The Propeller Fan Assembly is an OEM part for LG window air conditioners. As the primary cooling component, the fan assembly endures constant rotation circulating air throughout interior spaces.

Causes of a damaged fan assembly can include bearing deterioration over extended run times. Foreign object contact or abrasion may also degrade protective coatings prematurely.

Symptoms of a bad Propeller Fan Assembly include:

• Abnormal vibration or noise during operation
• Reduced airflow throwing capacity
• Inability to maintain consistent temperature control
• Premature motor or electronics failure from excess stress

This OEM LG part is also compatible with some Kenmore models.

This is the main printed circuit board (PCB) assembly that controls core appliance functions and user interface signals. Replacing a faulty main board restores command and communication between sensors, motors and display. What it does:

• Manages appliance control logic and timing for operational cycles
• Sends and receives signals to/from user controls, sensors and actuators
• Helps regulate motor, valve and compressor operation via command relays
• Commonly replaced for failure symptoms like no power to console, unresponsive controls, or erratic operation

• Power off and unplug the appliance before starting any repair
• Handle the board by edges and avoid touching components or connector pins
• Note and document connector locations before removal to ensure correct reconnection
