How to Fix / Troubleshooting

Safety first: Unplug the unit before cleaning or inspecting the fan.

Steps:

  • 1. Clean filter and grilles: Wash or replace the filter and vacuum dust from intake and discharge grilles.
  • 2. Inspect fan blade: Ensure the blade is properly positioned and secured on the motor shaft.
  • 3. Check for obstructions: Remove any plastic, insulation, or objects blocking airflow inside the cabinet.
  • 4. Ducted units: For whole-home Carrier dehumidifiers tied into ductwork, inspect ducts for collapses or closed dampers.
