Lg Refrigerator 72129 Parts

The Door Switch is an OEM part for LG refrigerators. It is responsible for detecting whether the refrigerator door is open or closed, allowing the appliance to control the interior light and, in some models, the cooling functions accordingly.

Causes of a bad door switch can include wear and tear from frequent use, electrical issues, or physical damage to the switch mechanism. A faulty door switch can lead to improper operation of the refrigerator's light or cooling system, affecting overall performance.

Symptoms of a bad door switch include:

• Interior light not turning on or off properly
• Refrigerator not cooling properly or running continuously
• Door alarm not functioning correctly
• Intermittent or unresponsive switch operation

This OEM LG part is also compatible with Sears/Kenmore.

This fan assembly circulates air through the appliance so coils and internal components operate at the proper temperature. Replacing a failed or noisy fan can restore airflow and help prevent performance issues caused by weak circulation.

• Moves air across coils and components to support designed cooling/dehumidifying performance
• Helps maintain steady airflow to reduce overheating or icing conditions
• A failing fan can cause little to no airflow even when the unit is running
• Common symptoms: fan not spinning, intermittent operation, loud rattling/grinding, vibration, or thermal shutdown

• Disconnect power before servicing to avoid electrical shock or injury
• Access the fan area per your unit's service information; remove panels/shrouds as needed
• Note wire connections and mounting order; transfer any brackets, grommets, or hardware from the old assembly
• After installation, ensure the fan spins freely and clears all shrouds, then test operation before reassembly
