Ensure reliable motor startup and stable electrical performance with the LG Air Conditioner Film Box Capacitor (EAE42718003). This essential electrical component stores and delivers the precise burst of energy required to jump-start the fan motor or compressor and maintain their smooth operation. If your air conditioner is humming but the fan won't spin, the unit struggles to turn on, or it shuts down unexpectedly, a degraded, swollen, or failing capacitor is often the cause. Replacing this part is a crucial step in restoring full functionality and preventing costly damage to your unit's motors.

Housed in a durable, heat-resistant casing, the EAE42718003 features high-quality film dielectrics designed to handle the rigorous electrical demands and temperature fluctuations of modern cooling systems. Its stable capacitance ensures consistent power delivery, reducing electrical strain and improving the overall efficiency and lifespan of your air conditioner.

1. Safety First: Completely power off the air conditioner and unplug it from the wall, or shut off the dedicated circuit breaker. Crucial Safety Step: Capacitors hold a dangerous electrical charge even when unplugged. Use an insulated screwdriver to bridge the terminals and safely discharge any stored voltage before handling.
2. Access the Electrical Compartment: Remove the unit's outer casing or control panel cover to locate the internal electrical box where the capacitor is housed.
3. Document the Wiring: Before disconnecting anything, take a clear photograph of the wires connected to the old capacitor to ensure proper placement during reassembly.
4. Remove the Old Capacitor: Carefully unplug the wire spade connectors using needle-nose pliers. Remove the screw or clip holding the mounting bracket and pull the faulty capacitor out.
5. Install the New Part: Secure the new EAE42718003 film box capacitor into the mounting bracket and reconnect the wires exactly as they were documented in step 3.
6. Reassemble and Test: Replace the electrical cover and the unit's outer casing. Restore power and turn on the AC to verify that the motor starts up smoothly and operates quietly.
7. Compatible with select LG air conditioner models, this OEM-quality film box capacitor provides the exact electrical rating required to guarantee factory-standard performance and safety.
