Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the unit before cleaning or accessing the fan area.
- Step 1 – Clean filter: Remove and wash the air filter thoroughly. Let it dry completely before reinstalling.
- Step 2 – Check grilles: Ensure nothing is blocking the intake or exhaust grilles. Maintain adequate clearance around the unit.
- Step 3 – Inspect blower and coil (advanced): Remove the front or rear cover to access the blower wheel and evaporator coil. Vacuum dust from the coil fins and blower blades using a soft brush attachment.
- Step 4 – Check blower wheel for damage: Make sure the blower wheel is not cracked, loose on the motor shaft, or rubbing against the housing.
- Step 5 – Evaluate fan motor: If airflow is still weak and the motor struggles to spin, the fan motor may be failing and require replacement.
When to call a technician: If the blower wheel or motor needs replacement, or if you are not comfortable disassembling the cabinet, contact a service professional.
