Possible Causes
Severely clogged air filter, Blocked intake or discharge grille, Fan blade loose on shaft, Collapsed duct (for ducted Carrier dehumidifiers)
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.
