How to Fix / Troubleshooting

Safety: Unplug the dehumidifier before servicing.

  • Inspect fan area: Remove the front or rear cover to access the fan. Look for debris or objects caught in the blades.
  • Check clearance: Ensure the fan wheel is not rubbing against the shroud or housing. Adjust position if necessary.
  • Tighten hub: If the fan is mounted on a shaft with a set screw, tighten it to eliminate wobble.
  • Replace fan motor or wheel: If the motor is noisy when spun by hand or the wheel is cracked, replace the fan motor assembly or blower wheel with Medisana-compatible parts.
