Kelvinator Restricted Indoor Airflow

The Kelvinator split AC indoor unit blows air, but the airflow is very weak even at high fan speed.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Clogged air filters, heavily fouled evaporator coil, blocked return air path, failing indoor fan motor.

Steps:

Clean filters: Remove and wash the filters with mild detergent; dry them completely.
Inspect coil: Look at the evaporator coil behind the filters. If it is covered in dust, clean it with a soft brush or coil cleaner.
Check intake and outlet: Ensure furniture or curtains are not blocking the indoor unit's intake or discharge.
Fan speed test: Cycle through fan speeds on the remote control. If the speed does not change, the fan motor or its control may be faulty and require replacement.
