How to Fix / Troubleshooting
Safety first: Turn OFF and unplug before opening the housing. Do not insert fingers into moving parts.
- Inspect fan area: Remove the outer cover to access the fan. Check for loose screws, broken plastic, or foreign objects (e.g., small toys, debris).
- Clean fan blades: Use a soft brush or compressed air to remove dust from the fan blades and motor vents.
- Tighten hardware: Tighten any loose screws securing the fan or motor bracket.
- Replace motor: If the noise persists and the motor feels rough when spun by hand, the motor bearings are likely worn. Replace the fan motor assembly with a compatible Vicks motor.
