LG Air Conditioner Overload Protector - EAF34140251

Protect your cooling system's heart with the LG Air Conditioner Overload Protector (EAF34140251). This vital safety component is designed to monitor the electrical current and temperature of the AC compressor. If the compressor draws excessive power or begins to overheat, the overload protector automatically breaks the circuit to prevent permanent motor burnout or electrical fires. A failing protector may cause your compressor to "click" but fail to start, or cause the unit to shut down prematurely during hot weather.

Built with high-sensitivity bimetallic elements and heat-resistant housing, the EAF34140251 provides a reliable line of defense against electrical surges and mechanical strain. Replacing a weakened or tripped protector is a cost-effective way to extend the lifespan of your expensive compressor and ensure the safety of your appliance.

1. Safety First: Completely power off the air conditioner and unplug it from the wall. For window or split units, ensure the power is disconnected at the source.
2. Access the Compressor: Remove the outer cabinet or access panel of the outdoor unit (or rear of the window unit) to locate the compressor.
3. Remove the Terminal Cover: Locate the plastic cover over the compressor terminals and remove the retaining clip or screw to reveal the wiring.
4. Identify the Protector: The EAF34140251 is typically mounted directly against the compressor housing or inside the terminal box. Note the wire positions before disconnecting.
5. Swap the Part: Disconnect the leads from the faulty protector and remove it. Install the new overload protector, ensuring it makes firm contact with the compressor surface for accurate heat sensing.
6. Reassemble and Test: Reconnect the wires, replace the terminal cover, and reattach the unit's outer casing. Restore power and monitor the compressor as it kicks on to ensure smooth operation.
7. Compatible with select LG air conditioner models, this OEM-quality protector ensures your system remains safe under heavy cooling loads.
