Could a failing Evaporator Fan Motor cause the LG FRIDGE LFCC22426 COMPRESSOR to have symptom: Noise?

This DC motor is the most frequent source of 'abnormal' noise in LG French Door units. Failure is usually characterized by a high-pitched chirping or grinding sound that originates from the freezer or fresh food compartment. The noise typically stops when the door is opened, as the control board interrupts the fan circuit, confirming the motor or fan blade is the root cause.

Could a failing Condenser Fan Motor cause the LG FRIDGE LFCC22426 COMPRESSOR to have symptom: Noise?

Located at the bottom rear of the unit, this fan cools the compressor and condenser coils. Over time, the bearings can fail or the blades can become obstructed by dust and pet hair, leading to a constant growling or vibrating noise that is audible from the back of the refrigerator while the unit is cooling.

Could a failing Universal Compressor Replacement Kit cause the LG FRIDGE LFCC22426 COMPRESSOR to have symptom: Noise?

The LG Linear Compressor is subject to internal mechanical wear that can produce a loud, metallic rattling or high-decibel humming noise. While this noise often precedes a total loss of cooling, it is a known failure mode for this specific model series where the internal piston or valve assembly degrades.

What is the most likely root cause for a LG FRIDGE LFCC22426 COMPRESSOR with symptom: Noise?

LG FRIDGE LFCC22426 COMPRESSOR Noise

✅

System Nominal

Most noises in this LG model, specifically popping, clicking, or gurgling, are the result of normal thermal expansion of the internal plastic liners and the movement of refrigerant through the system. According to the manufacturer, these sounds are standard operational indicators and do not require repair unless they are accompanied by a lack of cooling or are excessively loud grinding/screaming sounds.

NO REPAIR ACTION REQUIRED. PHYSICS CHECK CONFIRMED.
