Part: Evaporator fan motor

Dirty condenser coils

How to Identify: Visible dust/debris on coils at back/below unit; compressor overheats, fridge not cooling effectively.

Part: Condenser coils

Damaged door gasket/seal

How to Identify: Cold air escapes when closing door; visible gaps, worn or torn gasket edges.

Part: Door gasket

Faulty damper control assembly

How to Identify: Insufficient airflow between freezer and fridge leads to warm fridge but cold freezer.

Part: Damper control assembly

Compressor or start relay failure
