{"product_id":"ebr80362403-air-conditioner-option-pcb","title":"LG Air Conditioner Option PCB - EBR80362403","description":"\u003cp\u003eExpand the capabilities and connectivity of your cooling system with the LG EBR80362403 Air Conditioner Option PCB. This auxiliary printed circuit board acts as a specialized communication and feature module that plugs into the unit's primary control system. It is responsible for managing \"optional\" high-level functions, which may include Wi-Fi connectivity (LG ThinQ integration), centralized controller communication, or specialized dry-contact interfaces for building management systems (BMS). If your unit has lost its smart features, fails to connect to the network, or cannot be recognized by a multi-zone controller, this genuine Option PCB is the essential component for restoration.\u003c\/p\u003e\u003cp\u003eThe EBR80362403 is manufactured with high-precision surface-mount technology and features a protective conformal coating to shield the delicate circuitry from the humidity and temperature variations found within an HVAC cabinet. This ensures stable data transmission and long-term reliability for your system's advanced features.\u003c\/p\u003e\u003cstrong\u003eInstallation \/ Replacement Instructions:\u003c\/strong\u003e\u003col style=\"list-style:none;padding-left:0;margin-left:0;\"\u003e\n\u003cli\u003eSafety First: Turn off the air conditioner and completely disconnect it from the power source at the circuit breaker. Wait at least 5 minutes for the internal capacitors on the main board to fully discharge.\u003c\/li\u003e\n\u003cli\u003eAccess the Control Box: Open the front intake grille and remove the electrical control box cover (usually located on the right side of the indoor unit).\u003c\/li\u003e\n\u003cli\u003eLocate the Option Slot: The EBR80362403 is typically a smaller board mounted on top of or adjacent to the main power PCB, connected by a multi-pin wiring harness or a direct plug-in header.\u003c\/li\u003e\n\u003cli\u003eDisconnect the Wiring: Carefully unplug any communication cables attached to the board. Pull from the plastic connector housing, not the wires themselves.\u003c\/li\u003e\n\u003cli\u003eSwap the Board: Remove the mounting screws or release the plastic standoffs holding the old PCB. Align the new EBR80362403 and secure it firmly.\u003c\/li\u003e\n\u003cli\u003eConfigure and Test: Reconnect the communication harnesses. Replace the control box cover and restore power. You may need to re-pair the unit with your LG ThinQ app or central controller to verify the new board is communicating correctly.\u003c\/li\u003e\n\u003c\/ol\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003col style=\"list-style:none;padding-left:0;margin-left:0;\"\u003e\n\u003cli\u003eAC Auxiliary\/Option Control Board – Part Number: EBR80362403\u003c\/li\u003e\n\u003cli\u003eAdvanced Feature Support: Enables smart connectivity, remote monitoring, and specialized interface modes.\u003c\/li\u003e\n\u003cli\u003eConformal Coating: Protects the board against moisture, dust, and corrosion for enhanced durability.\u003c\/li\u003e\n\u003cli\u003ePlug-and-Play Integration: Designed with factory-standard headers for a secure and direct connection to the main PCB.\u003c\/li\u003e\n\u003cli\u003eEnhanced Communication: Provides stable signal processing for external controllers and network modules.\u003c\/li\u003e\n\u003cli\u003eOEM-Quality Part: A genuine LG replacement component engineered to meet the exact electrical and logic specifications of your air conditioning system.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"LG","offers":[{"title":"Default Title","offer_id":39667106742451,"sku":"EBR80362403","price":11.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/lgparts.com\/es\/products\/ebr80362403-air-conditioner-option-pcb","provider":"LG Parts","version":"1.0","type":"link"}
