About this item

The LG Air Conditioner Main PCB Assembly (Part Number / SKU: EBR43117003) is an authentic OEM electronic control board designed for compatible LG air conditioner models. The main printed circuit board (PCB) acts as the central nerve center, receiving user commands from the remote control or display panel and regulating power relays, fan motors, and compressor signals. Over time, voltage fluctuations, power surges, or moisture exposure can damage internal microcontrollers or traces, leading to a dead unit, failure to cool, or erratic operation. This genuine OEM replacement board restores factory-calibrated cooling performance and electrical safety.

Key Features

  • OEM Central Processing Unit: Factory-programmed main control board designed specifically for exact model compatibility and seamless communication across all internal AC peripherals.

  • Integrated Power & Relay Switching: Features robust onboard relays, transformers, and microprocessors to handle heavy-duty air conditioner electrical loads safely.

  • Precise Firmware Integration: Comes pre-loaded with official AC operating logic to manage precise temperature setpoints, compressor timing, and error monitoring.

Benefits

  • Solves major air conditioner failures like complete lack of power, unresponsive remote inputs, failure of the compressor or fan to engage, and persistent electronic error codes.

  • Restores factory-grade operational reliability and electrical safety.

  • Direct plug-and-play wiring harness integration eliminates modification hurdles during advanced servicing.

Applications Designed for compatible LG air conditioner models requiring main control board part number EBR43117003.

What's Included

  • 1 x Genuine LG Air Conditioner Main PCB Assembly Control Board (EBR43117003)

Usage Instructions

1.Unplug & Isolate Power:Prep.

Disconnect the air conditioner entirely from the main AC electrical power supply or switch off the dedicated circuit breaker before starting work.

2.Swap & Connect:Replace.

Remove the indoor unit casing/control box cover, carefully unclip and photograph all wiring harnesses connected to the old board, unscrew the mounting chassis, install the new EBR43117003 PCB, and reconnect all plugs securely.

Safety Instructions

Safety Warning

Always disconnect the main electrical power supply before servicing internal AC electronics. Electrostatic discharge (ESD) precautions should be observed when handling circuit boards. Improper wiring can cause severe electrical shorts or component damage.

Care Instructions

  • Ensure the indoor unit electronic control enclosure remains completely dry, clean, and free from dust or moisture accumulation to prevent premature board failure.
