Part: Evaporator or condenser fan
Improper leveling or vibration amplification
How to Identify: A 'gatta‑gatta' or amplified vibration noise often when door opens/closes or fridge runs; confirmed by placing level on top.
Part: Mounting/feet and surface interface
Compressor load noise
How to Identify: Low booming or humming primarily at compressor location; louder than normal during heavy cooling cycles.
Part: Compressor
Internal airflow obstructions and refrigeration load
How to Identify: Sound from within compartment, often linked to blocked vents by food items causing fan strain.
Part: Internal storage and circulation paths
Frost/ice contacting moving parts
