How to Fix / Troubleshooting
Safety first: Unplug the machine immediately if a motor hums without turning.
- Check for mechanical jams: Ensure the brush roller and fan intake are free of obstructions. A jammed component can stall the motor.
- Do not keep trying to start: Repeated attempts can overheat and burn out the motor windings.
- Professional diagnosis: A humming motor usually indicates internal motor or capacitor failure. The motor assembly should be tested and replaced by a technician.
Operating a stalled motor is dangerous and can cause rapid failure and electrical hazards.
