LG Refrigerator IPM Module

The LG Intelligent Power Module Assembly (Part Number: EAY64669001) is an authentic original equipment manufacturer (OEM) replacement power switching board designed for LG inverter refrigerators. Operating as a critical high-voltage component within the main inverter power circuit, this IPM board receives control signals from the main microcomputer and drives the inverter compressor by synthesizing variable-frequency three-phase AC power.

Key Features

• Genuine OEM Precision Engineering: Factory-manufactured directly by LG to ensure precise voltage regulation, switching frequency, and gate drive parameters.

• Integrated Inverter Power Switching: Features high-efficiency IGBT power switches with integrated gate drive circuits, over-current protection, and thermal shutdown logic.

• Thermal Dissipation Design: Engineered with heavy-duty heat sink attachment points to manage thermal energy generated during continuous high-load cooling.

Benefits

• Solves inverter compressor non-starting issues, compressor error blinks, or total cooling failure.

• Restores energy-efficient, variable-speed cooling to maintain precise compartment temperatures.

• Direct OEM replacement ensures factory-certified electrical safety, exact connector pinout, and seamless PCB communication.

Applications

Designed specifically for select LG inverter refrigerator models requiring part number EAY64669001.

What's Included

• 1 x Genuine LG Refrigerator Intelligent Power Module Board (EAY64669001)

Usage Instructions

1. DANGER: Unplug the refrigerator from the electrical power outlet and wait at least 5 to 10 minutes to allow high-voltage DC bus capacitors to discharge completely.

2. Access the rear control board compartment panel at the back of the refrigerator.

3. Unscrew the cover plate to expose the main inverter PCB assembly.

4. Note wire connector placement and disconnect all harness plugs from the IPM board.

5. Unscrew the mounting fasteners (and heat sink bracket screws, if applicable) securing the module.

6. Install the new LG EAY64669001 module, reattach heat sink thermal paste/fasteners, plug in all wire harnesses firmly, reattach the access cover, and restore main power.

Safety Instructions

• HIGH VOLTAGE WARNING: Inverter control circuitry retains dangerous DC voltages even after power disconnection. Installation should be performed by a qualified appliance service professional or experienced technician taking proper safety precautions.

• Always disconnect main AC power prior to opening control compartments or handling electronic PCBs.

Care Instructions

• Keep electronic board housings clean, dry, and free of dust, debris, or moisture accumulation.
