LG Refrigerator Airflow / Evaporator Fan or Duct Blockage

Freezer cold but refrigerator warm; little or no air coming from refrigerator vents.

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

Failed refrigerator evaporator fan motor, Ice blockage in air ducts, Stuck air damper, Evaporator coil heavily frosted due to defrost failure

Safety: Unplug the refrigerator before removing interior panels.

Check vents: Ensure vents in the refrigerator are not blocked by food items.
Listen for fan: With the door switch held closed, listen for the refrigerator fan. If silent, suspect the fan motor.
Inspect evaporator: Remove the rear interior panel in the fresh food section. If the coil is encased in ice, defrost it and test the defrost heater and thermostat.
Check damper: On models with a damper, verify that it opens when the refrigerator calls for cooling. Replace if stuck closed.
