Frequently asked questions

Should I worry about a whining noise from my motor?

A light hum is normal, but a new grinding or clicking noise usually signals worn bearings or gears that need attention.

Can the noise come from something other than the motor?

Yes - loose mounts, the controller, or a dragging brake can mimic motor noise. A proper diagnostic finds the real source.
