Common causes for this symptom.
-
Evaporator fan motor failed.
The fan that pushes cold air from the freezer into the fridge has stopped or seized. Common on units 5–7 years old.
-
Defrost cycle stuck.
Frost has built up on the evaporator coil and is blocking airflow. The defrost heater, thermistor, or timer needs replacement.
-
Damper door stuck closed.
The flap that opens to let cold air into the fridge compartment is mechanically jammed or its motor failed.
-
Control board fault.
The main control board is no longer cycling cooling correctly. Less common, but seen on Samsung, LG, and integrated Sub-Zero units.
