Refrigerator Noisy Due to Faulty Condenser Fan Motor

To confirm if the condenser fan motor is the source of the noise, unplug the refrigerator and carefully move it away from the wall. Access the condenser fan, usually located near the compressor at the bottom rear. Visually inspect the fan blades for obstructions, debris, or damage. Gently try to spin the fan by hand; if it feels stiff, wobbly, or makes a grinding sound, the motor may be failing. Re-plug the refrigerator and listen closely to the fan's operation when the compressor kicks in, noting any buzzing, chirping, or excessive vibration emanating specifically from this fan area.
