Loud buzzing or humming noise from the rear of the IceKing refrigerator.

Safety first: Unplug the refrigerator before reaching near the compressor or fan.

Steps:

• 1. Access rear compartment: Remove the lower rear panel to expose the compressor and condenser fan.
• 2. Inspect fan: Check if the fan blades are contacting wires, insulation, or dust buildup. Clear any obstructions and secure loose wiring.
• 3. Check fan bearings: Spin the fan by hand; if it feels rough or wobbly, replace the condenser fan motor.
• 4. Compressor mounts: Inspect rubber grommets under the compressor. If they are cracked or hardened, replace them to reduce vibration.
• 5. Compressor noise: If the compressor itself is excessively loud or knocking, it may be failing internally and require professional replacement.

Note: Some low-level humming is normal, but sudden changes in noise level warrant inspection.
