Part: Condenser coils

Compressor overworking or failing

How to Identify: Compressor area very hot to touch, louder-than-normal compressor noise, fridge not cooling adequately.

Part: Compressor

Restricted airflow within the cabinet

How to Identify: Blocked vents by food items, uneven cooling zones, temp fluctuations.

Part: Internal airflow pathways
