How to Fix / Troubleshooting
Safety first: Unplug the appliance if the noise is accompanied by smell, heat, or malfunction.

- 2. Check placement: Ensure the appliance is not touching other objects that can resonate.
- 3. Avoid further stress: Do not run at maximum power for extended periods until checked.
- 4. Service if persistent: Internal power electronics or the motor drive may be failing and should be inspected by a technician.
