LG Washing Machine PCB Assembly,WiFi

The LG Appliance RF PCB Module (Part Number: EBR85871801) is an authentic original equipment manufacturer (OEM) replacement smart wireless interface circuit board designed for LG washing machines, dryers, and washer-dryer combination units. Installed inside the main control console or display panel housing, this radio-frequency / Wi-Fi module enables wireless communication between the appliance's main control board (PCB) and home Wi-Fi networks. It powers smart features like remote start, cycle monitoring, downloadable customized programs, and Smart Diagnosis via the LG ThinQ mobile platform.

Key Features

• Integrated RF / Wi-Fi Transceiver: High-frequency communication chipset housed beneath a protective RF shield can to ensure strong, interference-free wireless signal reception.

• On-Board Polarized Wire Header: Features a pre-soldered keyed connector socket for direct, snap-in ribbon harness connection to the main display controller.

• Compact Low-Profile PCB Form Factor: Sized for exact slot fitment inside console housing brackets with pre-aligned locating tabs and mounting screw points.

Benefits

• Solves smart pairing failures, machine disconnecting from home Wi-Fi, unresponsive ThinQ app controls, or failure to register the appliance on the wireless network.

• Restores remote cycle tracking, smart energy management, and over-the-air appliance diagnostics.

• Direct OEM replacement guarantees factory firmware compatibility, antenna tuning, and plug-and-play installation.

Applications

Designed specifically for select LG ThinQ-enabled washing machines, dryers, and washer-dryer combination units requiring part number EBR85871801.
