Start troubleshooter

What do you notice?

  • A low hum from the ventilation unit.
  • The humming gets worse at a higher ventilation setting.
  • Vibrations through wall, ceiling, or ventilation ducts.
  • The motor still runs but sounds heavier than normal.

Possible causes

  • Worn bearings.
  • Imbalance of fan or motor.
  • Contamination of fan impeller or motor.
  • Resonance of the ventilation unit or ductwork.

What can you check yourself?

Check whether the humming comes from the motor itself or is amplified via the housing or ventilation ducts. Also, observe if the sound changes when you select a different ventilation setting. Always disconnect the power to the ventilation unit before opening it.

Not sure where the humming comes from?
