How to Fix / Troubleshooting

Safety first: Remove the battery before opening the housing. Do not touch moving parts while powered.

  • 1. Inspect fan area: Remove canister and filter. Look for debris stuck to the fan or signs of broken blades.
  • 2. Check motor mounts: Open the housing (if out of warranty) and verify that all motor mounting screws are tight and rubber isolators are intact.
  • 3. Clean fan: Carefully remove any debris from the fan blades. Do not bend the blades.
  • 4. Replace damaged fan/motor: If blades are broken or the fan is visibly warped, replace the entire motor/fan assembly.
  • 5. Reassemble securely: Ensure all housing screws are tightened evenly to prevent resonance.
