If the sound comes from elsewhere, check for foreign objects trapped in the wheels and inspect whether a blade is broken.
Inspection
Area to inspect
LiDAR sound source, drive wheels and cutting blades.

What to do next
Do not replace LiDAR components solely because of the documented faint operating hum. If wheel debris and blade damage are ruled out but the abnormal noise remains, use qualified service support for further diagnosis.
